It is common for concrete to develop cracks. Cracks can be due to drying shrinkage, expansion and contraction from temperature changes, flexure, settlement, or overloading of the structure. Some cracks are harmless and have no adverse impact on the structure other than to mar its appearance. Some, however, leak or even threaten the building’s structural integrity. Pressure injection of cracks in concrete or masonry structures can be accomplished by one of these methods:
Is a permanent fix since the resin penetrates deeply into the fault where it is not exposed to ultraviolet light or other elements. The high tensile and bond strengths of the epoxy resin discourages elongation of the crack, compressive and shear strengths are restored, and reinforcement is protected from corrosion.
HYDRO ACTIVE POLYURETHANE GROUT
Is a liquid polyurethane injection resin designed to seal leaks and fill voids in concrete and masonry structures. The grout, when mixed with a catalyst and injected, forms a tough rigid foam seal that cannot be penetrated by water. This grout is typically used to stop gushing leaks, fill voids, and rebuild old or damaged construction joints.
Designed for applications where voids have developed or structural members, such as precast planks, require reinforcing. Each application is analyzed to identify the correct grout material and pumping equipment needed.
