Non-Structural Wet & Leaking Foundation Cracks - Polyurethane Concrete Crack Injection Kits

A foundation wall crack that has developed simply because of concrete shrinkage or freeze-thaw temperature changes or a minor ground settlement and has since subsided.

NextStar typically recommends an injection of polyurethane foam if the foundation wall crack is simply wet and leaking and poses no structural risk to the foundation.  Polyurethane foam reacts with water and expands throughout the crack or void thus filling and sealing all the way to the outside.  The expansion ability of polyurethane foam is the true benefit to a successful concrete foundation wall crack repair injection. Remember you are doing more than stopping water but preventing water from entering the concrete wall, this may cause more damage should it freeze and allow seepage into a living space causing mold issues. 

Our foundation crack repair products are available in user-friendly starter kits, which makes learning the various components much easier for anyone new to repairing foundation cracks. For experienced contractors, our products are available for individual purchase.


Leaking Basement Foundation Walls

The key feature of polyurethane foam injection is that it reacts with moisture and water, thus it fills cracks and voids in a cracked wall to stop leaks in your basement.
