Fundamental to healthy concrete is a solid substrate. Well-compacted soils provide a foundation upon which concrete structures perform. Over time, forces of nature take their toll. Decomposing soils, erosion, freeze-thaw cycles and groundwater migration can break down this foundation. This is the root cause for the damage or failure of many structures, from buildings to highways.


Injecting polyurethane resins and gels into loose or less dense soils, voids, pores and fissures will strengthen the earthen substrate and provide watertight encapsulation. Prime Resins has been providing soil stabilization solutions for nearly 30 years with our Prime Flex polyurethane foams and gels. The techniques and products used depend on what you are trying to accomplish, the type of substrate you are working with, and what type of equipment you have available. DOTs are responsible for many structures requiring stabilization and void filling. Our products meet or exceed existing specifications for soil stabilization, void filling and slab stabilization.
