We are providing links to videos of mudjacking from other cities to give our customers a demonstration and idea of how the process works:

Mudjacking is the process of pumping a water, crushed limestone and portland mixture under a concrete slab in order to lift it. This mixture is called slurry. The exact ingredients vary from company to company, and from job to job. Mudjackers & Concrete Repair uses ground limestone, portland cement and water; some companies use soil instead of limestone. Mudjacking can be the solution to many homeowners’ concrete problems, including raising fallen driveways, sidewalks, steps, patios, and pool decks. Industrial and commercial applications include  raising warehouse floors, curbs and parking lots.

Concrete can sink or settle for several reasons. If the original concrete was installed on dirt that had not been compacted properly, the slab will start to settle within a few years. Soil erosion is another big contributor and is fairly common in some parts of the United States. The earth also naturally settles over time so if the slab is over seven to ten years old, it may be the natural progression of things. In any case, once the concrete does start to tilt or sink it can cause safety and walking hazards, unwanted water runoff, or major foundation issues.

The entire process is fairly simple. First, small holes are drilled into the concrete slab to be lifted. Slurry is then pumped into these holes under pressure, filling any gaps under the slab. When the gaps are filled, the slurry becomes pressurized, and raises the slab hydraulically to the necessary height. In the final step, the holes that were originally drilled are then filled with a concrete mixture.

Mudjacking is not a complicated process, but it’s a process that requires extensive knowledge and training to get the desired results. Occasionally mudjacking won't achieve desired results and concrete will need to be replaced.

Normally mudjacking is a more efficient alternative to replacing concrete. Ripping out old concrete, and laying new concrete, requires more equipment, and more workers, than mudjacking does. This makes the replacement costs nearly three times more than mudjacking. Not only is mudjacking less expensive it's quicker and cleaner, and it also sets more rapidly. Certain concrete pours may take days to cure fully, while concrete that’s been mudjacked can be ready within hours. There is also little need to disturb adjacent landscaping or plants, making the whole endeavor a much neater and desired process.

Once the mudjacking is complete both the concrete slab and the soil beneath it will be much more structurally sound. The fact that mudjacking is using the same concrete slab is another benefit. Aged concrete is structurally superior to new concrete. As long as settling is the only issue, repairing the old slab may be better than pouring a new one.  Mudjacking is certainly faster, cleaner, easier, and less expensive.
