How do you make gunite?
Gunite, or more properly, "dry process shotcrete", is a cementious product consisting of cement, sand and water. The cement and sand are pumped dry through a series of rubber hoses by compressed air. The water is introduced at the end of the hose in the mixing nozzel and the material is sprayed out of the nozzle at high velocity onto the surface that it is being applied to. Gunite is widely used in the construction of swimming pools where it is sprayed onto the walls and floor to create the pool shell. It can be easily shaped to create steps, benches and other features found in pools. Gunite pros- it can be easily transported to job sites and only what is needed can be mixed, so there is little waste. Gunite cons- One property of gunite is called rebound. This is material that bounces back off the application surface as it is being applied. This material is weak and cannot be used in the structure being built. It must be removed and discarded.
Are concrete or steel walls better for an inground swimming pool?
Steel walls are currently the lowest quality wall for a swimming pool, with the exception of Cyprus wood (if still available). Concrete (not gunite) is superior to any other wall, but a pool with concrete walls generally also has a concrete bottom. In other words, it is a concrete swimming pool. The most popular wall today for vinyl liner pools is fiberglass and, with the possible exception of concrete, is the best possible choice.
What is the purpose of the hydrostatic valve and how do you release the pressure in it and does this valve need cleaning or other regular maintenance?
A hydrostatic relief valve prevents your swimming pool from wanting to become a 'boat'. If the bottom of the pool is below the level of ground-water, and the pool is emptied, the pool would want to float in the underground water. I have actually seen the deep end of a 40ft gunite pool (with no hydrostatic valve) rise out of the ground (by 18") when the pool was emptied for repairs. A hydrosatic valve would have opened (and allowed the underground water to flow into the pool) when the water pressure beneath the pool became greater than the water pressure in the pool. I am not sure if you can manually test the valve, so check with the supplier/pool builder. A hydrostatic relief valve is located in the deepest part of your pool. It may be under the maindrain cover or in its own little box on the bottom of the pool. The purpose of the hydrostatic relief valve is to relieve a build up of pressure if it occurs from underneath the pool. If the water were to be removed with a high water table then the pool may float up out of the graound like a barge. You then have a big problem on your hands. The fhydrostatic relief valve will open allowing the ground water to enter the pool to keep the equalibrium and to relieve built up pressure from underneath the pool. The valve typically does not need any maintenance. However, if the vavle has opened then there is a chance that a tiny particle could get stuck in the seal when the valve closes again. The tiniest particle (which may not even be seen) could allow water to seep out of the pool into the ground. There's a lot of water in the pool and each gallon of water weighs 8.33 pound. A typical residential pool of 20,000 gallons holds water weighing about 166,600 pounds. A commercial pool of approximately 120,000 gallons has water weighing approx. 1 million pounds. Removal of this much weight obviously changes a lot of things. You need to be very careful removing water from a pool. Things to be concerned about are high water table, underground springs, rainy weather, hills behind the pool. Please write if there are any other questions.

FURTHER ANSWER When you find your pool losing water and don't see any obvious place, it may be the hydrostatic valve has lifted and then not seated properly. The valve needs to be flushed by being lifted momentarily. I have done this by donning a mask and with fins and weights swum down, removed the grate, and lifted the valve by hand. If you have never seen such a valve find one in a swimming pool store and see how it works. Also, be sure there is not a lot of trash in the fixture near the valve or again it may not seat. Best to do this with the pump off if the valve is in the drain box or you may get caught by the suction. This can lead to serious death! Paul Delage
Which is less expensive to build a pool with gunite or schockcrete?
Gunite

What was the former name for gunite?
The former name for gunite is shortcrete. The term gunite is used for spraying concrete or mortar in a wet or dry process using a patented gun type applier.
Is gunite considered to be porous or non porous?
Gunite is a type of sprayed concrete, and is basically as porous as concrete is.
How long do you have to wet down a gunite sprayed pool?
Our pool installer told us to wet down our gunite once in the morning and once in the evening for seven full days after the gunite is installed.
What is the better pool Pebble sheen or gunite pools?
Pebble sheen is the finish on the surface of a pool gunite is the cement that a pool is constructed from in other words you can finish a gunite pool with pebble sheen.

building pool myself just want to contract out the gunite job are you interested
What are the benefits of Gunite swimming pools?
Some of the benefits of Gunite swimming pools are extnded warranty and reliability. They are a great brand.
Can you change the shape of a gunite pool?
NO
How do you mix cement to get gunite?
It's a standard concrete mix that only becomes 'Gunite' when blasted from a hose that controls the amount of water.
