Bay Area Underpinning – Other Services Offered

Foundation Movement Repair Using Drilled Concrete Piers

If your floors seem to be sloping and you live on a hillside, it could be due to movement in your foundation. You might also see drywall cracks and have trouble with doors and windows. At Bay Area Underpinning, our foundation experts in Walnut Creek, CA, can fix this kind of foundation movement using drilled concrete piers.

Drilled concrete piers are a perfect solution for areas with expansive soil, with potential for soil erosion, and where the soil’s upper layer is not very strong. These piers come with several advantages:

  • They can be installed in soil as well as rock
  • The drilled holes can be inspected visually
  • They can be used in expansive soils
  • They are strong and reliable
  • They are capable of supporting large loads

Slabjacking

Slabjacking is used to lift sunken concrete commonly found in driveways, sidewalks, pool decks, and even garage floors. Sunken concrete slabs are a trip hazard. If someone falls, you could find yourself facing a lawsuit. Slabjacking is a minimally-invasive technique that lifts sunken slabs:

  • The process starts by drilling small 5/8” holes into the affected concrete slab.
  • Polyurethane foam is then injected via the holes underneath the slab, where it expands to fill the void and raise the sunken concrete.
  • The drilled holes are then patched, and the area cleaned.
  • In just 15 minutes, once the foam cures, the concrete surface will be ready for vehicular traffic and regular use.

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!

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.

Foreman Andrew is incredible and a leader. We hired BAU to perform a whole house underpinning job from December 2022-March 2023. Our recently purchased 1950's home sat on expansive clay soil and had been settling for decades. The project was a big job and complicated by the winter rains that occurred throughout many days of the project. Andrew was extremely professional, knowledgeable about every aspect of the job and managed the entire project class and skill.He communicates very effectively and is transparent to assuage any concerns that we had on the project. He also shows up earlier than anyone, and works the entire day, rain or shine, in the mud and trenches with his team. This leadership was impressive. Since the completion of our project, he has remained available and came out to make some minor adjustments promptly and free of charge. Without any hesitation, I would entrust BAU to do my foundation work with the demand that Andrew lead the project. Thank you Andrew and your crew for a job well done.
