Soil Stabilization in Rancho Bernardo, CA.
Soil Stabilization for Rancho Bernardo homes, done by an experienced San Diego County foundation crew.

Soil stabilization addresses uncompacted fill, expansive clay, washout voids, and weak bearing strata directly.

Inland stabilization addresses expansive clay directly with chemical grouting where the soils report calls for it. More often the pros we send pair underpinning + drainage and let the clay sit.

What soils are most common in San Diego County?
The pros we send 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.
