Polyurethanes from Premco stop water leaks.
Foundation wall crack leaks are best stopped with polyurethane foam concrete crack injection. Liquid urethane plugs the foundation crack completely. It foams and expands inside the crack. It’s filled with expanding foam to avoid water leaks. Water will stay outside the basement wall and not enter.

The average 8′ foundation crack takes an hour to fix. The foundation fracture can be expanded without drilling or chiseling. Low-viscosity polyurethane can easily block basement water leaks through hairline cracks.
