"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!"

"A fantastic experience from start to finish, BGL transformed our vague intentions into concrete form. We needed a soil and grass lawn converted to a rock garden with undemanding but beautiful flora. An adjacent ramp and slab needed to be replaced to correct their inclines. BGL rapidly produced a striking design and then enacted it rapidly and thoroughly. In addition to the concrete work, stone walkways were placed and a drip irrigation system was installed and integrated."

"I recently contracted with Brothers and Brothers Builders to complete renovations on two bathrooms and expansion of the master bedroom walk in closet. This was my second remodeling project having completed a home rebuild a while ago, so I have prior experience working with contractors. Working with Brother and Brother Builders was just a great experience and the finished work is outstanding. Our Project Manager was Daniel Perez who did an excellent job communicating with us on a regular basis, was immediately accessible by text, staying on top of the project, and fulfilling our visions. He is very knowledge and made several suggestions along the way that really enhanced our design. He has a “can do” attitude. Even into the project I would ask him to do little extras and he always accommodated us with a great smile. Daniel even noticed finished items he did not like and had his crew return to redo the work. He was a delight to work with. The on-site managers, Nick and Oner, were also helpful, professional, and very accommodating. In fact, the whole construction crew was great. The project was completed as per the time line and within the contracted amount, no surprises. With regards to the finished product, we could not be happier. Brother and Brother Builders really provide quality work, attention to detail, customer service, stress less remodeling, all in a timely manner. Their quality of work and professionalism is unmatched. Take it from one who has experience with remodeling projects, I highly recommend Brother and Brother Builders."

Concrete Leveling questions, answered by experts

Polyjacking and mudjacking can both be effective solutions for sinking concrete, but they have key differences. Polyjacking, which uses expanding polyurethane foam, is often considered a better option because the foam is significantly lighter than the cementitious material used for mudjacking. This reduced weight puts less pressure on the underlying soil and lowers the risk of future sinking. Polyjacking is suitable for any sinking concrete slab, while mudjacking is typically only recommended for non-structural concrete, such as sidewalks, patios, pool decks, and driveways. The primary drawback of polyjacking is its cost, which can be up to four times higher than mudjacking—as much as $25 per square foot compared to a maximum of about $6 per square foot for mudjacking.

Polyjacking can be a permanent solution to sunken concrete if you also address the underlying issue—like poor drainage—at the same time. The polyurethane material itself can last as long as or even outlast the concrete you’re lifting it with. Your sunken concrete issue will likely return if you don’t couple polyjacking with proper drainage to prevent future soil movement and sinking.

Mudjacking is suitable for sidewalks, driveways, patios, and nearly all exterior flat structures. However, it may not suit severely damaged or heavily cracked areas.

A sinking foundation can be lifted, most often by installing piers to re-level and support the weight of the house. Depending on the cause and extent of the sinking, other methods to lift a foundation include underpinning and mudjacking. Consult a foundation repair pro to determine the best way to lift your sinking foundation. 

Yes, expanding foam (also known as polyurethane foam) can lift concrete. This approach, called polyjacking, involves injecting the foam rather than concrete slurry to fill voids and raise the concrete slab back into place. It’s often faster and requires smaller drill holes than traditional mudjacking, though it may come at a higher cost. Some contractors also prefer polyjacking over mudjacking for more damaged and delicate slabs.
