Travel access is the longest variable in scheduling.. We account for local conditions in every job.
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.
