Doors sticking that used to close fine? Cracks showing up near a foundation wall that weren't there last year? That's often a void, a gap between the slab and the soil underneath, caused by clay shrinking during dry stretches and never fully filling back in.
Foundation void filling injects material into that gap to restore support along the perimeter. Richardson Concrete Lifting treats this as a separate scope from cosmetic leveling, since a void needs filling before any part of the slab is safe to lift or load again.
What's included

Optional: combining void fill with a lift on sections that have also dropped.
Customer prep: note where doors stick, where cracks appear, and any hollow sounds near the foundation line.

Foundation Void Filling FAQs
How do I know if my foundation issue is soil-related or plumbing-related?
Soil-related voids usually show up gradually and track with weather, worse after a dry summer, sometimes better after heavy rain. A plumbing leak under the slab tends to cause a localized wet spot or an unexplained jump in your water bill. If you're unsure, we can rule plumbing in or out before treating the void.
Does homeowners insurance cover concrete lifting?
Most standard policies don't cover settling from soil movement, since it's considered gradual and expected in this region. Some policies do cover damage from a specific event like a plumbing leak. Check your policy details or ask your agent directly, we can't make that call for you.
Is void filling the same as full foundation repair?
No. Void filling addresses the gap between slab and soil. Full foundation repair with piers or beams is a bigger structural scope for issues void filling won't solve. Most homes we see in Richardson need the fill, not the full repair.
How much does foundation void filling cost?
Depends on how much perimeter area needs treating. Small localized voids run less; a full perimeter treatment costs more. We'll give a number after inspecting the slab edge.
