Pool Building and Repair

Pools can be constructed either in or above the ground and requires materials such as metal, concrete, fiberglass or plastic. As pools age, they may develop cracks, hollow spots and chipping, which require repair.

What is so special about black-bottom pools?

Colored surfaces are basically an aesthetic choice by the owner of the pool. It is a myth that the darker the surface the warmer the pool. To illustrate, put a black plate and a white plate in the bottom of the pool. Remove them a few hours later and see if there is any temperature difference between them. There won't be. I've tried this. Water absorbs all the heat from the sun in the top 12 inches and never has a chance to reach the bottom. I have also monitored the temp. in white and black bottom pools that were next door to each other and had virtually identical conditions....no difference. Actually I have done this 3 times in the last 34 years to prove this point. Won a $500 bet on one them:-) Evaporative cooling is the single most important factor in pool temps. Every 7 mph of wind velocity doubles the evaporation rate.

How much does it cost to resurface and replace coping for an average size swimming pool?

It depends on many factors including the type of surface you choose (Diamond Brite, White Plaster, Pebbletec, etc.), and the type of coping stones, but I would estimate around $3,000 and $6,000.

How much should a 25 x 45 inground pool poured concrete no decking two lights auto cover polaris cleaner and pool heater cost?

  • In spring 2010, we put in an 18x40 in Oklahoma. With all the bells & whistles, it came to about 30k. That included a diving board, $3,000 slide, 8' concrete in the back for the diving, 6' over where the slide is, 4' around the rest. A salt water system, vinyl 30mm liner, concrete coping around the edging, Roman style steps in the low end, the safety winter cover, 2HP pump (my pump is about 75' from pool), plus about 100sq ft more concrete back to our patio and I think that's about it.
  • We have 2 skimmers, 2 bottom intakes in the deep end, 1 wall intake for the vacuum. 4 returns back into the pool + the slide return which is also plumbed from the pool, so the pool water runs through the slide which is NICE! So no cold hose water.
  • My suggestion is to Internet research styles. I kinda knew what I was looking for when I walked in, then they suggested some of the extras like the coping around the pool edging where it meets the concrete. Normally there's a metal part that the concrete meets to, the cantilever coping added a nice finish too it.
  • And from my past building experiences, I searched for a company that had an office. Most of these builders around here just have a cell number. I wanted an office that I can go to if things went out of whack. I was turned off by a few fiberglass pool installers because one number went to a guys house, and the 2nd contractor went to his cell phone.
  • Be prepared, the installation destroys the yard.
  • It depends where one lives. In Northern California, your configuration would cost between $25K to $35K, depending on the contractor.
  • We live in Southern California. We are currently in the last and most trying stages of our development. Our contract price was a bit over $40,000 and I've battled to keep it that amount. Each time they have deemed it necessary to increase the cost with some unforeseen feature, I take away something which I can complete myself. Our features include: 14x28' pool. 7' diameter spa. Pebblecoat. No decking provided by builder. salt water system. Faux boulders and edging. Redwood bridge with shear decent water falls off both sides. Heater. Cleaner. No landscaping by builder. Baja reef with sitting boulder. 30' contiguous underwater bench. 3 pool lights and 1 spa light(Sounds excessive, but with the Black Pearl pebblecoat, it's a safety issue for me). When the builder is done, I anticipate a great pool, only to be surround by a dirt wasteland until I build the necessary arbors, patios, decking and landscaping. If I could have dug the hole myself, I would have. The rest will be completed with the 2 hands which are currently typing this response.
  • It depends on where you live, if your backyard is dirt or dirt with big rocks, size, if a truck can get through to the backyard or if a bobcat has to be used, and what all you want in a pool.
  • If you are getting bids from different companies, you need to look at how long they have been in business. You can go with a company that has been in business for 5 years and the next year they go out of business and you can not do a thing about any problems that you have with your pool.
  • Go with a company that has been in business for at least 25 years and does more than just build pools. Look for a company that builds, remodels, and services pools. Also look for a company that has a retail store and has a monthly service department.
