Fiberglass Crack Repair On Pool Bottom - Best Materials
Posted 07 June 2011 - 08:29 PM
I have a case of where hydrostatic pressure caused the bottom to bow up in the middle going length wise at about a height of 12".
I was able to run a pump and remove most of the water underneath the pool bottom.
Unfortunately the bottom of the walls were pulled in some when the bottom bulge in the middle. Now with the water removed from under the bottom, and the next day the bottom sunk down except at the high point of the bulge.
Now I have a sharp peak going down the middle of the pool and a major crack (the fiberglass is snapped/split) following the peak. The fiberglass is not separated in the crack, but seems slightly splintered.
This means during the dry season of July and August I will have to drain the pool remove the plug for the bottom drain and start the repair.
I have done fiberglass repair on some plastic shells (not pools) before and the general supply of fiberglass resin seems very ridge. I would like to know about other fiberglass resin that has some flexibility.
Is there a way to force the bottom of the side walls that slipped in a few inches by going from a sharp curve to a banana curve? Or should I just cut the fiberglass where the sharp peak is at and do stitches with heavy nylon fishing line, then overlay with fiberglass mattes (how many?) to complete the repair into a smooth look.
Thank you for any advice you may share!

While I don't sell pools (I fix them), those shell installers I know all use trucked water and either washed in mason sand or small gravel for back filling during the addition of water, never letting either the backfill or water level difference be more than a foot so there won't be any bowing in or out.
I have fixed nearly every residential pool problem so far. If I can't do it, I know who to call.
