Foundation Repair
Our foundation repair service addresses cracks, settlement, and water damage using steel reinforcements, epoxy injections, and underpinning techniques. We prioritize structural integrity and long-term durability, ensuring homes remain safe and stable. Clients benefit from personalized solutions backed by 25-year warranties.
Seismic Retrofitting
Seismic retrofitting strengthens buildings against earthquake damage through foundation bolting, cripple wall bracing, and steel frame installations. Our engineers design customized solutions to meet LA's seismic codes, protecting properties from lateral forces while maintaining structural aesthetics.
Soft Story Retrofit
Soft story retrofits reinforce vulnerable ground floors with steel frames and reinforced foundations. We ensure multi-story buildings meet SB 721/SB 326 compliance, reducing collapse risks during earthquakes while preserving original building designs.
Hillside Foundation Repair
Hillside repairs involve caissons, grade beams, and drainage solutions to stabilize foundations on uneven terrain. Our team addresses soil movement and erosion, ensuring structures remain secure on steep slopes with tailored engineering approaches.
Sloping Floor Repair
We correct uneven floors by reinforcing failing piers, installing support beams, and adjusting foundations. This process restores structural balance, prevents further damage, and improves property safety and resale value.