  • You really want to stay with a company that can accommodate all your needs when it comes to your pool!
  • I live in the Ohio Valley and we're getting estimates on an 18X36 pool in the neighborhood of $20-25,000, depending on materials. Concrete vs. vermiculite seems to make a difference. I can tell you, though, since you asked about an auto pool cover: friends of ours have one on their 18X36 pool; it cost $8,500! Unless you have serious safety concerns, you may want to stick with a simple solar cover (usually included in most pool package prices), with an deck anchored winter cover (about $1,500). It all depend... Do you want something in the class of a Yugo or VW or the class of a Aston-Martin or Maybach?
  • Pool prices vary as widely as automobiles... a pool is not a pool! What are the soil conditions on your site? Do you have asoils report? What is access like? Do they have to take down a fence between the homes? How far is the closest dirt dump site? Do they get to pile the dirt in your back 40 acres? You get the picture... It depends...
  • Volume pool builders do not supervise production, limit your material selections, build minimal strength pool shells that often times are not sufficient for the site's soil conditions, guesstimate the fluid dynamics (hydraulics & pump sizing), use rebound gunite in their shells, use minimal steel, use single pumps for multiple purposes (results in excess power consumption - as accessories are not used much, and the excess reserve power is spent daily for filtration!), don't use waterproofing compounds in their cements, build flimsy formwork, blah, blah, blah... You get the idea.
  • If you can settle for a few headaches, poor follow through, little back end support. limited selections, then by all means use a volume builder. But quality takes time.... The rule of thumb is don't spend more than 7-10% of the value of your house, on a pool. And remember - cement, steel, lumber, and labor costs are rising exponentially, cement and steel shortages are being experienced in portions of the country! The pools we build average $250,000! (& that's the pool only! No decking, outdoor kitchens, fireplaces, buildings, retaining walls, etc...).
  • A licensed swimming pool professional, will be able to come to your home and prepare you a quote and you will then be able to make an informed decision with that information. Go ahead and make that appointment and your on your way.
  • In the meantime ask yourself how you will use your pool, do you entertain alot, do you like water features? What did you like about the pool on your last vacation? How much time are you willing to spend on maintenance, or will you need full service? Is safety a concern, and what temp. do you like your pool water? Do you think you will want to exercise in the pool much? How many 6' loungers do you think youll need and do you plan on a patio set also? Do your kids plan on having many friends enjoy the pool at their house? Do you want the longest possible pool season. Are you willing to make monthly payments or are you planning on paying out of pocket. I noticed a TV ad for Disney $1,500.00 family of four for a week at the park, FREE-POOL included but you gotta go home after a WEEK, no Exceptions. A pool can be one of the most enjoyable affordable investments for the home. getapool.com good swimming take care.
  • Northern, CA. bay area.......pool only ...38,000 and up.....pool/spa.....50,000 and up........100,000 for pool/spa here is very normal.
  • The relative cost of your swimming pool will be dependent on where you are located and the current state of the local economy. Swimming pools are a luxury industry and also seasonal in many areas creating a niche that is harshly impacted by economic downturn. Slow periods will drive down prices quickly.
  • Steel costs have increased for gunite swimming pools by over 250% in the last five years as an example of why current pool prices seem inflated. Material costs increased with cost of fuel increases, but have yet to drop since fuel prices have lowered.
  • To understand what a pool should cost you should consider what the cost is to build the pool. The pool comes down to engineering, permits, material ordering, framing, steel, plumbing, pressure test, electrical requirements, inspection, concrete application, mud base and perimeter tile, mechanical room plumbing, coping forms, coping pour, interior surface prep, interior finish (marble, stone or crystal based mortar) and the finish and filling of the pool.
  • The raw material and labor costs in Canada to build a gunite pool is around $25-$35,000 depending on where you are located. Typical retain pricing in Canada would be $35,000 on the low end and $65,000 on the high end.

For concrete deck material is Kool Deck or an acrylic considered superior?

