Introduction


A902 Single Component Hydrophobic PU Grout (PU Foam) is designed to stop water leaking through the crack. When liquid urethane reacts with water, it begins to foam and expand to fill the crack. Once the urethane has foamed and expanded inside the foundation crack, water cannot leak into the construction.


 


A902 PU Grout is a single component hydrophobic polyurethane injection resin, which after reaction with water, can expand rapidly to form permanent seals.


 


 


Properties



  • Short waiting times during the works. Very reactive with water and can complete foaming process within 1~3 minutes.

  • Better crack penetrstion due to low viscosity.

  • Better sealing due to great adhesion with concrete.

  • High resistance to aggressive chemicals. Can retain its properties when mixed with weak base or weak acid, even with seawater. Permanent repair and long-term flexiblity. 


 


Characteristic



  • Single component formula

  • Very low viscosity

  • Reacts with water to foam in 3 minutes

  • Repairs concrete cracks

  • Stops water leaks
