Why should I use slabjacking? Raise concrete at ¼ the cost of replacement Stabilize the sub-soil Strengthens the slab Eliminates erosion Done in less time than replacement

Slabjacking is defined as "grout pumped under pressure through injection holes (usually 1.5 inch diameter) to raise faulty or sunken concrete". Other spellings are slabjack or slab jack. The process begins by drilling holes, then void filling the entire sub-grade, raising the concrete to it’s original elevation. Using a Black-Jack Grout Pump, our exclusive non-shrink cement grout is pumped under the sunken concrete at the rate of 1 cubic foot per minute. After the lifting is complete, the area is cleaned of excess drill tailings and grout, then the holes are re-cemented with our custom color matching system. Most work can be completed in less than 4 hours.

Although Slabjacking or Concrete Lifting are the preferred terms for concrete repair or to raise concrete, mudjacking and mudpumping, are terms commonly used in our industry. Poor long-term results occur when mud or topsoil are mixed with sand and water and injected under the sidewalk, driveway, or any concrete pavement. Test studies prove this organic, mud blend breaks down in less than 1 year causing re-sinking of the concrete pavement.

Black-Jack Grout Pumps Inc. continues to developed and test the most advanced, easy to use pumps on the market today. Our Black-Jack grout pumps are used for any type of pressure grouting. Although grouting is the primary use, the Black-Jack can be used as an epoxy pump specializing in polyurethane injection.
