Install Injection Ports:
The surface harbors lend a hand in the entry of repair material into the fissure and it eradicates the requirement of drills, lessen the labor time and cleanup. The pedestal of the port is directly placed above the fissure and bond the surface with the help of epoxy paste.
Seal The Surface:
Make use of an epoxy bonding agent to close the surface ports and uncovered cracks. The paste hardly takes nearly 20 to 45 minutes to supply the surface a seal with the admirable bond that seized under the pressure of injection.
Inject The Crack:
Start injecting the epoxy at the lowest port and continue until it begins to come out from the above portion of port and that gives the visual indication that the crack has been filled up to that level.
Remove The Ports:
Place the epoxy or polyurethane at room temperature for 24 to 48 hours to heal and infiltrate into the cracks, and afterward, the injection ports will be separated by striking them with a trowel or hammer.
