Slab Repair in Rainbow, CA.
Slab Repair for Rainbow 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 North County Inland San Diego?
Inland slab settlement often follows expansive clay shrinkage. Polyurethane jacking is the default fix for interior settlement; perimeter requires underpinning.

How does Rainbow's climate affect this service?
Rainbow is rural ranch country in far North County with large-parcel properties on well water and septic. Hillside settlement, post-wildfire slope concerns, and aging rural foundation stock drive the standard repair scope. Travel time is a real schedule factor.. Inland slab settlement often follows expansive clay shrinkage.
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.
