CONCRETE LIFTING
CONCRETE LEVELING
SLABJACKING
MUDJACKING
WHAT’S THE DIFFERENCE?
Concrete Lifting is a repair method for raising concrete back to its maximum practical level. This is accomplished by drilling holes through the concrete slab and injecting a filler material underneath it. The filler material takes up space under the slab and raises it- or jacks it- to the desired height. Both mudjacking and slabjacking are methods of concrete lifting and concrete leveling.
Concrete Leveling is essentially the same process as concrete lifting. The two are often used interchangeably, although concrete leveling is a misleading term. When a contractor says they’re going to “level” your concrete slab, this may not be 100% accurate. This is because outside slabs aren’t level- and you don’t want them to be. When concrete is poured outside- whether it’s a driveway, a patio, a walkway- it’s meant to include a gradual slope away from your home. This is how water drainage is managed on an outside concrete slab.
Mudjacking is a type of concrete lifting. Holes are drilled through the concrete slab and filler is injected that is referred to as “mud” or a concrete slurry. It’s a proprietary mixture of concrete, sand, limestone, water, and other materials that vary, depending on the equipment and the contractor that is doing the work. The pressure of forcing this material under the slab is what lifts the slab. Mudjacking is an older method of concrete lifting.
Slabjacking is another type of concrete lifting- but it does not involve a concrete or limestone slurry as a filler. At Level Best Northwest, we use a two-part polyurethane foam as the filler material.
The injection foam is easier to control, faster to set up, and lasts significantly longer than “mud or slurry.”
Level Best Northwest utilizes the Slabjacking method because polyurethane foam does not decompose; unless the ground below the foam erodes, the foam will keep the slab in place indefinitely.
