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.

Do you have cracked concrete? You're in luck! Foundation Repair of CA now offers NexusPro, a silicone-based material specifically engineered to provide flexible and durable protection for the cracks and joints in your concrete. Nexus-Pro withstands harsh weather and UV rays, so it will never crack, bubble, or dry out. We also offer SealantPro, which uses sealing technology to bind to your concrete at the molecular level and extend the lifespan of your concrete by 3-5 times. Keep your concrete looking new for years to come with NexusPro and SealantPro.

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 repair of slabs, pool decks, patios, and driveways.

Job Stories From Sonoma, 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.

Vicinity of Larkin Drive in Sonoma
Shopping for vendor to install crawlspace vapor barrier. Seeking quotes from at least 3 local suppliers. Seeking in-house inspection and estimate.
Vicinity of Crocus Court in Sonoma
We recently purchased and remodeled a home that was originally built in the late 80s...and installed a second sump pump in the crawl space. We had a recent plumbing leak in the crawl space and it was suggested that we arrange to have a vapor barrier installed during mid-to-late January. We are interested in arranging for that installation by a seasoned reputable professional contractor. Thank you...

We would like to have 18 helical anchors installed to anchor a ClearSpan fabric structure. The truss and fabric structure is 160ft long and 45ft wide. The tie down force that we need is at least 4000 lbs per helical. We would like a quote for the purchase of the helicals and the installation of the helicals. Thanks

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.
