These corner ports are specifically crafted for attaching to corner cracks in concrete walls using Polygems LCR Epoxy Repair Paste. Once secured, they facilitate the injection of Polygem LCR Injection Epoxy into the crack. Each port boasts an angled base tailored for corner crack placement and comes with an integrated cap. The cap attaches to the port once the injection epoxy has reached the level of that port. This design ensures the epoxys upward movement within the crack can be monitored, allowing sequential filling from the bottom upwards. Each package provides 7 corner ports along with 7 caps. After curing, the ports may be removed by striking them with a hammer.
