Sunken Concrete is Both a Safety Hazard and a Liability


They aren’t just eyesores. Sunken, uneven concrete sidewalks, driveways, and pool decks are also trip hazards. That’s a serious liability that could result in injuries and even lawsuits. Therefore, this is not a repair you want to put off.

We are able to lift sunken or settled concrete slabs in Fairfield, CA including, but not limited to…

Benefits Of Concrete Lifting Via Polyurethane Foam Injection

The benefits of concrete lifting – also known as slabjacking or polyurethane foam injection – are many, including:

  • It’s permanent. Other methods of lifting concrete – mudjacking, for example – add even more weight to soil that’s already having trouble supporting a slab. Because polyurethane foam is lightweight, it doesn’t add more weight to the soil which means the slab won’t continue to sink. It will remain even.
  • It’s cost-effective. Concrete lifting via polyurethane foam injection costs less than replacing a concrete slab.
  • It’s quick. With polyurethane foam injection there’s no downtime where you can’t use the slab. As soon as the repair is complete, you’re good to go!
  • It’s lightweight. Polyurethane foam is super lightweight and doesn’t add extra weight to the soil. Other methods of lifting concrete such as mudjacking do add extra weight to the soil. If the soil was already having trouble supporting the slab, adding more weight to it via mudjacking won’t help.
  • It won’t harm the environment. Polyurethane foam doesn’t release harmful chemicals into the soil. Therefore, you can feel comfortable knowing it’s a safe, green solution.
  • Even concrete just looks good Sunken, uneven concrete is an eyesore!

What Causes Concrete Slabs To Sink Or Become Uneven?

Concrete slabs sink and become uneven for a variety of reasons including…

Problems with drainage. When there’s too much water under a slab it can wash away the soil and leave behind voids that the sidewalk, driveway, or pool deck will sink into.

Weak soil that isn’t able to properly support a slab. Some types of soil simply aren’t strong enough to support the weight of a concrete slab.

Expansive soil. This is soil that expands when it soaks up water and then shrinks when it dries out. Over time, this movement in the soil can lead to uneven slabs.

Invasive tree roots. This works exactly as you probably imagine. The tree’s roots push against the slab and cause sections of it to become uneven.

What are the Different Ways to Lift a Concrete Slab?

There were two traditional methods of lifting a concrete slab, mudjacking, and digging up the old slab and replacing it with a new one. Each method has its own drawbacks though, and as you’ll see, polyurethane foam is the best solution for lifting a concrete slab.

Mudjacking

Mudjacking is a procedure that injects a cement slurry under a slab in order to raise it up to where it was before. Yes, it works, at least temporarily. The problem with mudjacking is the fact that cement slurry is heavy. If you put it on top of soil that was already having trouble supporting a slab, this isn’t going to help in the long run. In fact, it could even make the problem worse.

Concrete Replacement

Tearing up an uneven concrete slab in order to pour new concrete is an expensive and time-consuming repair. Freshly poured concrete needs time to cure and harden. That means you won’t be able to use the slab right away after the repair is complete. Also, if the soil was having trouble holding up the slab before, replacing old concrete with new concrete isn’t going to solve the problem.

Of course, you should never pour new concrete onto an uneven slab in order to even it out. That will only add more weight to it, which is not what you want.

Polyurethane Foam Injection

Polyurethane foam injection (commonly referred to as ‘’slabjacking’’) involves injecting a lightweight and rapidly expanding foam under a concrete slab in order to raise it back to where it was. It’s a fast, minimally-invasive repair, and unlike replacing the concrete, there’s no downtime. After the repair is complete you can immediately start using the slab again.

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 called in Bay Area Underpinning for foundation work. They were wonderful answering my many concerns, I received prompt return calls, the work was completed within an appropriate time frame, and the best thing he stayed with the estimate to the dollar. I loved the engineer, time frame, and minimal damage repair. I didn't know how my house was going to respond and even the marble and windows handled well. Unfortunately I didn't get the exact lift I wanted in the office even though they tried their hardest. My advice — call them when the problem first arises and the outcome and the house will lift with ease. I definitely recommend BAU. Because I live on a hill one pillar had to be covered – done. I also had a French drain installed to divert the water which was recommended. Thank you

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.
