Surface Corner port application

Corner Ports for Non-Corner Wall Cracks "Previously" Repaired with Hydraulic Cement

A common question we receive from contractors regards normal (non-cornered) wall cracks previously "repaired" with hydraulic cement. Since the use of hydraulic cement only covers the crack, as opposed to actually filling the crack inside the foundation wall, it doesn't take long for leaking water to resurface. For such situations, injection with polyurethane foam or epoxy is possible. For such applications, the Corner Port may provide a better fit over the cement's rough texture - this option may help prevent the applicator from initially having to remove the hydraulic cement. Blitz powder can also be used seal port in place when a 5/8 pilot hole is drilled.

Example of using a corner port that is drilled in

Injection corner ports for low-pressure injection repairs in the corner or drilled injection locations.  Can be used with all Epoxy and Polyurethane products.
