Seal leaks in concrete or masonry with crack injection and curtain grouting of our Prime Flex polyurethanes and AR acrylate resins. Prime Resins offers superior solutions for stopping leaks in every type of environment.
Sound concrete relies on a sound substrate. Stabilize soils and fill voids with our polyurethane and acrylate foams and gels. We make chemical grouts for permeation and compaction grouting in wet and dry conditions.
Slab lifting and slab stabilization with polyurethane foams offers many advantages over traditional mudjacking. Only Precision Lift is engineered to tackle underlying issues and slab lifting with precise, dependable results.
Protecting concrete usually means shielding it from the elements of nature or from harsh manmade chemicals. But it’s not just concrete that needs such protection. Corrugated metal pipe, steel surfaces, material hoppers, rail cars and masonry all can come in contact with corrosive or abrasive materials or harsh conditions.
Spalled concrete is concrete that is chipped, cracked and deteriorating. This often happens at a joint.
You can repair a seawall or bulkhead with Prime Resins chemical grouts: fill voids, stabilize loose soil and seal leaks at a fraction of the cost of wall replacement.
The need for crack repair in concrete structures can be caused by many different factors. Damage can occur to the concrete in situations where direct impact puts stress on one area of the structure.
The geotechnical needs of DOTs and other agencies responsible for roads and bridges are vast. Issues include: Culvert repair Soil stabilization Void filling Concrete slab lifting Sinkhole remediation Slope control Slough control in tunneling

Asphalt highway stabilization with polyurethane provides a long-term solution to an ongoing settlement problem, keeps a busy interstate highway open during repairs.
Contractor: Applied Polymerics
Client: North Carolina DOT
A section of I-40 in the Winston-Salem, N.C. area had settlement issues. A stretch of the asphalt highway leading up to a bridge approach slab repeatedly experienced settlement, causing a dip in the road. The DOT kept having to repave that section only to have it sink again. It is likely that old organic fill underneath the highway decomposed over the years leaving voids and loose soil.
As a result, the DOT decided to solve the settlement issue once and for all and then complete a full repaving project. The DOT wanted to ensure it wouldn’t have to keep repaving that one section repeatedly.
The DOT contracted Applied Polymerics to stabilize the soil beneath the stretch of highway using polyurethane resin so that it would stop settling. The reconstruction alternative was not really a viable option since that would require closing the busy interstate highway. The Applied Polymerics crew drilled a grid pattern and injected the soils underneath with Prime Flex 910, a single-component, moisture-activated polyurethane resin.
“We did permeation grouting below the asphalt roadway,” said project lead Scott Kammerer. “We chose that product as the best option because no lifting was required, just stabilization. After injection, the DOT would not have to worry about further settlement.”
Prime Flex 910 is a super low viscosity resin, allowing for thorough penetration of the voids and loose soil under the highway. The resin reacts with moisture present in the soil and cures quickly to form a hard, water insensitive mass. The consolidated soil provides proper support for the structure above.
“Everything went well,” said Kammerer. “This was a pretty standard soil stabilization job. The project ultimately required approximately 900 gallons of material. That section of highway remains stable, without settlement, years later.“
