What is a slab foundation?
It is a flat piece (slab) of concrete sitting on compacted soil or stone, usually meaning there is no basement. These generally only appear in areas where the ground does not freeze frequently.

Hello,. My name is Terry and I am a help expert in the building and construction field.. Yes, it is possible to construct a treated lumber foundation. It must however, be co…nstructed and inspected by your local building department. There are minimum specifications that can be obtained from the International Residential Code, International Building Code, Universal Building Code, California Building Code and other codes that are specific to different areas of the country. You must work closely with your building official to determine which code you should be following.. Structural design is the basis for safety and durability in a structure, and should always be completed by a competent individual. In my area we require that licensed design professionals such as structural engineers and architects be involved with most designs.. With wood foundations, moisture and pest deterioration are probably the most significant issues. In some areas, such as California, seismic considerations are also in effect.. It is always best to verify CODE SPECIFIC information with your local Building Official and/or Building Department as local laws and codes do tend to vary from jurisdiction to jurisdiction. . I hope you have found this helpful!. Terry CBO
Here is an estimate from another site. http://en.allexperts.com/q/Building-Homes-Extensions-2333/slab-foundation.htm
There really is no set price for what it costs to pour a foundationslab. This really depends on the size of the area covered?Ã¦andmaterials poured.
\n. \n. \nA slab is cheaper to build than a basement. The basement will give more space but is more likely to leak and more can go wrong.
There are five ways in which a person can dry wet the carpet on aslab foundation. The five ways include sealing gaps, sealing theconcrete, air to air exchange, use of the dehu…midifier, and airconditioning.
Rebar and Post Tension cable (PT) are two entirely different items. Rebar is the static steel bars placed in the concrete while the PT are high tensile strength cables that we…re placed in concrete than stressed under hydraulic jacking to a tension generally around 2500 to 3500 psi. As a result, the situations for repair are different. The exposed rebar can be cleaned and patched through approved methods. However the PT should be looked at by a professional as it is an integral part of the structure and, as mentioned before, is under tensioned stress. If the exposed rebar is in a PT slab, caution should be used and a professional consulted as well, due the rebar being integrated with the PT.
Install fire blocks 48" from floor. Stagger them so that one is 48" to the top and the next is 48" to the bottom (easier to nail them)
There is only one advantage of waffle pod slab construction - reduced cost. The waffle pod slab is no more than a slab of concrete placed on the ground, with polystyrene block…s in a grid pattern within. This results in a system consisting of a slab with a grid of stiffening and edge beams, giving the (reverse) effect of a 'waffle' if viewed from underneath. If construction is to take place on reactive soil, consideration needs to be given to the future maintenance of the slab. There is some requirement to ensure consistency in the landscaping and general treatment of the areas surrounding the slab. Typically, having concrete on one side, for example a driveway, gardens on another side, perhaps gravel on a third side and a timber deck on the fourth side can result in different soil moisture conditions which in turn can lead to structural movement and failure. Of course it is difficult to regulate the area underneath the slab. Builders often advise that consistent landscaping or even a concrete apron around the house is required to ensure reliable performance of the slab, unfortunately this advice is sometimes given when it is too late. Typically, category 1, 2 and sometimes category 3 cracks appear, and when the builder is advised he engages an engineer (usually the engineer who designed the slap) to give an opinion. Invariably, it seems to be the fault of the owner. The problem is that houses commonly have concrete on one side (the driveway) and gardens or lawn on another side, so the question really is, is it acceptable that the slab and foundation material be so fragile? Usually, stable foundation material will be found at a reasonable depth - perhaps 600mm - 1200mm. Home builders should obtain a quote for the price difference between a waffle pod slab and a conventional slab & beam construction, keeping in mind the cost of rectification in a cracking building and the effect on resale value. Builders should advise their clients accordingly and give them the option. At the moment, clients are not given the option, the display homes they are shown are not cracked, the brochures do not warn of the likelihood of cracking, they are not told of the onerous maintenance requirements, and it is not until it is too late that the issue arises.
Use polyethylene sheet membrane. Prior to concrete placing, cover the entire area with a layer of PE sheet membrane extending the perimeter of slab and up against wall for the… depth of concrete.
4 To 6 inches
Hire someone. This is not a do-it-yourself type of project. The contractor will essentially drill holes in the low parts of the foundation and pump a new concrete mixture (alt…hough it is not pure concrete anymore) underneath your current slab, which with enough pressure, will cause it to lift. You will have to have portions of the floor removed (whatever is on top of the slab) to get down to the slab however, so costs can add up quickly, unless you just have carpet everywhere (which is easy to remove and replace).
Floating slab is a type of mat foundation. It consists of a hollow mat formed by a grid of thick reinforced concrete walls between two thick reinforced concrete slabs. The wei…ght of the soil excavated from the ground is equal to the weight of the entire building, so that pressure on the soil is unchanged from the original condition, making the building float on the soil
You could probably find someone to try it, depending on the size of the house (stories), the square footage, and a route by which the house could be moved to the new location.…
you may have a septic system leak or a water main leak
No you don't need a mortar bed. if you have existing cement slab, then all you need to do is make sure to check for uneven spots, cracks and fill them in. You can also use sel…f leveling products like levelQuick. Then your good to tile. You could have cracks later develop in your tile due to slab still settling or soil problems. There's different types of products out there to solve that problem.
without knowing your climate, the best would be a crawl space with a concrete slab.
It all depends on the ground conditions and the load of the building. The is also a little confusion around your terminology as the term 'foundation slab' is legitimate. Ma…ybe you are referring to strip foundation versus raft foundation. There are also basement foundations which will help stiffen the construction of a building and anchor it into the ground.