As with all design choices, the answer is it depends on what you are trying to achieve. First, let's start with a few basics on understanding the comparison. A genuine Kool Deck brand surface from Mortex Mfg. is a pure cementitious topping unlike an "acrylic", which is a polymer modified cement. A Kool Deck surface will undoubtedly have a lower relative surface temperature than an equivalent acrylic topping of the similar color and will also be more skid-resistant when either wet or dry. A polymer modified cement topping will generally have much better stain resistance than a Kool Deck surface (which can be enhanced to provide similar stain resistance at a cost). Polymer toppings for the most part are deemed easier to apply and require less people for a job. This simplicity does come at a price, as the cost of materials is significantly higher than all the materials required for a Kool Deck surface. The major hurdle for those looking for Kool Deck surface is finding a skilled applicator to insure a proper application - look at the work of the contractor and do your homework!

Bottom line is that a Kool Deck surface is still the best choice for barefoot areas where comfort is king, while polymers are better suited for deck areas expecting staining problems, customer wants custom patterns, or applicators are more comfortable installing the latter.

Sun Deck is an acrylic concrete deck finish that is very durable, stain resistant, and cool. Also quite popular in South Texas.

AnswerWe had the same problem. I scoured libraries, bookstores and the net. I tried engineers as well. We were looking to build our own indoor pool - there are seemingly no experts that cover the construction, humidity concerns etc... My best reference was the internet and about 400 hours plus. I grew up with a pool, ran a pool - including maintenance - but always outdoors. I looked for postings in the end in which people were asking for help with specific problems ie leaks, mold, shifting etc... so I could troubleshoot. We've built our own indoor pool - saving thousands and thousands of dollars and haven't had any problems. I would do it again in a second. Do you have a specific question? I'd love to help if I can, thanks, Kelli AnswerI built my own pool a few years back in Chandler Arizona.

It took a bunch of work and research on my part and a lot of time. I documented my experience on a website:


AnswerBuild your own pool information -- you can get it from many sources, but the swimming pool professional starts with the Bible from ANSI/NSPI, not to mention many hours of TECH Cert classes, mfgr seminars, state and local requirements, advanced schooling, just to name a few.

Non-licensed individuals rely on OJT, friends and what engineers know as SWAG.

It's easy to hire a swimming pool professional, engineer, or architect to handle your project. You get what you pay for and piece of mind when you hire a professional who is licensed and insured.

Are your looking for a reference on construction codes for an inground pool. The latest codes are ANSI/NSPI-5 2003 55 Pages of the most current codes adopted by most building officials. This is just one reference for sale. Last I knew you could order it from ANSI for around 200.00. You cant expect your local library to keep current on construction building codes, on the budgets they have a hard time keeping up on the newest poly sci rags.

On a very serious and noteworthy item is dual main drains, you're responsible for building with the most current standards as the contractor. You will also note changes to slope and walls in all swimming pools. Believe me the old liners cheap and for sale show up every day that do not meet code. Every day I find many suppliers unaware of changes that's a real fact. Swim safe hire a licensed insured swimming pool professional.

ANSWERBuy the pool kit through a reputable pool dealer, get plenty of advice and have someone reliable guide you through it, tell you the next step, a man who has built pools and knows what they are doing.

What are the advantages and disadvantages of vinyl vs fiberglass pools in northern Illinois?

Vinyl or Fiberglass in Illinois="h2headingh2"style="color:rgb(0,0,0);"name="vinyl_or_fiberglass_in_illinois">The advantages of vinyl are many, but first understand the true facts:

-- First, no manufacturer of fiberglass pools guarantees against cracks. Period.

-- Second, all pools can have problems when the water is emptied; when leaks are not repaired in a timely fashion; or when the water is lower than the surrounding groundwater.

Fiberglass pools are great: They can be installed with fewer subcontractors and in less time than a gunite pool. And they also have a smooth surface. Gunite pools have many choices and are not limited in size, shape or depth. They also have many smooth surface options and color choices and warranties vary.

Last and most important: YES, it takes a professional to install any in-ground swimming pool. If you don't hire one, you most likely will not get a good pool -- no matter what the shell is constructed of. It takes many years to learn to be a pool professional; this is not a craft that happens overnight.

