The immense weight of a full pool surcharges the underlying and surrounding soil significantly more than that of a building foundation, which is designed to spread the load over a wider area. Pools have a lot of weight in a condensed area, so the soil beneath the pool carries a much larger load than the decking and structures around the pool.
For this reason, pools can settle and force the surrounding pool deck down with them. To mitigate this issue, DFS will typically use a slab jacking procedure to raise and re-level the pool deck. There could be numerous reasons to why your pool or pool deck is experiencing differential settlement. This is why it is important to contact DFS to send a qualified engineer to fully investigate the site.

Pools are often constructed near seawalls, which are designed to retain the weight of the soil behind them. Erosion of the supporting soil beneath the pool and pool deck is often attributed to a leaking or cracking seawall. In this case, DFS would employ a permeation grouting technique to seal the leaks, followed by a slab jacking and concrete leveling procedure using our Precision Lift polyurethane injection system.
