What is polyurethane injection?

Polyurethane injection is performed to seal active leaks, prevent moisture migration and to protect structures from corrosion and water related decay. Polyurethane injection technology is superior in most wet and actively leaking environments. There is an injection solution to most concrete crack related problems.

Can polyurethane be injected?

Molten polyurethane is injected into a closed mold at high pressure. The high-pressure forces the polyurethane to completely fill the mold cavity. The resulting product is net shape, or near net shape, directly out of the mold. Injection molding is traditionally thought of for high-volume production.

How does polyurethane injection work?

Polyurethane Injection grouting is a waterproofing technique that involves creating a polyurethane mixture whereby when this mixture is inserted with pressure into the cracks of a structure, the mixture will react and in turn expand and toughen. It is used to stop water flowing through structural joints and cracks.
