How thick is the shotcrete in a pool?
6 inches thick
To be structurally sound, a concrete pool shell should generally be 6 inches thick. Depending on the engineer and the soil condition, it may be more. (On top of that, the plaster interior finish should be at least ⅜ inch thick.)
How thick are shotcrete pool walls?
Typically, concrete walls of inground swimming pool shell should be 6 to 12 inches thick. However, for some projects or in some sections of the pool shell, a builder will make the shell walls thicker. They need to be thicker at the top of a pool form, where the soil exerts greater pressure.
What type of concrete is used for swimming pools?
gunite
The use of gunite or shotcrete is typically your pool builder’s choice.
How do I calculate pool shotcrete?
Multiply the total square feet times the thickness of the floors and walls. For example, if your walls are 300 feet square and 8 inches thick ( 8 inches converted to feet is . 75), multiply 300 times . 75, and you have the total cubic feet of concrete to be poured.
How thick can shotcrete be applied?
There is no stated maximum thickness for shotcrete used in shear walls or any other type of wall. Walls have been successfully placed to a thickness of 36 in. (914 mm) for some time. The two main concerns are the heat of hydration and proper encapsulation of the reinforcing steel.
Can I do shotcrete myself?
DIY shotcrete is achievable for a hobbyist, owner/builder or a contractor. It is all about the speed of delivery you want to accomplish. Before getting started, decide if you want to spray ready mix or site batched shotcrete. For most DIY shotcrete, you will be setting up for site batching/mixing the shotcrete mix.
How thick should a concrete slab be for an above ground pool?
#2 The standard thickness of a concrete patio slab is 4”. For an above ground pool, you can get away with only a 2” thick pour. Concrete is expensive. You can save some money by just making a 2″ thick pour.
Is shotcrete more expensive than concrete?
In addition, shotcrete — while less expensive than poured concrete — is more expensive than gunite. Finally, shotcrete takes a significant amount of time as compared to poured concrete, making it a less than ideal choice for large foundations, structural piers or other large projects.
Is shotcrete stronger than concrete?
What is Shotcrete? Frequently used in underground applications, shotcrete is a wet- or dry-mix concrete that is pneumatically propelled at high velocity through a hose and nozzle. And because the spray application process reduces the water/cement ratio, it’s generally stronger than CIP.
How many yards of concrete do I need for a 20×40 pool?
How much concrete do I need? Order this much concrete, for these standard pool sizes. 12 x 24 – 5 yards, 14 x 28 – 6 yards, 16 x 32 – 7 yards, 18 x 36 – 8 yards and a 20 x 40 – 9 yards.
How do you calculate concrete around a pool?
To determine the area of a round pool or spa, the formula is: 3.14(pi) x R^2(squared). Example: An 8′ spa = 3.14 x 4 x 4 = 50.24 sq. ft. To next determine the volume, multiply the area (50.24) x the average depth (approx.
Is shotcrete better than gunite?
Gunite generally lasts longer and maintains a higher quality than shotcrete. For instance, gunite tends to dry faster than shotcrete, leading to a much smoother surface and avoiding significant cracks from shrinking. Gunite can also withstand up to 9500 psi, a much higher psi than shotcrete.