Hire a professional, licensed, insured pool pro to get the pool you expect and to save money in the long run. Read your warranty: The fiberglass manufacturers have great warranties, as do the gunite manufacturers and even the Vinyl Liner in-ground pools alike.

Here is more input from others:="h2headingh3"style="color:rgb(0,0,0);"name="here_is_more_input_from_others:">
  • I have spoken to several people and was told that if you have a lot of clay in your soil and there is heavy rain, the fiberglass can actually pop out of the ground and float in the hole created for it (along with breaking up the surrounding concrete decking). My viewpoint is that it would be cheaper to spend $3,000-$5,000 to replace a liner.
  • I have owned all 3 types of pools (vinyl, fiberglass and concrete) in Michigan. Fiberglass pools are 10 times easier to maintain and much easier on the kids' feet. The rumor about fiberglass popping out and cracking is ridiculous. The concrete pool I owned did crack and the vinyl pool ripped twice in 3 years. My Viking fiberglass pool is guaranteed forever against cracking!
  • Both fiberglass and gunite pools offer excellent family fun centers. Quality is very high in each product. Fiberglass is limited by shape and size over gunite or vinyl liner. The surface of all three pools is excellent, and like any other product will yield excellent service with reasonable maintenance. If you are looking for excellent value, great family fun and a lasting investment at your home, nothing compares to an affordable in-ground swimming pool. A properly installed in-ground swimming pool, by one of the many industry-licensed professional builders, will last much longer than 35 years. ="margin-right:0px">


I am a fiberglass swimming pool installer. 12 years and counting with A++ knowledge and record. FYI- I have scene floating gunite pools and floating vinyl liners. If a pool develops a leak or the ground shifts or flooding occurs, it does not matter what type of pool you have, if there is more water on the outside of the pool shell than on the inside, something has to give. The liner pools develope floating liners even being full if there is a ground water issue and no precautions are taken during the install. Such as sump systems for the ground water.

Fiberglass Is 17 times denser that concrete giving it strength and more flexibility. I have seen them move up to as much as 5'' and hold their integrity.

Now. If the proper installation is applied to the life time warrenty shell, it to can be a lifetime backyard enjoyment for the family. The installation preperation and consideration of all elements and ground conditions to the area makes each and every pool install differant. Never one the same. So look at all of the variables involved with your backyard and keep in mind, If I you willing to spend your hard earned money on something that needs to last at least 20 plus years, what can be done during the install to help the projects longevity and your future sanity?="margin-right:0px">

Can you put ceramic tile over fiberglass steps in a liner pool?

yes you can put tile over almost anything. The most important item would be that the mastic / or adhesive would be required to be a water proof, (non affected) type, and dry with a certain amount of flexibility. The best type is a silicone based adhesive that will remain a little pliable. There can be no water during the adhesion process though, and you will not be able to use a normal grout. They make grout simulated materials that are similar to silicone as well, but without sheen and therefore give a finished look.

How do you find a leak in the vinyl liner of an above ground pool?

Here are more recommendations from other WIKI ers:

