Bay Area Underpinning – Other Services Offered

Concrete Lifting with Poly Foam Injection

The concrete slabs around your home can settle for different reasons including poor site conditions, poor compaction, poor drainage, and invasive tree roots. Whatever the cause of the problem, uneven concrete needs to be quickly repaired and releveled to prevent serious injuries.

First, small 5/8” holes will be drilled into the affected concrete and then the polyurethane foam will be injected underneath the slab. The foam expands to fill the voids and this raises and relevels the sunken concrete. Poly foam injection is a quick, minimally-invasive procedure, and the concrete floors will be ready to bear loads within minutes.

Partial Foundation Replacement

The good news is that most foundations can be repaired. However, every now and then the best option is to partially replace a foundation. Our foundation repair experts in Pleasanton, CA can perform the partial foundation replacement quickly and with minimal disturbance to the occupants.

I can’t praise Bay Area Underpinning enough! Everything from their support team, to their customer service, and the quality of their work has surpassed my expectations. I’ve used other foundations companies in the past and they weren’t great for many reasons – Bay Area Underpinning has none of the challenges I’ve experienced elsewhere, and massive positive upsides! Would highly recommend!

We used BAU to install piers and screw jacks to level our home. Really pleased with the entire process. The communication was stellar and the foreman made sure we understood each step as it was happening. The whole crew was professional, polite, punctual, and very neat. Each day they left the job site nice and tidy. The overall result is amazing. Our floors are level and the house looks great. Would highly recommend for any foundation/leveling needs.

Bay Area Underpinning is THE company to use for foundation work. Aaron, and his crew, were incredibly professional from start to finish. The team kept the work space clean and tidy, communicated well, and updated me as timelines were solidified. They were always on time and ready to maximize their output for the day. I would recommend them in a heartbeat.
