Sunken Concrete is Both a Safety Hazard and a Liability

Because an uneven concrete slab is a trip hazard, this is a repair you don’t want to postpone. If someone trips and gets injured you could find yourself facing a lawsuit.

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 a repair that lasts. The foam used to lift a sunken concrete slab is light as a feather and won’t add additional weight to soil that is already struggling to hold up a heavy slab.
  • It’s cost-effective. It’s less expensive to lift a slab using polyurethane foam injection than it is to dig up and replace the slab.
  • Most jobs can be completed in just a few hours. After the slab has been fixed, you can immediately start using it. No down time.
  • It won’t leach chemicals into the soil.  This makes polyurethane foam a green solution.
  • Uneven 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 various reasons including…

Too much water in the soil. Water can cause soil erosion and leave behind voids. The slab sinks into the voids and becomes uneven.

The soil under the slab is weak. Some types of soil aren’t strong enough to support a heavy slab.

Expansive soil. Expansive soil expands as it absorbs water and contracts as it dries out. Over time this swelling-shrinking cycle can result in an uneven slab.

Invasive tree roots. This happens when large roots push against a slab and cause sections of it to become uneven.

What are the Different Ways to Lift a Concrete Slab?

Today, there are two ways to lift a sunken concrete slab: Polyurethane foam injection and mudjacking. Mudjacking is the “old school” way of fixing a sunken slab and isn’t as common as it once was. Most contractors today use polyurethane foam injection to lift sunken slabs. Of course, another way of repairing a sunken slab is to dig it up and replace it. However, this is expensive and time consuming.

Mudjacking

Mudjacking used to be the go-to method for fixing sunken slabs. The main problem with mudjacking is the weight of the cement slurry used to lift the slab. It weighs a lot, and if the slab became uneven because weak soil wasn’t able to support it, mudjacking could make the problem worse.

Concrete Replacement

Replacing a slab means digging up the old one and pouring new concrete. This solution is both expensive and time consuming. You can’t use a freshly poured concrete slab right away because it needs time to harden. Also, if the slab became uneven because of weak soil, the same thing will happen to the new slab.

Polyurethane Foam Injection

Polyurethane foam injection (also known as ‘’slabjacking’’) is a fast, minimally-invasive technique for lifting sunken concrete slabs. Most repairs can be completed in a few hours and then the slab is ready for use. It’s also less expensive than tearing up and replacing the slab.

Would highly recommend!

Bay Area Underpinning is THE company to use for foundation work. Aaron, and his crew, were incredibly professional from start to finish. The team kept the work space clean and tidy, communicated well, and updated me as timelines were solidified. They were always on time and ready to maximize their output for the day. I would recommend them in a heartbeat.

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

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.
