How can we fix a leak in the ground under our inground swimming pool?

Question

We are replacing the liner on our inground swimming pool and when we took out the old liner we discover the concrete in the bootom had chipped away now we have a few small slow leaks in the very bottom of the deep end. Have tried to fill it with hydraulic cement with no luck is there anything else that I can try to plug the hole while water is still seeping through

Answer 1

The bottom material ( likely a grout or vermic mix) isn't meant to be water proof. That's what your liner is for. Nor should you worry about a little water coming in, so long as you have it mostly out just prior to hanging the new liner.

What you DO need to be concerned about is the smoothness of your parging (the repair). Hydraulic cement cures a little rough, but can be used if this is a spot that ground water is springing up and normal portland cement won't do the trick. It may take a few applications to slow it down, but you don't have to completely eliminate that water coming in.

Answer 2

try cauck (k**k) its a water resistant jelly that when hardened can bend and tiwst without breakage and is usualy used in bathroom liners. go look sometime.

lowes, home depot, walgreens, walmart
