    Building on sandy soil


    I've finally ordered a pool (Sharkline Reprieve 15x30) and am now prepping the ground for install. After using a sod cutter to remove grass, I've found the soil underneath is really sandy, almost like being at the beach.

    What I'm wondering is if I need a base material (like crushed limestone) to support the pool? The posts and buttresses (maybe rails also) will be supported with concrete pavers. I plan on using a plate compactor on the soil, so the ground should be somewhat firm.

    Any help is greatly appreciated, thanks!

    I'm dealing with clay n having crushed limestone brought in. If I were you, I'd do the same for your sandy soil. I'm also renting a plate compactor to set it.
    I'd bet you my bikini you'll never get TFP water from a pool store!

    The sand should be fine as long as it's natural and you don't build up with it. If you're concerned about it you can mix some pool-crete in it to stabilize it.
