PolyLevel® Concrete Lifting & Leveling

PolyLevel® is sometimes mistakenly referred to as slab jacking. This concrete leveling product is a two-part foam engineered to expand immediately upon injection beneath a settled slab. Injection holes are much smaller than those required for mud jacking. In action, PolyLevel® expands to many times its original volume, forcing the sunken concrete back to its original level. Within a matter of minutes, the expanded polymer hardens and reaches 90% or more of its final strength. This makes it possible for the restored surface to regain full functionality right away.

Seismic & Earthquake Retrofitting, Reinforcement & Repair in Sonoma

Do you live in an area that's prone to earthquakes? Don't take chances with your property. At Foundation Repair of CA, we specialize in stabilizing homes and businesses throughout Northern California. Earthquake retrofitting, or seismic retrofitting, is the reinforcing of a house or building so that it is less likely to be damaged or separated from its foundation during an earthquake. With earthquake retrofitting in place, you're less likely to face significant damage when a natural disaster occurs.

If an earthquake event has already caused foundation issues we specialize in primary foundation damage repair of all types. Our expertise also includes concrete lifting and leveling of slabs, driveways and sidewalks.

Job Stories From Sonoma County, CA
Two Residents, One Big Foundation Problem

Ms. S and Mr. L weren't a couple, nor were they connected by blood in any way, but because of the duplex that they each owned half of, they were connected by the foundation of their shared home. They were also connected by the settlement their shared foundation had surprised them with. Ms. S and Mr. L decided they needed to come together to find a solution. With their combined efforts, word-of-mouth was what brought Ms. S and Mr. L to Foundation Repair of CA. A neighbor across the street had experienced similar issues with their foundation and eventually told Ms. S and Mr. L that they would recommend FRofCA to anybody who needed a quick and professional solution. With the installation of our Push Pier system, the weakened soil beneath the home that allowed the foundation to slide towards failure was let off the hook as the weight of the home was transferred to stronger, more competent bedrock beneath the visible soil. Two neighbors with walls separating them, came together to find a solution to save their home and Foundation Repair of California was more than happy to have provided them with the answer they so desparately needed.

I am looking for seismic retrofit estimate for our house. Do you offer a free service?
Vicinity of in Sonoma
I have dampness in my crawl space under the house. I would like to put a vapor barrier or plastic to cover the area so the damp smell in the back of the house can be prevented.
