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.

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 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.
