Water keeps getting behind 2 year old liner…

[Tomwk196]

Our original pool liner was replaced 2 years ago. We had it for 14 years with no real issues. The only thing was that we could feel subtle bumps behind it which was apparently from surface rust on the galvanized walls that developed over time.

We decided to have our concrete removed and replaced with pavers along with a new liner. The company that installed the new liner recommended installing foam padding on the walls as it would make for a better feel but would also act as a buffer to ensure any surface rust spots that developed over time wouldn’t puncture the liner. They also scraped our old walls clean and sprayed a rustoleum coating prior to the foam. Now we have had a few ongoing issues with groundwater getting behind the liner. The liner stays in the track but you can definitely feel the water bubbles at times. It is not always in the same spot and usually goes away by itself over time, however we never had this issue before? The only thing really different is that we added the foam… and thoughts or suggestions with this? We live in NJ and have had more rain than usual. I do not believe there is a leak in the liner. Thanks!

Your concrete that you removed kept water from getting into the ground around the pool.

I suspect the pavers you installed are allowing water in between the stones to get behind the liner.

It is not your change to foam, it is your removal of the concrete around the pool coupled with the amount of rain we have had this year that has saturated the ground around your pool.

That definitely makes sense… I may have to look into some kind of better drainage system. Never thought of that during the paver install because I never had the problem before. Thank you

If your pavers were set on sand on a concrete slab the water is getting under the paver and once it gets to the slab it has no where to go. The slab should have some holes in it to drain water (there may not be any, or enough or in the wrong areas.). The slab should also be pitched to shed water away from the pool. If this is how you pavers were installed, in a low area away from the pool, pull up some pavers and put a hole in the slabs, fill with gravel and put silt fabric over it and reset the paver.
