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.

I called in Bay Area Underpinning for foundation work. They were wonderful answering my many concerns, I received prompt return calls, the work was completed within an appropriate time frame, and the best thing he stayed with the estimate to the dollar. I loved the engineer, time frame, and minimal damage repair. I didn't know how my house was going to respond and even the marble and windows handled well. Unfortunately I didn't get the exact lift I wanted in the office even though they tried their hardest. My advice — call them when the problem first arises and the outcome and the house will lift with ease. I definitely recommend BAU. Because I live on a hill one pillar had to be covered – done. I also had a French drain installed to divert the water which was recommended. Thank you

This company gets a 10 out of 10 from me. From my initial consultation with Rick DeSoto to the work performed by foreman Raul, and his team Jonathan and Demareon, this was the best possible experience in working Bay Area Underpinning for the first time. The crew was professional and adjusted the leveling jacks (and even added a couple as was needed) with care and great attention. Pricing was very reasonable too. I'll never trust any other company to do this type of work at my home. 100% satisfied with the work and my interactions with the crew. A+ work performed = A VERY HAPPY CUSTOMER!!!
