The Foam Jack is a high pressure portable foam jacking machine that can use high pressure spray polyurethane chemicals. This spray technology is everything you need to get your concrete lifting and maintenance jobs done quickly, safely and affordably.
Slab settlement can affect new and old structures alike. Whether you are dealing with a sinking slab in your basement, garage, driveway or patio, a cracked sunken slab creates an uneven surface that can pose a safety hazard.
The Gusmer GX-7 plural component spray gun is recommended for spraying foam only and is a mechanically self-cleaning spray gun which eliminates costly solvent flushing. The Graco GX-7 spray gun is one of the industries choice guns when it comes to applying two-component foam systems. Excellent for spraying polyurethane foam the Graco/Gusmer GX-7 foam gun is world renowned and proven itself with many foam companies over the years.
When you are dealing with cracked and settling concrete, there are typically two ways to fix the problem: replace the slab with new concrete or raise the slab by pumping a mortar-based mixture underneath the settling slab in a process known as mudjacking.
Mudjacking, slabjacking, and slab raising are all terms to describe the same process. Mudjacking, a concrete lifting technique, has long been an effective alternative to replacing sunken or uneven concrete slabs. Raising settled concrete is much less expensive than concrete replacement.
The problem with traditional mudjacking is that the weight of the “slurry” mixture that is pumped under the slab, combined with the weight of the concrete itself, can actually cause the slab to sink further if the soil beneath isn’t able to support the load.