  • This may not be the answer your looking for, but we used goggles and just went around looking really carefully. It took a while but we did it! There were small air bubbles around the hole - actually we found four holes, but at least we got them!
  • We've had our pool for about 12 years (are in the process of possibly replacing it) and have had only one hole in liner in all those years. The way I found it (yes, the water appeared to be draining, first) was that the grass in an area around the pool was much greener than anywhere else. So, diving down around that area I found the slice in the liner, actually fairly quickly, and placed a wet patch on it, which held thereafter.
  • First check the perimeter of the pool for soaked areas or look at the sand cove and see if any craters have formed, as the water washes away the sand it will leave a ctater in the floor. For small leaks try this. Turn off your pump so the water is still. I put in a dozen OS so 3" squares of paper towels scattered through out the pool. As the water leaks out it will drag a couple pieces of paper towels to the leak. This method has worked for me in the past for small leaks.
  • We were told to use red food coloring. When you drop it in the water, it will be pulled towards the hole. It can take awhile.
  • Use a rubber hose to listen for the leak! Fill with water, plug both ends and put one end to your ear, and probe around the liner with the other end. Make sure it's a quiet evening and believe it or not, even a small leak makes a lot of noise. If you have some electronics background, a small microphone encased in epoxy and a good audio amp will make a excellent leak finder.
  • You sound like you are sure that you have a leak and the answers above cover that. I just wanted to offer a hint to anyone that isn't sure whether they have a leak or if the water is just evaporating. Fill a bucket full of water - level with the pool - and place it on the step - if it is evaporation - the level should drop about the same.
  • The most common way to locate a leak is to swim to the bottom of the pool with a bottle of food color. Squeeze a drop or two by seams or other suspicious locations. The leak will draw the water towards and out of the hole. It is helpful to wear a pair of gogles and to drain the pool leaving about three to four feet of water.
  • See the Related Link for "Use this in your pool to fix ANY leak" to the bottom for the answer.
  • I used ink (specially made for pools) to find my leak and it worked, after looking for days and even over looked the spot where the leak was found. It was until I read this how to and specifically the one about the creaters that are formed on the floor of the pool; that is exactly where the leak was. Also the water outside the pool was in line with the crater.
  • I used Automotive Goop to make repairs in the vinyl liner from the outside. If the hole is small you can wipe away the running water, clean the surface with paint thinner, and apply the Goop to the hole. The water may leak through at first, but apply pressure and smear it into the hole and the leak will hopefully stop. (I lick my finger to prevent the goop from sticking to my skin so I can work it) It worked for me on numerous holes (my crazy dog goes ballistic over water and won't stop jumping at the walls:)and it is a cheap fix. After the first application is dry, add more layers.

How do you repair a heaving pool deck?

You probably need to have the leak fixed that is most likely causing the deck to heave.

Determine why the deck heaved. Trees and ground movement can also cause decks to heave. Sometimes you can cut the deck at a control joint and it will drop back down. If it is saturated expansive soil the source of the water must be stopped. I have seen decks go back down when the soil dried out as long as no soil displacement occurred. Most of the time however you need to remove the bad part and replace it.

What is pool gunite?

Summary: A mixture of cement and sand sprayed onto contoured and supported surfaces to build a pool. Gunite is mixed and pumped to the site dry, and water is added at the point of application. Plaster is usually applied over the gunite. The plaster is actually the material that is visible and that comes into contact with the water (not the underlying gunite cement structure).

More details: "Gunite" is a trade name for "dry gunned" concrete, invented and patented by a North Carolina man. The term "gunite" has been used so much that, to most people, it means spray applied concrete. People often talk about a gunite pool -- meaning a concrete pool where the concrete is pneumatically applied or sprayed in place using air pressure. Many of us in the concrete spraying business have started using the term "dry gun" to delineate this process.

"Dry gun" means the cement and sand are injected into an air stream conveying it to the nozzle. The nozzle operator then adds the water at the nozzle and has total control of the water-cement ratio. The delivery hose of the mix is generally quite light, as the hose is mostly filled with air containing the mix of cement and sand.

Which pool is better - fiberglass or plaster?

That is a lot like the Question: Which is better Ford,Chevy or GMC. It is all personal preference. A pool manufacturer has to meet strict guidelines in order to offer their goods to the public. It's not a matter of opinion, there are many differences in the fiberglass pool you purchase. Most fiberglass pool manufacturer's do offer a lifetime warranty of the structure of the pool but the surface warranty is very important as well. Most pool companies that install pools do not bring this to your attention because only three companies have a some what representable warranty. Most manufacturer's only have a one year surface warranty only covering osmotic blistering. Composite Pools and Viking offer a 3 year unconditional and 4 year pro-rated. Leisure Pools actually offers the best warranty on the surface with a 10 year unconditional warranty covering not only osmotic blistering but surface yellowing, cobalting, fading and discoloration and hairline cracks. So no it is not a matter of opinion it's simply the truth, you must look in depth about the pool warranty, it can tell you a lot about the product. First please hire only a licensed and insured pool builder. Which pool is better? Fiberglass is a good choice, and will last a lifetime but must be installed properly! Your pool professional did not learn to build quality overnight, and it takes years of experience in many areas of construction to become a pro. So since it takes years of experience to be a pool builder, you get what you pay for. Most find the sweetness of an unusually low price are long forgotten by the horror of expensive litigation or something worse.

