North County Inland sits on expansive clay valleys and decomposed-granite foothills. Bonsall settlement is usually drought-driven shrink-swell on clay or hillside slope creep. Repairs almost always pair underpinning with drainage retrofit; either alone is half the answer.. Inland stabilization addresses expansive clay directly with chemical grouting where the soils report calls for it.

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.

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.
