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.

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!!!

Within a few months of buying our first home, we noticed some troubling signs: bedroom doors swinging open or closed on their own, “bubbles” and creaks in sections of the newly renovated floors, and significant cracks splitting the concrete in our garage. Although two general inspectors assured us that our house was level, we reached out to Bay Area Underpinning (BAU) for a more detailed assessment—and we're so glad we did! Inspector Christopher Murray conducted a meticulous inspection with radar equipment. While technically our house was level, Christopher uncovered that our foundation was sinking by inches in multiple areas, explaining the issues we were experiencing. Though the news and associated repair cost were a bit daunting as new homeowners, Christopher’s knowledge, professionalism, and clear answers to all our questions reassured us that we were in good hands. With confidence, we decided to proceed with BAU for the repair. Fredy Mora and his crew did exceptional work with the demo of the old concrete slabs and the prep for lifting, working quickly and efficiently. Fredy’s positive attitude made the process smooth, and his team was thorough and dedicated from start to finish. A special thank you to our lift project manager, Kevin Gaeden. Kevin was an outstanding communicator, keeping us fully informed and addressing every question promptly. His attentiveness made a huge difference throughout the project, and we felt reassured every step of the way. Esteban Ibarra, a crewmember on the lift team, also did superb work, handling the hands-on details with skill and care. Both Kevin and Esteban even went above and beyond, taking time to fix a jammed bedroom door that had shifted with the house lift. While foundation issues are never easy, we couldn’t have asked for a better team. We’re incredibly grateful to Bay Area Underpinning for their expertise, professionalism, and exceptional service. Thank you, BAU!

Our house is 85 years old and has some cracking on the stucco, so I called for a free inspection to see if the problems were something we need to be concerned about. Daniel, our inspector, was prompt and friendly and explained everything he was doing and seeing as he took measurements and inspected the foundations. He said that while there are things we can do for earthquake retrofitting (and he did recommend a separate company for that if we wanted to do it) our problems were mostly cosmetic and nothing to worry about. He also took his measurements to be scanned in at his office and kept on file so that we can have him back out for another inspection in the future to compare, again, purely at our discretion. He was respectful, friendly, and straightforward and answered all of my questions. I'd definitely recommend them.
