Concrete Leveling

What is concrete leveling?

Concrete leveling (also known as slabjacking or mudjacking) is a method of correcting an uneven concrete surface by altering the foundation that the surface sits upon. It is a cheaper alternative to having replacement concrete poured, and is commonly performed at small businesses and private homes as well as on roads and highways. Driveways, concrete patios, sidewalks, pool decks, bike paths, and concrete interior floors are all good example of its uses.

Why is concrete leveling needed?

There are a variety of reasons that concrete sinks or settles. Some of the most common reasons include concrete that was installed on improperly compacted soil, soil erosion due to environmental factors, and water penetration through the concrete joints. Regardless of the cause, sinking or tilting concrete can lead to severe slab issues, improper water runoff, and even trip hazards.

How does concrete leveling work?

A number of small holes are drilled in the sunken concrete. By pumping a slurry (a specialized mixture of water, dirt and cement) into the desired area, the cavities underneath the slabs are filled and stabilized. Increasing the pumping pressure allows driveways, sidewalks and floor slabs to be raised in a controlled manner. The work is accomplished by utilizing specialized pump equipment that delivers the slurry at a slow, continuous rate which allows for precise leveling. Once the slab has been raised and leveled, the drill holes are patched and the surface is ready to use.
