Mudjacking

Mudjacking is the most effective way to save concrete slabs by raising them back to the proper level and grade. It is the typical service we offer to repair concrete settlement issues.

We literally use “mud”—a slurry of water and non-shrink grout—to “jack” up the sunken concrete slab. First, we drill a set pattern of holes into the sunken concrete slab. Then, we use a Mudjacker to pump the non-shrink grout through the holes. The non-shrink grout fills voids, raises the concrete slab and stabilizes it.

While there are many different varieties of non-shrink grout, not all grouts are appropriate for all situations. Based on our 35 years of experience and training, Concrete Pressure Lifting, Inc. selects the best-suited grout for each specific assignment. Our preferred all-purpose grout is agricultural lime, because it maintains flexibility over time and it is environmentally friendly. Agricultural lime is superior to “cheaper” alternatives, such as calcium carbonate and swamp silt.

Why did my concrete sink?
Over time, the weight of the concrete pushes down on the soil underneath, causing the ground to “compact,” or become more dense. As the soil compacts, the concrete resting on top of it will sink. Because of varying soil conditions and drainage patterns, the areas under the concrete slabs will compact to different densities, which creates uneven concrete.

Before Mudjacking

Before Mudjacking

Before mudjacking, the sidewalk has pulled away from the building, creating an uneven surface. In this “before” image, there is a significant gap between the building and the concrete sidewalk. Over time, this gap will lead to increased erosion, as well as potential water damage to the foundation of the house. The sidewalk beside the building is also uneven, which creates a tripping hazard.

After

After Mudjacking

After mudjacking, the sidewalk is even and flush with the building. Sealant is applied between the building and sidewalk. As part of the process, we applied sealant to help prevent future erosion and water damage. The entire process was completed in a matter of hours, with minimal mess and disruption. Best of all, the newly-repaired surface can be used immediately!
