We offer a polyurethane crack injection service for those pesky leaky basement walls.  It consists of a polyurethane foam that expands to seal off the crack from water that is trying to get in.  It is by far the simplest, most cost-effective way to seal leaky cracks in poured basement walls from the inside of the house.  Please contact us today to schedule a repair to stop that water leak and keep your basement like its supposed to be. Dry!  Below are some facts on the system that we utilize:


  • Seals seeping or mildly leaking cracks


  • 400% elongation provides a flexible seal for moving cracks


  • Can also be used on dry cracks


  • Expands to fill voids and close off the back of the crack


  • Expanding nature makes it suitable for sealing cracks in solid masonry


  •  Fast reacting - reaction begins within 1 minute after exposure to moisture; expansion may be completed within 3 minutes (depending on the amount of moisture and the ambient temperature).  


  • Non-shrinking hydrophobic formula with the elongation and flexibility of a hydrophilic resin 


  • 20:1 expansion ratio (unrestricted rise) means less material needed
