Slab Repair in Del Mar, CA.
Slab Repair for Del Mar homes, done by an experienced San Diego County foundation crew. Slab-on-grade is the most common foundation type in San Diego County, and when it moves, the whole house moves with it. Slabs settle when the soil under them shrinks (drought), washes out (plumbing leak), or compresses (uncompacted fill).
Why is slab repair different in Coastal San Diego?
Coastal slab repair often involves plumbing-leak voids, older copper supply lines under slabs in 1960s-70s coastal tracts develop pinhole leaks that wash fines out of the soil. We coordinate with plumbers on the leak repair, then fill voids and re-level.

Salt-corroded rebar and bluff erosion drive most of the village scope.. Coastal slab repair often involves plumbing-leak voids, older copper supply lines under slabs in 1960s-70s coastal tracts develop pinhole leaks that wash fines out of the soil.
Will slab jacking break my flooring?
Modern polyurethane slab jacking is dimensionally precise to about 1/8 inch when the technician is good. Tile and hardwood usually survive lifts up to 1 inch. Larger lifts or older tile (1970s and earlier) often break and need to come up first. We tell you up front when we expect cosmetic damage.
How do I know if it is the slab or the soil?
We do a level survey, then look at the pattern. Settlement at one isolated interior point with the perimeter still level is usually a void under the slab (water washing out fines, a buried trash pit, an old plumbing trench). Settlement at the perimeter is usually soil bearing or expansive clay and needs underpinning, not just jacking.
