Crack injection

By applying unique solutions to increase the safety and longevity of our environment.

Crack injection is used to stop water leaks through buried structures. Crack injection is typically performed using single component polyurethane grouts. For exceptionally large cracks with high water flows, plural component polyurethane grouts can also be used.

Crack Injection Methods

Whether or not a crack is wet at the time of repair is the most important driver of repair method choice. The other driving force is whether or not the entire length of the crack is accessible.

For cracks which are dry and accessible, the easiest way to perform crack injection is to seal the surface with fast-setting epoxy. Injection ports are embedded in the epoxy. After the epoxy cures, the crack sealing material is injected directly into the crack.
