You are in for a rough ride. We had the same problem every spring here in the notheast. Finally the liner ripped. We had to remove the liner, dig a big crush stone pit, put a sewer pipe in the pit, and run it off to a location at the back of the yard that was lower than the pit. The water comes out of that pipe every spring and the liner does not float. we were lucky due to the lower elevation out back, it allowed us to drain there. I have heard there are special valves that can be installed into certain pools such that if the hydrostatic pressure of the groud water is about to float the liner, the valve will open and let the water escape into the pool. I don't know how well this solution works though.
I don't know what to do once its floating but for people looking to prevent it - installing a french drain. Thanks, The Windsor-Browns
when this happens liner must come if can save good i am from NJ we would pump the water out then i would put rock and daed line this will keep the water down so your liner will not float when the liner gose back in the water will keep it down.try that manny advanced pool and spa service,inc
For our inground pool with what we found to be 3 undergroung springs we had to dig 3-4 foot below the original pool drain and install a sump pump that runs year round.
Make sure the water around the pool is lower than the water in the pool..
The pool liner pad is placed underneath the pool liner to prevent items from cutting through the liner. If the liner is already leaking, the liner pad will not stop the leak.
The sun and the chlorine are the worst things for a liner but there is not much you can do about that try dissolving the chlorine in a bucket of water before adding to pool it does help some but as i said there is not much to stop it.
A Hydrostatic valve is basically a plug that stop water coming down out of the pool, but when the water pressure under the pool gets higher then the pressure in the pool it will let water into the pool from underneath in order to stop the pool from floating in ground water.
You need to throw down a 3 inch layer of pool sand then level it out a put your liner down.
Keep pumping it out as it builds up but don't block it of you may end up with a pool floating up out of the ground.
you have to stop the continued exposure to chlorine. the damage done is done and can not be reversed. put a liner in the pool to stop the leaks, expose the foundation and apply a protective membrane or simply backfill and abandon the pool.
Perhaps it is not a drain but a hydrostatic valve. These are fitted at the bottoms of pools to let ground water that has built up under an empty pool into the pool in order to stop it from floating out of the ground.
It sounds like there is a broken water line under the sand. Perhaps from a sprinker system?
Yes, it can be accomplished. But you would need to install new bead receptor over the existing bead receptor and the old liner should not have any wrinkes. But if the pool bottom surface is in good shape, there is no value to leaving the old liner in. If the bottom surface is bad, then resurfacing the bottom is the best option.
No, it does not stop. They are bound due to gravity.
If you mean can a concrete pool pop up out of the ground then the answer is Yes it can. All you need is an empty or partially empty concrete pool and a lot of ground water around it once the ground water around the outside of the pool builds up enough the pool will start to float. I have seen it happen several times over the years. To avoid this happening most pools have a hydrostatic valve fitted in the bottom of the pool to allow ground water into the pool when there is a build up of water pressure outside the pool it flows into the pool to stop it from floating.
