"We don't stop until the water does!"

20 Year Fully Transferrable Warranty

What is crack injection?

Crack injection is when a resin (polyurethane or epoxy) is injected into a crack or empty space in a concrete foundation under pressure. Polyurethane is flexible and is used to stop water leaks, while epoxy is a glue used to bond sections of a wall back together as a structural repair.

Many home owners use patching compounds like hydraulic cement to stop leaks, with limited or temporary success. The moment the wall shifts, the rigid patch cracks and leaks again. Another poor repair method is injection using surface mount ports and a hand operated dispenser to "fill" the crack with epoxy or polyurethane. We fix many of these so called repaired cracks because there is no way to know if the crack has been filled, and very often it hasn't. Small cracks cannot be properly repaired with this method, and large cracks are more likely to shift, thereby breaking an epoxy 'seal'. Many home builders use this method because they can get someone in to do it inexpensively and it can usually get past the two year "New Home Warranty" requirements. It's not until the Warranty is expired that the crack starts to leak again, often after the home owner has spent tens of thousands finished their recreation room.
