Soil Stabilization · San Diego, CA

Soil Stabilization in San Diego, CA.

Soil Stabilization for San Diego homes, done by licensed San Diego County technicians. When the soil itself is the problem, repairing the foundation alone just delays the next failure. Soil stabilization addresses uncompacted fill, expansive clay, washout voids, and weak bearing strata directly.

San Diego: Central San Diego housing stock spans 1920s craftsman bungalows on raised post-and-pier through 1980s slab-on-grade tracts. San Diego foundation work splits between cripple wall and post-and-pier rebuilds in older homes and slab or perimeter underpinning in newer ones. Plumbing-leak voids under slabs are a frequent driver here.

What soils are most common in San Diego County?

We see expansive clays inland (especially east county and parts of inland north county), decomposed granite over bedrock in the foothills, alluvial fill in valleys and creek beds, and uncompacted urban fill on lots that were graded for development. Coastal terraces are usually stable. Hillside lots are the highest-risk class because of slope creep and drainage.

Will polyurethane lift my whole house?

Polyurethane will lift slabs and pavement effectively up to about 1.5 inches. It is not the right tool for lifting a structural footing carrying full house load; for that we use helical or push piers. Polyurethane shines at filling voids and lifting interior slab sections.
