Bay Area Underpinning Napa, CA – Other Services Offered

Foundation Movement Repair

For homes located on a hillside, one of the most common issues faced is foundation movement. This is usually indicated by signs like sloping floors, problems opening doors and windows, drywall cracks, etc.

Drilled concrete piers are an excellent solution to repair foundation movement and settling foundations. They are also suitable for building a deep foundation system for new construction projects.

Uneven Concrete Repair

Uneven concrete surfaces around your home can create trip hazards that can cause serious injuries to both residents and visitors. If someone gets hurt, you could find yourself facing an expensive lawsuit.

Polyurethane foam injection is perfect for lifting sunken or uneven concrete. Dime-sized holes are drilled into the affected concrete and then the foam is injected underneath the slab. The foam rapidly expands to fill the void, thereby raising the slab. This is a minimally-invasive procedure and your concrete surface will be ready to use within minutes.

Bay Area Underpinning is OUTSTANDING!! Cody, Andrew, Francisco, David and their underpinning and concrete teams did exceptional work installing underpinnings to stabilize our house, then replacing the concrete patio that had to be removed to do the stabilization. Everyone on the teams were efficient, courteous, highly skilled, and thorough. I cannot recommend Bay Area Underpinning highly enough- through each step of the process, from the initial assessment and work quote, to the work and follow-up itself, the staff and crews of Bay Area Underpinning ensured that I was informed, reassured, and we’ll take care of. They were thoughtful about doing their work efficiently and cleaning up after the work was completed. I cannot recommend them highly enough!
