PRESSURE INJECTIONS
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;
EPOXY INJECTION
Most cracks in need of repair should be injected with an epoxy. Epoxy injection
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.
HYDROACTIVE POLYURETHANE GROUT
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.
CEMENT GROUT
Cement grouts are 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.
