Concrete Lifting

Bay Area Underpinning offers the exclusive PolyRenewal™ system, a proven solution for lifting and securing sunken concrete slabs.

Schedule Free Inspection

Despite being a widely used fundamental construction material, concrete is still prone to damage. Whether it’s pool decks, patios, sidewalks, or driveways, the concrete on your property can develop cracks and settle over time. 

These issues pose significant dangers to your home and loved ones. Cracked or sunken slabs diminish curb appeal and create safety hazards for those walking or driving on your property. 

Preserving the integrity of concrete slabs is vital for safety, aesthetics, and property value. It’s vital to tackle these problems promptly by consulting local concrete lifting specialists for a thorough inspection and professional repair solutions. 

As the leading authority in the industry, Bay Area Underpinning has been helping homeowners in the Bay Area lift and stabilize their concrete for nearly 20 years. Our team of experts uses the SettleStop™ PolyRenewal™ concrete lifting system to swiftly identify and repair problematic concrete. Let’s work together to restore your concrete to its former glory. 

Concrete Problem Signs

Identifying signs of undermined concrete caused by unstable soil, oversaturation, poor drainage, invasive tree roots, or installation issues is crucial. Early detection allows us to customize repairs for your property’s specific needs.

Had BAU take care of a chimney that was leaning away from my home, fix my front door which would jam at times of the year and relevel my floors. This was my second time working with BAU who installed screw jacks and leveled my floors several years ago. This time, Juan took a look at the problem areas, took measurements, made recommendations that fit my needs and budget and answered all my questions. Gonzalo and team came to work on my property. They worked quickly to install piers under the chimney and in the crawl space. They put tarp down to keep the house clean in the areas they needed access and cleaned up after themselves each day on the job. They answered my questions and throughly explained the problems and solutions they would implement to level the floor. Overall, I'm pleased with their work, being on time each day, and communication skills and would recommend.

The permiting process took a long time, but that's not their fault. The cost was very high but competitive with another contractor.

I had a great experience with Bay Area Underpinning. They fixed my foundation, which was a substantial job, in a matter days, and did all of the engineering and permitting at a very fair price. I cannot say enough good things about Tyler, Angelo, and Louise, who did all the hard work. They were on time each day, very diligent, and patiently answered all of my questions. Then, when the job was finished, they cleaned the work area and left it in a better condition than they found it. That was awesome, and tells you what you need to know about these guys and the company. I couldn't be happier.

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.

I hired BAU to underpin our foundation. After extensive research I learned that BAU does the best work and at reasonable prices. Jordan lead the crew that did the work on our house, and he was a joy to work with and we really trusted him and his team to take care of us. I am really glad we hired BAU, and we are happy to have our hillside home properly secured for the future!

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!

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.

We had an amazing service experience from David and Rico of Bay Area Underpinning. David and Rico were very professional, super nice, and worked hard on leveling my floor. They arrived on time after giving me a call earlier to let me know they are on the way. They put on shoe covers to make sure my floor is protected. They patiently listened to my inputs and addressed my concerns with competence and great care. And they would not leave until all the uneven floor areas are fixed to my satisfaction. This team deserves my 5 star rating.

I had Joe inspect the crawlspace of my home, and I couldn't be more satisfied with the experience. First off, he did the inspection for free, which is rare these days! Joe was professional, punctual, and thorough in his inspection, explaining everything he found in a way that was easy to understand. He took the time to ensure I knew what was going on beneath my home and didn't push any unnecessary services. I highly recommend him for anyone in need of an honest and detailed inspection. Definitely a 5-star experience!"

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.

We just bought a house, and literally every single metal pier in the crawlspace was rusted out. Bay Are Underpinning came in and did an awesome job. Their inspector Aaron was super thorough in assessing the damage and explained everything in detail. Then, the repair crew of Eric, Jesus, and Andrew came in and knocked out the entire job in a day — a huge relief considering we had a ton of other work we need to get done before moving in. The work is not cheap, but they offer financing options and stand by their work, so I feel very good about the entire job.

What is PolyRenewal™? 

PolyRenewal™ is a cutting-edge solution for sunken and cracked concrete. Our lightweight polyurethane foam gently lifts and stabilizes concrete slabs. 

Bay Area Underpinning uses this system by injecting high-density, closed-cell polyurethane foam beneath affected slabs, effectively stabilizing the concrete and underlying soil. This approach is superior to traditional methods like mudjacking, offering longer-lasting results with minimal disruption. 


Concrete Lifting Solutions

Bay Area Underpinning’s adaptable PolyRenewal™ system suits various concrete surfaces on your property, ensuring an ideal solution for all your concrete repair requirements. 

FAQs

Concrete may sink due to various reasons, including settling or eroding soil, oversaturation from precipitation, expansive soil, drought conditions, poor drainage, invasive tree roots, ground movement, and installation problems. Promptly addressing these issues is vital to prevent future structural damage. Our experts will identify the causes and recommend suitable repairs during a free inspection

The cost of our services varies based on factors like damage extent, treatment area size, and site conditions. During a free inspection, we provide a tailored, accurate estimate. We also offer transparent pricing, no-obligation repair estimates, and various financing options

Bay Area Underpinning specializes in the PolyRenewal™ system because of its superior, quick-curing, and long-lasting results. We do not offer methods like mudjacking, repouring, or patching, as they are less effective, more invasive, costly, and fail to address the root issues. Choose a durable repair that safeguards your home for years to come. Learn more during a free inspection with one of our experts.

Disclaimer: “Concrete leveling” means the process by which cracked, uneven concrete is stabilized, and in many cases lifted, by means of PolyRenewal™ polyurethane foam. Bay Area Underpinning does not guarantee that PolyRenewal™ can make your concrete perfectly level.
