The Polyseal Raising Process

The Polyseal Process is similar to mudjacking, but is an evolved application that allows us to provide our clients with a clean, quick, long-lasting solution. Our process effectively stabilizes soils, fills voids and lifts concrete using high-density polyurethane foam. The following are the steps for The Polyseal Process.

The Polyseal Advantage

Smaller Holes

With polyurethane foam, we are able to use smaller drill holes than what is required with traditional slabjacking methods. Polyseal uses small, 5/8" (dime-size) drill holes to complete our concrete raising projects.


Polyurethane foam is a light weight material compared to traditional mudjacking slurry (2-6 pounds of polyurethane foam vs. 100-130 pounds of mud slurry). Because of the light weight properties of our foam, it won't burden the underlying soils which are often loose and poorly compacted. Mud slurry is extremely heavy and within a couple years can compact the loose soil base causing resettlement.

Fewer Holes

With foam, fewer holes are drilled in your concrete for a cleaner look compared to mudjacking. Because polyurethane foam enters the soil base as a highly pressurized liquid, we can achieve a large coverage area from each injection site. Our polymers can flow and expand anywhere from 4 to 15 feet from each injection site. Because of the heavy nature of mud slurry only 1-2 feet of coverage should be expected from each drill hole. As a result 50%-75% more holes are needed to repair sunken concrete with mudjacking.

Long Term

Lifting settled concrete with polyurethane foam is considered a long-term repair, not a temporary fix. Our lightweight high-density foams won't loose density like mudjacking slurry. Our hydrophobic foams cure in 25 – 45 minutes and will completely maintain their compressive strength. Also, our foams won’t break down or washout from water, making The Polyseal Process a long-term solution.
