Soil Stabilization in Bonita, CA.

- Compaction grouting for densification of loose fill
- Coordination with geotechnical engineer for soils report when required
- Pre and post density testing where specified
- Sub-slab moisture barrier installation under new pours
- Re-leveling of slab sections lifted by stabilization

We account for local conditions in every job.
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.
Will polyurethane lift my whole house?
5 inches. Polyurethane shines at filling voids and lifting interior slab sections.
