HOME › VOID FILLING & SOIL STABILIZATION
Sometimes the concrete hasn't dropped yet — but the ground under it is already gone. Erosion, plumbing leaks and poor compaction carve out voids that leave slabs bridging over empty space until, one day, they crack and fall. Jack It Up fills those voids and stabilizes weak soil with structural polyurethane foam, stopping settlement before it starts.
North Texas clay shrinks in drought and erodes in downpours. Add a leaking irrigation line, a downspout dumping at a slab edge, or builder backfill that never compacted, and water quietly carries the supporting soil away — leaving a cavity you can sometimes hear as a hollow thud underfoot.
Our polyurethane expands to fill every contour of the cavity, then cures into a rigid, waterproof structure that supports thousands of pounds per square foot. It won't wash away like soil or shrink like cement slurry — the void stays filled.
Void filling is the cheapest concrete repair there is, because you're preventing the damage instead of fixing it. If a slab sounds hollow, shows early hairline cracks, or sits near a known leak or washout, an inspection now can save a full lift later.
Hollow sounds when you tap or walk on the slab, hairline cracking, water disappearing at a slab edge, or visible washout nearby are the classic signs. We confirm on-site during the free estimate.
Yes — cured structural polyurethane supports loads far beyond residential requirements, which is why the same material is used under highways and warehouse floors.
Fix the leak first, then we fill the washout and stabilize the soil. We're happy to coordinate timing with your plumber.
