Why Is the Concrete on My Pool Deck Uneven?

Your backyard pool should be an area of the home where you go to relax and forget about your problems. It’s a little difficult to do that, however, if you have to constantly watch where you’re going due to uneven concrete. Uneven pool deck concrete is a lot more common than you think and it has nothing to do with the way you care for your property. Uneven concrete slabs in pool decks are the result of the clay bowl effect, which cannot be avoided because of how pools are constructed.

When a pool is being constructed, a hole is dug out the size the pool will be. Once the pool is constructed, the gap between the hole and the pool is filled with soil. In order for soil to be stable, it needs to be compacted. The soil that is used as backfill for the pool, however, is loose, porous, and has many gaps all around. The concrete slabs around the pool rest on top of unstable soil that shrinks, expands, and shifts over the years, which is what causes the settling.

Soil displacement is inevitable, but that doesn’t mean there aren’t any lasting solutions. The settled slab can be lifted back into place using PolyRenewal™. Holes are drilled into the slab and polyurethane foam is injected until there is enough to lift the slab. The foam is dense enough to hold up the slab and, unlike the soil, it does not shift, so the reliability of the material makes it the best concrete lifting solution. After PolyRenewal™, you’ll be able to enjoy your pool deck like you were always meant to.
