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.

We recently had foundation work completed. The crew was on time every day and worked hard to keep a very dirty job and their traffic through the house to a minimum. The crew chief, Robert Busch, was amazing. Telling us what was planned for the day, any unforeseen problems, and giving us a recap of what was completed daily. We could not have had a better experience with his communication and hard work. Everyone was respectful and friendly. I also thought that the evaluation and estimate experience was positive. Jim communicated clearly and we never felt that work being suggested was unnecessary. He explained clearly and showed us pictures of what was going on under the house.Hope we never need them again, but would use them in a flash.

I hired BAU to underpin our foundation. After extensive research I learned that BAU does the best work and at reasonable prices. Jordan lead the crew that did the work on our house, and he was a joy to work with and we really trusted him and his team to take care of us. I am really glad we hired BAU, and we are happy to have our hillside home properly secured for the future!
