Crushed Granite For Pool Base

Can I use decomposed granite? Is it as good a low spot filler as crushed granite? Also, after I machine plate tamp my pool site and then it rains a few times, will the rain mess up my plate tamping work? (12' ABG site)


Hi Elliot. The decomposed granite should work just as well as the crushed granite, they are very similar. Rain is great for further packing the granite, the more the better. It's always good to do a final grade just before the pool installation, but no, the rain should not hurt the packed pool base.

Doing something like this around the outer edge of the pool is a good idea also, especially since you already have the granite. This is a big help for keeping the ground solid during the rainy seasons.
