Repairing Pool Tile Grout - Above and Below the Water Line


New member

I am have some pool tiles where the grout has come out in a line of tiles near the skimmer basket. Water is slowly leaking out of the pool through this crack so I need to repair it. Does anyone have a recommendation on what product to use to fill this grout line crack that is about 1/4" wide?

Thanks in advance.

I'd drain the water level down below the problem area, clean out the joints and regrout with sanded epoxy grout. It's tougher than a $2 steak, impervious to chemicals and completely cures in a couple hours.

You should be able to find it anywhere that sells tile.

If water is leaking out of the pool I would think you have to fix more than just the missing your shell has a crack that needs filled. Just patching the missing grout would not solve your problem at least in the long term as water will eventually migrate behind the tile again. I think the best course of action here be to remove the tile, fix the crack, replace tile and regrout. I'm no expert so hopefully someone else chimes in for confirmation.
