Chemical Grout Injection

Chemical Grout Injection Chemical grouts represent a large family of predominately urethane-based grouts. Leaks and infiltration can be controlled in structures such as tanks, vaults, tunnels, concrete dams and below grade pits with this process. In this process, material is placed under pressure, using either single or plural component pumps, then injected through a series …

Fiber Reinforced Polymers

Fiber Reinforced Polymers Fiber-reinforced polymers (FRP) (also fiber-reinforced plastics) is a composite material made of a polymer matrix reinforced with fibers. Externally or internally installed, FRP is engineered to increase the load capacity, strength and potentially provide protection from external environmental attack. FRP is also an effective way of regaining structural integrity in structures where …

Epoxy Pressure Injection

Epoxy Pressure Injection Epoxy pressure injection is the process of injecting epoxy-based construction adhesives to bond concrete, and in some instances, laminated wood structural beams. In addition, epoxy pressure injection is often used to bond delaminations and fill voids under equipment base plates, providing 100 percent bearing capacity. This process also protects the rebar and …
