Driveway Void Fill in South Salt Lake, UT

Driveway Void Fill in South Salt Lake, UT

A hollow-sounding driveway can be an early warning sign that something is happening beneath the concrete. This driveway in South Salt Lake hadn’t visibly settled yet, but the dull, hollow sound indicated there was a void underneath the slab, likely caused by soil that had washed away or settled over time. Left untreated, these empty spaces can eventually lead to movement, cracking, or sinking.

Polyfoam Solutions injected high-density polyurethane foam beneath the driveway to fill the void and restore support underneath the concrete. By addressing the problem before the slab had a chance to sink, we helped the homeowner take a proactive approach and potentially avoid a much larger concrete repair down the road.

The takeaway: You don’t always have to wait for concrete to sink before doing something about it. If your driveway sounds hollow, has gaps along the edges, or shows other signs of soil settlement, it may be worth having it inspected before a small problem turns into a bigger one.
