I have a sinking problem with my pool too. The technician says the way to fix it is to drill deep holes around the sinking side and put cement in to support the pool. It is a big job. Takes a couple days.
Pool sinking?
Is the pool sinking The wall of the pool and coping are one unit, the concrete deck is also a unit, they move independent of each other, with a caulk joint between each. That joint must be maintained. Your pool pro has the right stuff. You wont find home caulk at the DEPOT.
Yes I have seen well over 6" inches of change and in
very cold spells especially in the wet years on pools, generally they go back into shape, but caulk maintenance is key. The deck is moving usually gives the illusion of the pool sinking. getapool.com goood swimming take care
I have recently spoken to a guy who did just that and the job that lasted him for 20 years and then he only had to replace the liner the pool frame was still in good order. he used a powder coated zincalume above ground pool.
Basically you dig a hole just big enough for the pool. if the ground is sloped let the pool stick out of the ground on the low side. level the bottom of the hole with washed river sand don't use brickies loam as that stuff gets to hard. now build the pool inside the hole setup the Plumbing and fill it with water. You will now have a gap around the outside of the pool that will have to be filled with a sand cement mixture of 10 to 1.
First, you need to find and fix the leak that is causing the deck to heave.
It seems to me that what you would have to do is much more work than simply installing the pool the way it was meant to be installed-- on the ground and not in it.
drain the water out!
by not swimming
Get a plug.
You first of all have to find out what is causing the slab to heave. If you fix the slab then within a two year period you will be redoing the slab again. You may have a leak in the plumbing of the pool or a leak in the house plumbing or to the garden hose. Fix all the leaks and then replace the slab.
A 16' x 8' by 4" slab requires 3.56 cubic yards of cement.
A 40x60x6in slab requires 44.44 cubic yards of cement.
3.95 cubic yards of cement are needed for a slab that size.
one yard of cement will make a 8 x 10 square foot slab at 4 inches thick, that's 80 sq. feet per yard of cement at 4 inches thick.
8.64 cubic yards of cement.
Sounds like a broken line under the slab
About 24 cubic yards of cement is required for a slab that size.
A 40'x40'x6" slab requires 29.63 cubic yards of cement.
Tell me, what are the bathers going to do to when they walk barefooted over this crushed stone to get to or from the pool???? If the crushed stone is going to be under the pavers - then how do you intend to keep the water from getting to the sub-grade. You probably will want to have a solid cement deck around your pool. Rain water, melted snow and ice, splash out from the pool and or an overflowing pool are not good for the sub-grade around your pool. All the above will cause the pavers to move, shift, become uneven thus causing a safety hazard (tripping). And how are you going to keep the weeds down between the paver?. They will have to be sprayed with a toxic chemical which will get airborne and collect on the pool surface. Depending on what type of toxic mix you use it can be an oily mess for the swimmers and the filtration. Now, are you willing to let children or for that matter adults swim under those conditions? After re-reading the question -- why would you pour a slab of cement then put crushed stone over that? Incorrect wording of the question causes confusion as to what your question is really asking.
You will need 6.17 cubic yards of cement.
9.3 cubic yards of cement is required for this slab.
