After an initial evaluation of the problem, CRSI can repair cracks by use of epoxy injection, in which epoxy material is injected into the prepared crack until refusal. Once the material has cured, the repair area can be coated to closely match the surrounding area, or to waterproof against further water intrusion. Larger cracks and spalls, where the concrete has chipped into small pieces leaving a hole, are repaired by “stitching” the crack with material and then applying the epoxy to fill the crack.
Where the area in question has developed a degradation of the underlying rebar which holds the concrete together, CRSI can remove the bad concrete to expose the area, drill holes to re-set the rebar, and inject material to anchor the rebar into place. This process significantly strengthens the structure underlying the concrete. Material can then be replaced over the rebar and the area coated.
Joint repair is needed when the original material that was installed between sections of concrete has deteriorated or been destroyed. CRSI cleans and prepares the joint, removing loose debris, then prepares the joint to receive the appropriate material to seal.
