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.

Bay Area Underpinning is OUTSTANDING!! Cody, Andrew, Francisco, David and their underpinning and concrete teams did exceptional work installing underpinnings to stabilize our house, then replacing the concrete patio that had to be removed to do the stabilization. Everyone on the teams were efficient, courteous, highly skilled, and thorough. I cannot recommend Bay Area Underpinning highly enough- through each step of the process, from the initial assessment and work quote, to the work and follow-up itself, the staff and crews of Bay Area Underpinning ensured that I was informed, reassured, and we’ll take care of. They were thoughtful about doing their work efficiently and cleaning up after the work was completed. I cannot recommend them highly enough!

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.
