How does MasterInject 1230 IUG work?

MasterInject 1230 is a one-component polyurethane hydrophobic injection resin with an optional accelerator to control setting times.  It reacts with water to form a resilient and flexible plug that seals leaks in concrete structures.  The required rate of expansion and reaction to water can be altered by temperature or by the amount of accelerator used. 

Recommended uses:

  • Horizontal and vertical surfaces
  • Interior and exterior
