THE FUNDAMENTALS RIGHT WITH EPOXY CRACK INJECTION
When a structural repair is required, conditions that cause the crack must be corrected prior to proceeding with the epoxy injection. If the crack is damp and cannot be dried out, an epoxy crack injection should be considered. Cracks caused by corroding reinforcing steel should not be repaired by epoxy injection because continuing corrosion will cause new cracks to appear.
The correct viscosity of the epoxy will be determined by repair experts, and will depend on the crack size, thickness of the concrete slab and crack access. Before using epoxy injection, DryShield will determine the cause of the crack and the need for a structural repair. If the crack is not structural integrity of the structure, injection with polyurethane or other nonstructural materials may be a more suitable choice to fill the crack.
The fundamental steps for successful low-pressure crack injection.
Keep in mind, that the kind of epoxy or polyurethane used and the time required for injection will vary with each job depending on the crack width, wall thickness, and other circumstances.
You can install injection ports that serve as helpful entryways for getting the repair material into the crack. They remove the need to drill into the concrete, reducing time and cleanup.
Sealing the surface using an epoxy adhesive to seal on top of the exterior ports and exposed cracks is another alternative. The paste cures in a few minutes to provide a surface seal with excellent bonding that holds up under injection pressures.
Last but not the least, you can inject the crack. Begin by injecting at the lowest port on the wall and continue until the epoxy or urethane begins to ooze out of the port above it. That’s the visual sign that the crack has been packed to that level. Cap the first port with the cap provided and go up to the next port, repeating this process until the entire crack is packed with epoxy.
Finally, remove the ports. Allow time for the epoxy or polyurethane to cure and pierce into the cracks. The injection ports can then be detached by striking them with a trowel or hammer. If looks are an issue, the epoxy surface seal can be chipped away or ground off with a sanding disk.
