How do you know if a foundation issue needs lifting versus piering? A lot of the time, it doesn't need either. Clay soil pulls away from foundation edges as it dries, leaving hollow gaps under the slab that don't require structural work to fix.
Terrell Concrete Lifting fills those voids with expanding foam or slurry, stabilizing the slab edge without the cost or disruption of piering. Foundation void filling is not a replacement for structural repair when a foundation is actually shifting, but it solves the more common problem of soil pulling away underneath.
What's included

FAQs
Foundation Void Filling FAQs
What causes voids to form under a foundation slab in the first place?
Clay soil shrinks as it dries out, especially during hot Texas summers, and pulls away from whatever it's touching. That shrinkage leaves a gap between the soil and the slab, which is the void we're filling.
How do I know if I need void filling versus foundation piering?
Void filling addresses a soil gap under the slab edge, not a shifting or cracking foundation. If you're seeing wall cracks, door frames out of square, or other structural signs, that's a different conversation than a hollow-sounding slab edge. A site visit can tell you which situation you're dealing with.
Is foundation void filling the same as concrete lifting?
It's related but more targeted. Concrete lifting raises a settled slab back to level. Void filling stabilizes a gap that's formed under a slab edge, sometimes without needing to lift the slab at all.
How much does void filling cost?
Pricing depends on how much of the perimeter needs treatment and how many injection points it takes. Smaller sections cost less than filling voids around an entire foundation. A free estimate gives you a real number.
