Crack injection can be performed on cracks in structural and non-structural concrete with appropriate materials chosen based upon the type and width of crack. The practical benefit of injection repair is that it can most often be performed from the interior of existing structures, thus avoiding costly problems such as exterior excavation. Enhance ICD repair systems always employ the use of topical concrete hydration and desiccation technology to maximize the bond of injection materials and to condition the concrete
Where is injection repair used?
Leaking Foundations; Water Containment Structures; to protect Structural Concrete Members; Roofs; Retaining Walls and more ...
Suitable for many types of repair, injection is typically used for cracks that can be hairline up to ½” in width.
Urethane, Polyurethane or Epoxy and other injection materials are used to fill the entire length and depth of the crack void in most instances. Water leaks, usually from and exterior source such as run-off, poor landscape drainage or water table issues, are permanently stopped at the site of injection. Some processes require the injection material to be installed directly into the surface of the crack, while others are installed deep into the the crack or void by intersect-drilling.
Once injected the repair material will cure within the void space. Some expand rapidly, then cure, creating a permanent seal. Injection material selection is critical. Is there a possibility of movement in the repaired concrete? Then, a rigid Epoxy will not be the answer. Always get competent advice.
