Iím trying to figure out a plan of action before we install another liner to our 100,000 liter sports pool next year.
We CONSTANTLY have issues with high ground water so we are pumping out that water every spring ( a lot of it) and of and on all swimming season.
We pump it out now by removing a small section of the liner and putting in a 2 inch hose attached to a 2 hp pump. (And yes, we watch it every second to be sure we donít tear the liner)
Because the pool builders did not install any kind of weeping tile or dry well/sump system AND the pool is situated in probably the lowest point in the whole property I donít see this problem ever going away.
Needless to say this has shortened the life of the liner because it stretches and creates wrinkles which eventually lead to holes. The vermiculite/concrete base washes away more and more each year, which creates other issues as well.
We have already had to cut holes in the fiberglass stairs and repacked with sand because it had washed away and I can see that being an issue again.
I've included some pics so you can see the lay out of the land around the pool.
So any suggestions/plans of action would be greatly appreciated.
