It is a one component hydrophobic polyurethane grouting material, formed by the reaction of composite polyol and isocyanate,and sealed by isocyanate reacts quickly when it meets water, solidifies and expands to seal cracks, then achieving the effect of rapid water sealing.
Injunct Bond (PU 1K) is hydrophobic single component polyurethane. Upon contact with water, Injunct Bond (PU 1K) reacts to closed cell rubber-like foam while expanding its volume up to 27 times. The reacted material does not shrink or swell. Depending on the pressure of injection, Injunct Bond (PU 1K) reacts to a very dense material or Foam.
Single-component, easy mixing, and reliable performance.
Forms a strong bond with concrete and other surfaces.
Negative side application possible
Repels water, making it ideal for wet conditions.
Solvent free.
Excellent elongation creates tight seal in moving cracks.
Sealing cracks, honeycombs, and joints in concrete structures, including basement walls, tanks, and slabs.
Ideal for sealing leaking cracks in subterranean pipes, tunnels, sewers, manholes, and subway systems.
Sealing cracks and defects to prevent leakage under high hydrostatic pressure.
PU grouting works by injecting a specially formulated polyurethane resin into cracks or gaps in concrete. The resin expands and hardens, filling the voids, sealing the cracks, and strengthening the structure.
Yes, PU injection is highly effective for sealing and repairing various types of cracks, including those caused by water leakage, structural movement, or foundation settlement.
When applied correctly, PU injection grouting can last for many years, providing a permanent solution to water leakage and structural issues.
