I purchased my pool from The Pool Factory. The installation instructions says to put down rock dust around the outer perimeter 2 feet. I have called TPF and explained that my ground is solid, Va red clay. Do you experts think I should still do the rock dust? Of course I’ll be putting pavers down for all my uprights, 2 for the buttress front and back. I’m almost level within 1/2 all away around and can’t wait to get this thing up and going. Wish it would stop raining.
