Giggles asked: Porbably 80 yr old pond, came with house. Has a crack, not too far down, think I can seal with hydrolic, waterproof patch compound. Want to seal pond with something that isn’t harmful, in case I want to add fish later or if neighborhood animals sneak in and drink. Pipe to resevoir (has a waterfall) comes out near the bottom, so a liner would need to be punctured there. Also because of the wall at the waterfall, and at the bridge (all one piece with the pond) there would be no where for the liner to go, ie just stick up in those 3 areas, so I think the liner would probably be a bad idea. Any products mentioned in searches, I can’t find, or are $100 or more.
Seen acrylic concrete sealers, doesnt say if ok for ponds though. Also one search doesn’t work well. Have HD and Lowes nearby, but no one there knows.
Pond: 14 ft long kidney shaped, 1.5 ft deep, 1.5 ft wide up to waterfall area, then expands to 2 1/4 ft deep and 4 feet wide. Approx 350 gallons.
Thanks!
