What is SlabJacking?

Slabjacking is defined as “grout pumped under pressure through injection holes (usually 1.5 inch diameter) to raise faulty or sunken concrete”. Slabjacking is also referred to as slabjack, slab jack, mudjacking, and pressure grouting within the industry.

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.

Before Black-Jack: Sidewalk is uneven & dangerous.
After Black-Jack: The sidewalk is smooth & even.

Before Black-Jack: The sidewalk has collapsed.
After Black-Jack: The sidewalk is level and safe.

Why Should I Use Slabjacking with Black-Jack Grout Pumps?

Better, safer, more cost-effective, with long-lasting results.

  • Raise concrete at ¼ the cost of replacement
  • Stabilize the sub-soil
  • Strengthens the slab
  • Eliminates erosion
  • Done in less time than replacement

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 develop 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.

Quality Product at a Fair Price

I am pleased with my overall experience with Black-Jack Grout Pumps. When I first went into this business, I was concerned about the initial investment. Then I discovered Black-Jack.

I was surprised to find what turned out to be a quality product at a fair price. They were helpful and patient with me as I wrestled with the decision to purchase. After I did place an order, they continued to be supportive. Now that I have the equipment and am operating a successful business, I continue to enjoy their support and their willingness to stand behind their product.

Black-Jack provided us with the knowledge and equipment to be successful.

Thank you for taking the time to provide us that great training. I am starting my own mudjacking business from scratch with limited knowledge. Your class helped me from the first steps to the final steps of the mudjacking process. I appreciated the knowledge you shared with me in regards to marketing my business. You provided us with all we would need to be successful in the field. You started with tools of the trade, went through the internal components of my pump, what parts to have on hand for repairs in the field if needed, how to mix the concrete and what to look for in the cement, ad mixtures, where to drill the holes, and how to finish the job. It was a great all-around training session that enables me to go out and be successful in the field.
