Concrete Raising – Mudjacking


Mudjacking, has been the default method of concrete raising for decades. It’s quick, simple, and shows immediate results. This method is best for large-area concrete slabs with a relatively heavy load. Also check out our state-of-the-art polyurethane slabjacking method for almost any application!

Concrete Raising is simple, less intrusive, and much less expensive than concrete removal and replacement.

How Mudjacking Works

Small holes, generally 1 ⅞ inch or less are drilled into the concrete slab that needs raising. A concrete slurry is pumped into these holes under slight pressure in order to fill the voids under the slab. As pressure builds, the slab is hydraulically raised to the necessary grade, removing the trip hazards and unevenness of the concrete.

The final step is to fill the small holes with a concrete mixture, restoring the integrity to the cracked driveway, sidewalk, or concrete slab that is being raised.

Mudjacking isn’t complicated, but it’s not DIY.

Experienced professionals should perform this procedure to avoid doing even greater damage to your concrete slab. Amateur work often results in further, or irreparable damage that usually costs more to repair or replace than the original damage.

2. A sand and cement mixture is then pumped under pressure through the holes filling any voids and raising the section of concrete to its original elevation.
