Foundation Repair for Lasting Stability

Foundation problems rarely improve on their own. Cracks, settling, and floor gaps can worsen over time, making early action important. Our team specializes in identifying the root cause and designing a permanent fix that restores your home’s strength and stability.

We offer several proven foundation repair solutions:

Steel Pier Systems: Push or helical piers transfer the weight of your home to solid, load-bearing soil.
Crawl Space Jacks: Relevel floors and strengthen sagging joists.
Wall Anchors and Braces: Prevent further inward movement of basement or retaining walls.
Concrete Lifting with PolyLevel®: Raise and stabilize sunken slabs quickly and precisely.

Each repair starts with a free inspection. We’ll assess your foundation, show you the signs of movement, and explain your options in simple terms.

Concrete Leveling and Surface Repair

Uneven concrete isn’t just an eyesore; it can also be dangerous. Sinking driveways, cracked walkways, or tilting patios create tripping hazards and drainage problems. We restore these surfaces using PolyLevel®, a high-density expanding foam that provides long-term support without adding weight to the soil.

Key advantages of PolyLevel® concrete repair:

Restores safety by removing trip hazards
Cures quickly, allowing normal use within hours
Fills hidden voids and stabilizes the base
Won’t erode or wash away over time

We also apply crack sealants that keep water from seeping below the surface and causing future settlement. The result is a clean, safe, and level surface that lasts for years.

Crawl Space Encapsulation and Moisture Control

A damp crawl space can quietly damage your home’s foundation and air quality. Many homes in the North Bay experience moisture issues due to poor ventilation and ground humidity. We specialize in crawl space encapsulation systems that protect your home from moisture-related damage.

Our crawl space services include:

Vapor Barrier Installation: Prevents ground moisture from rising into your home.
Drainage and Sump Systems: Keeps standing water out of your crawl space.
Dehumidifiers: Controls humidity and prevents mold growth.
Structural Reinforcement: Strengthens joists and beams affected by moisture or rot.

By sealing and protecting this area, you’ll improve your home’s energy efficiency, air quality, and structural integrity.

A Smarter Approach to Home Protection

At Foundation Repair of CA, we don’t offer one-size-fits-all fixes. Every home we inspect has different soil conditions, foundation types, and stress points. That’s why our team tailors each solution to fit your exact needs. We take the time to walk you through our process, from inspection to installation, so you know exactly what to expect.

We use industry-leading technology to assess soil movement, measure wall deflection, and test foundation strength. Our goal is simple: to make your home safe, stable, and secure for years to come.
