Sand And Patio Blocks

by Paul

Every where on the internet about prepping for above ground pools, I read that I should use masonry sand. Many sites even say I should use patio blocks under each leg. Problem is, my INTEX 16' x 48" pool installation instructions tells me NOT to use either!

They don't even want me to remove the sod. What should I do? I want this pool to be level and to last a few years before I need to take it down.

Hi Paul.

When I install an Intex pool I use a thin layer of sand over a very level base of dirt. The level is very important. I could not see installing over grass because it would be so hard to level it. Patio blocks are useful as a leveling device. When all the blocks are set at the same height you are pretty sure of having a level pool.

Sand Disaster - Intex Pool

Sister-in-law installed an Intex 52" x 16' round ultra frame pool on a sand base over a concrete slab to 1) give a soft bottom - good idea 2) bring base to level (3 inch slope over 16')- bad idea.

She filled the thing with water and after 3 hrs of kids playing one side had dropped down 2". A real problem as the increase weight of the water shifted causing the whole pool to start shifting rapidly. I quickly drained the pool to start over (no major mishap and no one hurt).

So how to level the pool over a concrete pad. My idea is to construct a hexagon frame (about 2 inches larger in diameter than the pool) from 2x6 cut to give a level screed and strapped securely together to hold base material. Use the existing sand and mix in about 5 bags of Portland cement. Screed sand/concrete mix level and compact. Set pool up and fill with water.

Will this work? I would prefer to use crushed granite or aggregate base but she doesn't want to toss the sand out... maybe penny wise but pound foolish?

Hi Sam.

I don't see why this would not work. The big thing is the frame you are building, it will keep the sand from shifting and should keep everything in place. Best of luck.
