Base Prep On Hard Clay Soil
(San Diego, CA )
Hi, I'm building a 15' x 36" round pool on very hard clay. My yard is 2-3 inches out of level, I've read that this is too much.
I plan on renting a sod cutter and removing my nasty-weedy lawn and leveling it out. It won't be smooth due to the nature of my hard soil, so I was thinking of getting the masonry sand, and then a Gorilla liner over that.
But I've read here another user sent the Gorilla pad back and instead used a foam pad of some sort. What is this foam pad called and where can I buy one?
Is it really better than just doing the Gorilla liner over sand?
What I would not do is level with sand. I normally use the sod cutter and start cutting into the ground once the sod has been removed. If this is not possible I would order something like crushed granite and level and pack the area. I would then put down a couple of inches of sand.
The problem with the Gorilla pad is that it is hard to get smooth and is paper thin once you have a pool full of water over it. There are several different foam pad made to fit your pool, Gladden makes a good one. You could also go to Home Depot and buy 4' x 8' x 1" sheets of foam, these make a nice pool base.
