Concrete Crack Injection - Urethane
Urethane crack injection is an effective way to seal cracks in a concrete structure to stop the flow of water. Urethane is also used for injection tubing systems, which are installed at concrete boundaries between new and old slabs.
In areas where water is leaking through the crack an expanding urethane resin is injected using pressures up to 1800 psi. This resin is water-activated and will expand until the crack is sealed.
