FAQs

Does Bay Area Underpinning fill concrete cracks?

We do not use conventional fillers for concrete cracks. Our approach involves injecting high-density polyurethane foam under concrete to lift and stabilize it. While we do not “repair” concrete cracks, we can often close them when lifting concrete slabs. Contact us to learn more and to schedule a free inspection and estimate.
