problems with pool krete

[minermom]

Last June, we had a 18 x38 doughboy pool installed with a 7ft. deep end. After a frustrating first few weeks, finally had pool up and running in July. Now this year we have noticed a sunken "path" in the shallow end of our pool, like maybe ants or a mole. Our contractor installed pool krete and immediately sunk the liner. Anyone know if that is how it is supposed to be done? I contacted him because we were still in our one year warranty, and he said he can't control the moles or things under the pool krete. I thought that once the pool krete set, that is was hard enough to prevent anything coming up from beneath. Any ideas or suggestions.
Thanks,
Minermom

Nothing should come up through the base but if the ground shifts underneath it will settle. Does the sunk area run horizontal to the side braces a couple of feet away from the wall? This is a common place for the ground to settle.

Best of luck, Dennis

Yes, and it looks like a place something has tunneled. I guess there's no way to fix it until we replace the liner. Is that the way to do pool krete, to not let it harden first, then sink the liner?
Thanks for your help

Hi, it sounds like the ground settled on the outer edge of the pressure plates. That is fairly common. That probably would have happened no matter how firm the pool krete was. It is possible to drain the pool, just not into the deep area, repair and refill ASAP. I have done that. Or you could wait until your first liner change.

As for how long to let the stuff dry. I have very little knowledge there. I could not say for sure if that would have made a difference or not.

Hope it works out OK, Dennis

Miner mom,
I have two sets of friends who had pools installed, both w/ quick krete. Both stated that the installers (from the pool place in which they bought) let the q.k dry 24 hours prior to coming back and doing the linerand fill.
Sorry
