Slabjacking-Mudjacking-Concrete Lifting

Slab jacking – also referred to as mud jacking or concrete lifting, is a process of lifting concrete slabs that have settled. This is accomplished by drilling holes through the slab and pumping a sand/cement mixture under the slab(s). Slab jacking provides a liquid shim under the slab, which allows the slab to be guided to its original location.

Sinking or sunken concrete driveways, walkways, patios, pool decks, stair stoops factory floors and even roadways can be raised to their original elevation by slab jacking services. Slab jacking is a legitimate alternative to costly concrete replacement. By lifting the concrete instead of replacing it you will save money, labor & dumping fees, plus your slab(s) can be used the same or next day. Slab jacking does not affect your landscape either. Save up to 70% of the cost of replacement by raising the concrete by using slab jacking services.

Slabjacking, also known as mudjacking, is a way to raise sunken concrete. People have used the technique since the 1930’s, but the process is more familiar in the Midwest and on the East Coast, where seasonal temperature extremes cause concrete to buckle and sink. In the central Texas area our situation is a little different. Here, builders are using expansive clay to back fill around new home construction and then pour the patios, sidewalks and driveways on the freshly groomed base. The problem is that the soil is actually compressive for the first few years and will often settle several inches over the first 5-7 years. Sometimes runoff directly from the roof or improperly placed downspouts cause flooding and even subterranean animals can create voids under the concrete that cause it to settle. This settlement causes concrete to tilt or sink creating trip hazards and causing water to pool or flow towards the house. Slab jacking removes these hazards and it’s a less expensive alternative to removing damaged concrete and re-pouring it. Re-pouring concrete creates it’s own problems as it most likely will not match your existing concrete.

Here’s how Slab jacking works: Holes are drilled through concrete slabs every four feet. A hydraulic pump pushes slurry through a hose inserted in the hole and under the slab. The slurry slowly raises the slab and fills the voids underneath. The slurry used is a mix if crushed limestone, Portland cement and Bentonite. We patch the holes we have made after the lift is complete

The prices of jobs vary depending on a number of factors. Prices vary due to the size and thickness of your slab and how deeply it has settled plus the ease of access to the work site. On average, you can plan on saving 50% of the cost of replacement by slab jacking. We would be happy to provide a free estimate for your project.

Most slab jacking projects take approximately a day or less. Homeowners can walk on the lifted concrete within 30 minutes, although we do not recommend parking on top of slabjacked concrete for two to four days to allow the material below the slab to cure.