How do you level the ground for an above ground swimming pool?

Level Own Lawn for Pool
  • It can be done. We just did it. After clearing all the sod, and dirt away for the depth that you want, you need to take a 4 foot 2x4, and tape a level to it. Then you need to slide, and smooth the sand that has been laid. **Note, it is easier to level it once you have the sand laid.
  • Continue to check it in all directions. When leveling, it is also important to know that where your supports go, (the track and the wall of the pool) is the most important part that needs leveled. The inner part can be eyed for levelness, and smoothness. You will need to lay your block, and then check with a string level to make sure that all sides are level one across from the other.
  • You have to put sand on it and level with a rake.
  • After sod has been removed and sand has been placed in area construct a square box out of 2x4 boards that are straight make box 48" square place 2 more pieces between square equal distance apart place 2 eye bolts equal distance apart on one end connect cable or chain to riding lawn mower. now starting on the high side to wards low side drag across until level. Materials needed 3 2X4X8' 2 eye bolts with washers length of cable or chain and of course a riding lawn mower or something to pull it with ( good luck )
  • Here's how I did it: Take 4 metal poles (I used 3/4" electrical conduit about 2' long) and pound them in the ground in a square a little bit inside the circumference of the pool. Take some string and tie it off on the first pipe at the height you want the final grade of the pool, Then run it around the next pipe and then the third and forth, but at each, be about an inch or so up the pipe. Then do the diagonals. Then get 4 (or 6) string levels and hang them in the middle of each string. Pound the 2nd pipe down till it's level with the first, then the 3rd till it's level with the 2nd and the 4th till it's level with the 3rd. Go a little at a time. then check the diagonals. now grade the sand till it's just touching the strings everywhere.
That's as level as you can get it without a transit.
  • Well, it depends on the pool. If you plan to have it there a long time you may want to consider removing or adding soil to improve the level. If it is a smaller, temporary pool you can probably get away with using instant paver's or propping up the side that needs it with plywood sheets or something similar. A spirit level will be able to tell you how level the ground is.
  • we put a stake in the center of the pool site and cut a 4x4 piece of wood and spun it around the stake in circles with a level on top of it until the dirt was all level
  • A simple and extremely accurate way to determine if an area is level. Fill bucket with water. Place the bucket next to the area you want to level. Put a clear plastic tube in the bucket with a weight on top of it to hold it there. Suck the end of the tube and put the and allow it to siphon until it is full of water with no air bubbles. As soon as all the bubbles are out of the tube pick it up and you will note that the water level in the tube is the same as the water level in the bucket. No mater where you take the tube the level will stay the same making a perfect reference point for leveling the pool. In other words the level of the sand should always be the same distance down from the top of the water in the tube.

Level Ground is a Must For Above Ground Pools.You should determine were the pool will be located and always find the lowest level in that area and remove dirt to match that level. If you always dig down to the hard ground before assembling an above ground pool, you will 99.9% of the time never have to worry about settling or shifting in the wall or legs that support the wall. Always for extra peace of mind put cement blocks under each leg brace. Get ground level, layout your bottom tract and mark each footer, then dig out under that marked area making the top of the footer block level with the rest of the already leveled ground. If you will take the extra time to prepare the base of pool wall support, everything else will be a breeze putting together.

Is pebbletech or quartz better for the pool surface?

The only advantage to quartz over standard pebles is that quartz does not impart any hardness to the water. However, this is mute point compared to the evaporation that could more than double the hardness readings every season. So choose the color stone you like and enjoy your swim.

Personally, I do not like the original pebble products, as they are rough on your feet. Also, it is difficult to get a tight seal around light and returns. Therefore, you lose small amounts of water there.

Can you empty and then refill your dirty gunite pool?

