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.

Foundation Repair of CA now offers SealantPro and NexusPro. In just one clean application, SealantPro guards against oil, gasoline, water, other liquids, and debris. SealantPro shields your concrete from the elements and triples its lifespan. We also now offer NexusPro, the extremely dependable and longlasting solution to cracks and joints in your concrete. Ensure that your concrete is beautiful and safe for years to come with SealantPro and NexusPro!

Seismic & Earthquake Retrofitting, Reinforcement & Repair in Castro Valley

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, driveways and sidewalks.

Due to the recent storms we have found our carpet was wet and found mold on the carpet tack strips as well as the back of the carpet. This is in an added sunroom that was once a patio. We can see cracks in the concrete on the floor. We don't know how the water is getting in but think it is through these cracks.
