My self install if so far so good. Walls are set, ring wall poured, sump and drains in, backfilled with 8/9s to about 20", plumbing done and tested. I am ready to either Pool Crete or sand/cement mix the bottom prior to installing the liner. We keep having rain every few days so this is getting difficult to tack myself and miss the rains. Any suggestions? Whould the Pool Crete hold better once it dried? I will need a few days to get the bottom in and am afraid to just use the grout mix if I won't get the liner in immediately. Any suggestions or experiences would be appreciated.
