Foundation Crack Injection Ports & Caps (25/Bag)

The crack injection port fits into a 1/2″ diameter hole. It is used when a surface is too irregular to allow the use of a surface mounted port, or when a hole must be drilled to penetrate below contaminates that might prevent penetration of epoxy from a surface mounted port. The injection port can withstand injection pressures of 900 psi and for this reason is frequently used to inject polyurethane resins in 1/2” diameter holes. The ports & caps are sold in bags of 25 pieces.
