East County foundation movement is dominated by drought cycles, post-wildfire slope instability, and uncompacted 1970s tract fill. Alpine helical pier work typically terminates in decomposed granite or weathered bedrock. Drainage retrofit is part of nearly every repair plan here.. East County stabilization on uncompacted 1970s fill uses compaction grouting or polyurethane to densify and bind the existing material in place.

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.
