Why Concrete Sinks in North Texas (and How to Stop It for Good)

If you live in Frisco, Plano, Denton, or anywhere across North Dallas, you’ve seen it: driveways that dip, sidewalks that split, patios that pull away from the house. There’s one main culprit — the ground itself.

It’s the clay

North Texas sits on expansive clay soil. When it rains, the clay swells. When it dries out in our long summers, it shrinks and pulls away, leaving voids under your concrete. Over years of swell-and-shrink cycles, slabs lose their support and drop.

Erosion makes it worse

Poor drainage, downspouts, and plumbing leaks wash fine soil out from under slabs, accelerating the settling.

How to stop it for good

You can’t change the clay — but you can stabilize it. Our polyurethane foam fills the voids and binds the loose soil into a water-resistant base, so the slab has solid support again. That’s why a proper foam lift lasts for decades instead of sinking again next season.