* Yes, you can drain it. DO NOT leave it empty, however, but refill promptly. If the pool is empty and there is a lot of water in the ground soil, it could cause the pool to float and crack. == == * I have had this house for 4 years and have drained my gunite pool every spring, acid-washed it and refilled it. So far no problems. It does need resurfacing, but not because of what we did. It needed that when we bought the house. I understand that the cost of that is about $10,000. Which means... it might rather be a pond, or a cemented area with an above-ground pool.

* Pools should not be drained completely unless the water table is low. Otherwise water table pressure can damage an empty pool. I never drain my in-ground pool more than 18" below the deck, and keep chlorine tablets in floaters in the pool all winter, which cuts down on brackishness. Removing cover & cleaning in spring just means brushing & vacuuming everything to the filter, then backwash. Sparkling water in one or two days.

* When I lived in Texas, people with this problem installed plastic liners. Some of the ones I saw looked like a tiled pool.

Stop itching skin from a fiberglass pool?

All fiberglass has a final coating of gel coat, it could be marine gel coat, tooling gel coat, or swimming pool gel coat. Typically, swimming pool gel coat will last about 20 years before it loses effectivness. At that point, algae becomes able to "cling", the surface begins to stain, and the actual fiberglass becomes evident to swimmers, causing scratches. There is only one solution, lightly sand off the remaining gel coat, wash down the pool, apply one coat of vinyl ester resin, and roll-on 3 coats of swimming pool gel coat. The pool will be as good as new for another 20 years, provided the pool is properly cared for.

Will an above ground pool liner stretch?

Of course but not by very much. A thick liner can be stretched to seven or eight feet down if you'd like one end to be deeper. Discuss it with your building contractor.

You also have to be careful about the wall collapsing if you go to deep. It's a problem that we're running into more and more.

As the Installation and Service Manager at Abovegroundpros.com, the overall price for you to install a above ground pool yourself should only run you around 200$ 3 to 4 friends who dont mind doing work, maybe some pizza and beer for them and a couple of days to do the job.

We, as an above ground pool installation company, charge anywhere from $775 for a 15foot round to $1895 for a 21'x42' oval. These pools are made for the home owner to be able to install themselves. There are also videos out on you tube or at our web site that can help you in the process of doing it your self. It really is worth it to have the pleasure of your own little vacation spot in your back yard.

What is the recommended slope for drain pipe carrying excess rain water from pool and deck around pool?

Since you are dealing with rainwater runoff, you want to refer to Table 1106.3 "Size of Horizontal Storm Drainage Piping" from the International Plumbing Code along with any local amendments This code will allow you to use the maximum slope you have available at your site and this can reduce the required drain pipe size and cost. For example: Let's assume your pool deck area is 5 feet above and 100 ft from the street gutter. Allowing 1 ft for a drain grate and elbow under your deck, you have 4 ft of elevation left to use over the 100 ft run to the street; this is very close to 1/2 inch per ft slope. To determine the drain pipe size required, we need to know how large an area will be drained. Let's assume your deck and pool area is 50 ft by 75 ft which is 3,750 sq ft but you also have roof area of 1,250 sq ft (horizontal projection only) that also drains onto your deck, bringing the total area to be drained up to 5000 sq ft. The next step is to determine the "Maximum Probable Rainfall Rate" for your location. In the US this information is typically available from the National Weather Service. For example, the East Coast area including Philadelphia and New York City has a 1 in 100 years probability of having rain falling at about 3 inches per hour. Many areas in Florida have values 50% higher. With this data we can refer to Table 1106.3 and find the column for 3 inch per hour rainfall rate. Reading down the column we can see the areas that can be drained for various pipe sizes and slopes. At a low 1/8 inch per ft slope a 6 inch drain line would be required; at 1/4 inch per ft slope a 5 inch line (uncommon size) would be required and finally at 1/2 inch per ft slope a 4 inch drain line would be adequate. Note: If you used a commonly available drain line size of 3 inch, this will adequately drain only 1,096 sq ft when sloped at 1/8 inch per foot (1,546 sq ft when sloped at 1/4 inch per foot or 2,295 sq ft when sloped at 1/2 inch per foot.) During a moderately heavy rain exceeding only 1 inch per hour, this line will allow water to accumulate in the above example and flood the pool deck; perhaps backing up into the house.

