PU injection, also referred to as polyurethane injection, is a method of waterproofing that uses expanding Polyurethane to block the water flowing through and the voids and cracks in concrete. This method can effectively address water leakage issues mainly when applied to the bottom of the leakage area or on the ceilings of the lower floors in the room where leaks occur. 


Polyurethane is extremely fast to set and can withstand even the slickest surfaces. The common cracks aren’t as large, and the attempts of these types tend to be smaller Polyurethane is superior to concrete that has slightly moved. The polyurethane-based material can be used to be able to seal quickly and effectively and keep water out.

  • Cracks and visible surface leaks must be sealed using fast setting Polyurethane to stop injection resin from spilling out of the damage.
  • Before injecting, the cracks must be cleaned out with clean water to get rid of dirt, dust salts, etc., from the damage.
  • The pumps used to inject the resin are to be flushed, and tools should be cleaned immediately following use before the resin is set.
