Uneven Concrete Repair

The concrete surfaces around your home can settle for many reasons, including poor compaction, poor drainage, poor site conditions, and more. In California, uneven concrete slabs are often caused by the expansion and contraction of clay-rich soil due to moisture.

To relevel uneven concrete, foundation repair experts in San Mateo, CA, from Bay Area Underpinning use poly foam injection. This is a simple and minimally invasive procedure, which involves the following steps:

  • Small 5/8” holes are drilled in the affected concrete.
  • Polyurethane foam is injected through ports placed in the drilled holes.
  • The foam flows beneath the concrete and starts to react, filling the void and lifting the slab.

Poly foam injection restores your affected concrete slab to its original position, eliminating trip hazards.

Drilled Concrete Foundation Piers

If your home is located on a hillside, there are a few problems you could be facing, like difficulty opening doors and windows, the formation of small cracks in your drywall, and foundation movement. If your problem is foundation movement, we can stabilize it using drilled, cast-in-place concrete foundation piers.

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!