Is a gunite or vinyl pool better?

Gunite Swimming Pools are the best type of swimming pool out there, provided that the pool is correctly built they can be installed anywhere in the world without any damage being done to them. As far as servicing of the pool standard service applies e.i. brushing vacuuming chemically treating. And if the necessary care is taken a gunite can last you 20 + years.

Vinyl Liner pools also have there place in the swimming pool market place, they are typically cheaper and quicker to install but on the down side there isn't much customization you can do to them. And to replace a liner can run you anywhere between 3 to 5 thousand dollars.

That brings us to fiberglass AKA Bathtub in the ground ( that's all i can say about that.

What chemicals are used to start up a pool while filling?

First off, test the water going into the pool to determine its "native" pH, chlorine level (municipal water usually has trace amounts), its alkalinity (its resistance to swings in the pH), & its calcium hardness. pH/alkalinity is first. Get the pH balanced, then add chlorine - liquid bleach is an excellent shock treatment, also get some floater dispensers and plop some trichlor pucks or sticks in there. I recommend getting a Taylor test kit (pricey but critically accurate) for use once or twice a month, and a cheap little kit for daily use. I use borax (20 Mule Team at grocery store) for alkalinity issues, baking soda (also grocery store) for pH UP and muriatic acid (hardware stores) for pH down. Learning your waters native alk & pH is 3/4 the battle. Then just keep it chlorinated to kill the beasties. When you are adding new water or filling for the first time you should first add your metal out or metal preventer which ever is in your area to prevent staining,second adjust your alkalinity(sodium bicarbonate for up and acid for down) to between 80 120 ppm. Three adjust your(sodium carbonate up and acid down) PH 7.2-7.5 24 hours after this is done you can add your Chlorine 1.0 to 5.0 ppm 3.0 being ideal in a pool.Once a week use a non-chlorine shock to keep water sparkling.

The Difference Between

What is the difference between a gunite and liner pool?

Dear Theresa, there are a lot of advantages for those who appreciate innovation and comfort. This kind of pools are a new technology mostly in steel and concrete structure with vinyl liner in different qualities. The liner has better behaviour with high temperature changes,the pool structure is auto-portable this means that a soil movement won't afect it, it's faster set up, the liner is easier to clean, the liner is easier and cheaper to repair and also replaceable (new pool! new design!), liner is more comfortable for the step, and you won't think in fixing ceramic tiles or painting the pool every year,... The selection of your pool should also take in consideration the right equipment for the volume of your pool (heart of the pool). Good luck! Xavier

Gunites are nice because of the "free-form" designs that can be generated. They are solid vessel structures made of a reinforced steel cage sprayed with high pressure gunite, then coated with plaster, or tile, or combination of both. They're great in hot wether areas such as Arizona, Texas and California.

However, as mentioned in the previous answer, todays vinyl liner pools are more agile when exposed to extreme weather fluctuations. Vinyl liner pools have developed a bad rap over the years due to poor materials, or craftmanship, of many kits in the early years (70's and early 80's). But, technology has made its mark on today's vinyl pool kits. You can get walls made of high-grade galvanized steel or thick, honey-combed polymer walls that are strong enough to handle the pressure of a Hummer rolling over them. Todays floors are usually made of vermiculite (an oatmeal-like aggregate) mixed with portland cement. Suggestion: opt for dual-track aluminum coping. The lower track for the liner to snap into, and the upper track made for optional fiber-optic lighting. Even if you don't want the lighting right away, you'll have the receiver for it pre-installed incase you want it in the future.

The above answer has some incorrect information in it. The Polymer, honey-combed, pool walls are NOT strong enough to withstand a Hummer driving over it. Polymer (structural foam) panels are about as strong as anything else made out of plastic.. that's what they are... plastic. If the above information is true, I'd love to see a video of it.
