How We Raise Concrete
Whether it’s due to poorly compacted fill soils or tree roots, concrete can settle over time, resulting in a variety of problems. American Concrete Raising offers solutions to these problems using mud-jacking (also known as slabjacking) technology. In addition to leveling the concrete, these cost-effective options can increase the value of your property, eliminate safety hazards, and reduce embarrassment of an unsightly nuisance. We can raise concrete on any flatwork, including:
- Garage floors
- Concrete pool decks
Mudjacking is the most common technology that we use at American Concrete Raising. This technology involves using hydraulic pressure to raise settled, uneven concrete by pumping a grout-like mixture of clay, fine aggregate, and Portland cement below the slab. The process is safe, simple, and cost-effective and involves the following steps:
- Small diameter access holes (about 2”) are drilled into the concrete surface.
- The mixture is injected into the holes to fill any voids.
- Once all spaces are filled, more of the mixture is injected in the holes to lift the concrete. The concrete is filled until it’s leveled, which takes minutes.
- After the concrete slabs are raised, the access holes are patched with concrete and finished to match the surface of the surrounding concrete, and the job is complete.
Thanks to the physics of hydraulics, we have plenty of raising power with just a small amount of pumping pressure. The uplift motion is slow, usually about ¼ of an inch per minute.
