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
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.
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. DOTs interested in specifying Prime Resins products, go here.
There are many benefits of using chemical grouts vs substrate replacement or excavation repair:
