Trying to do a make-shift repair to buy us a few more days before we can replace the liner. Our above ground pool sits on a bed of sand...we have a hole in bottom, right at the base of the side that started out the size of a tennis ball, and is probably now softball size (don't ask!). We have about 3 patches covering the hole, then a larger piece of liner glued down over that. We have slowed the leak (gush) down to about 1/2" over 24 hours. The sand has washed away from under the hole, so there is a 'caved in' area under the hole.
Now, on the outside of the pool there is a pool of water that has formed from the slow leak. I can see a gap underneath the pool where one could stick their hand underneath and touch the hole covered in patch. Here is my question: Does anyone have any ideas as to what we might be able to place 'underneath' the hole, to help seal from the underside also? My husband wondered about expanding insulation in the can, but we didn't know if that would even work under water! We are grasping at straws here to keep it going till the weekend.
Any ideas would be more than welcome! Thanks!
