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.

1. Call Center ***** – they took the call after 6:00 PM and were extremely professional. Guy on the phone (sorry I didn't write is name down), was so kind and emailed confirmation immediately. 2. Pre-Visit Confirmation ***** – Email, text and phone calls to confirm the time and prep me for the visit. Incredible. Nobody is doing this right these days and BAU absolutely has it nailed down. 3. Estimator ***** – I wish I could offer more than 5 stars. Joe Le Bel is the most professional tradesman I've met in a long time. Others are good too, but Joe is the gold standard. He sat with me to ask what I was concerned about and what was important to my family. Who does that???? Oh yeah, Joe did. So comforting. Joe was professional and respectful of our space. Was careful to be conscientious about where he placed his gear, tools and instruments. Super clean going under the house without tracking dirt and debris back into the house. (The inspectors from HomeGuard could definitely take notes on this!) Then, once Joe finished, he sat down with us and talked us through all the different aspects off his inspection. What an extremely positive interaction. I would 100% recommend BAU and Joe. Can't get any better than this. Thanks BAU for a great culture of excellence. Thanks Joe for being such a good human and professional!
