Concrete Lifting in Concord, CA
If you have a sunken sidewalk, driveway, pool deck, garage floor in Concord, CA, we can lift your concrete.
Sunken Concrete is Both a Safety Hazard and a Liability
Sunken, uneven concrete sidewalks, driveways, and pool decks are more than just eyesores. They’re trip hazards, and a liability that could result in injuries and even lawsuits. Therefore, it’s not a repair you want to put on the back burner.
We are able to perform concrete lifting on sunken or settled concrete slabs in Concord, 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 numerous:
- It’s permanent. Because polyurethane foam is lightweight it won’t add more weight to the soil. Other methods of lifting sunken concrete – such as mudjacking – might lift the concrete temporarily. However, the weight of the cement slurry used to lift the slab adds even more weight to the soil. If the soil was already having trouble supporting the concrete, eventually the slab will start to sink again.
- It’s cost-effective. Concrete lifting via polyurethane foam injection is less expensive that replacing the concrete.
- It’s quick. You can use the slab immediately after the repair is complete.
- It’s lightweight. Polyurethane foam is able to lift the concrete without adding extra weight to the soil. This is important because if you use a technique that adds extra weight to the soil – like mudjacking – the slab could continue to sink simply because the soil isn’t able to support it.
- It’s not harmful to the environment. Polyurethane foam doesn’t release harmful chemicals into the soil. Therefore, it’s a 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 for a variety of reasons including…
Problems with drainage. Excess water can wash away the soil under a slab and leave behind voids that the sidewalk, driveway, or pool deck will then sink into.
Weak soil that can’t hold up the slab. Sometimes the soil under the slab simply isn’t strong enough to support the weight.
Expansive soil. This is soil that swells when it soaks up water and shrinks when it dries out. Over time this movement in the soil can cause uneven slabs.
Invasive tree roots. You can probably imagine how this works. The roots push against the slab and cause sections of it to become uneven.
What are the Different Ways to Lift a Concrete Slab?
Traditionally, uneven concrete slabs were repaired either via a technique called “mudjacking”, or by tearing up the uneven slab and pouring new concrete. Both methods have significant problems though. We’ll explain both methods and then explain how polyurethane foam injection works and why it’s the best way to lift and level a concrete slab.
Mudjacking
Mudjacking involves injecting a cement slurry under the slab in order to lift it back up again. The problem with this method is the fact that the cement slurry is heavy. It’s cement, after all. If the soil was already having trouble supporting the slab, adding more weight to it is only going to cause it to sink even deeper into the soil.
Concrete Repair
Replacing an unlevel concrete slab means tearing up the old one and then pouring new concrete. This is an expensive and time consuming fix. Newly poured concrete takes time to harden and cure. That means a certain amount of downtime until the new slab can be used. Also, if the slab sunk because the soil couldn’t support it, the new slab will suffer the same fate.
Of course, it goes without saying that you should never be tempted to add concrete on top of a slab in order to even it out. This will only add more weight to the slab and cause it to sink at an even faster rate.
Polyurethane Foam Injection
Polyurethane foam injection (also known as ‘’slabjacking’’) is a minimally-invasive, cost-effective procedure that involves injecting a special, lightweight and rapidly expanding foam under the slab in order to lift it back up again. It’s a fast repair, and after it’s complete you can immediately start using the slab again.

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.
