A good number of cracks in concrete, masonry and stone pose no structural threat to the member or the structure. However, the mere sight of a crack in an overhead beam or support column will send the general public into an uneasy nervousness. The repair of these cracks with conventional epoxy pressure injection might result in a repaired crack, but unless the completed repair is painted or coated, the resulting esthetics are often far worse than the crack itself.
Pressure injection requires the crack to be sealed with a material, usually a paste epoxy, that will tenaciously bond to the surface of the member being injected. This tenacity is a requirement to contain the pressures exerted on the repair resin introduced into the fracture. Removal of this sealer epoxy is most often performed by grinding the material off the surface with a rotary grinder; and most often mars the surface in such a way the defacing leaves little doubt a repair has been performed. The removal of the crack sealing material can be impossible on fluted panels, decorative concrete, statues and historic members. Depending on the severity of the cracking, or the "in your face" location of the crack, the fracture often leaves designers with little choice but to do nothing, or remove and replace the member. Tecvac, Inc. has two solutions for this delima: CleanSettm and CrackMasktm. (Please visit our website at www.tecvacinc.net)
Repair of historic textured/aggregate concrete using CleanSettm. After the repair is made, the proprietary setup materials just peel away.
After restoring the fracture with CleanSettm, CrackMasktm was applied to the crack on the left. Even close up, the repair and the original crack are hard to detect.
