What is PU Injection Resins ?

Unlike Epoxy Grouts, Polyurethane Grouts are not intended for Structural repairs, but used primarily for arresting leakages in waterproofing Industry. PU grouts also allow for future movements at joints locations.

This liquid PU based resin reatcs with water present in the crack and substrate creating a chemical reaction, expands to form a gel or foam material to fills the voids and cracks Expansion of PU grout forms tight impervious seal against substrate sides, stopping water access or leakage through a joint or crack.

Features of PU Injection Resins

  • Available in several formulations.
  • Excellent movement capability.
  • Low viscous formulation penetrates deep in to cracks.
