The Foam Injection Ports are designed to make crack repair in pools and concrete structures quick, precise, and reliable. These surface-mounted ports provide a secure base and wide opening to minimize back pressure and prevent blowouts during polyurethane foam injections. Compatible with AquaBond’s PFK-377 and DMK-377 kits, they are ideal for repairing cracks in concrete, gunite, shotcrete, and fiberglass pool walls and decks.
