• Excellent adhesion to dry and wet substrates.
• Remains flexible at extremely low temperatures.
• Cured resin remains stable and does not shrink over time.
• Cured gel is chemically inert and non-hazardous to environment.
• Resistant to high hydrostatic pressure and forms a permanent seal.
• Cured gel is non-toxic and can be used in contact with potable water.
• Extremely low viscosity: Ability to penetrate fine cracks under pressure.
• The hardened gel/foam remains flexible: Can accommodate movement in concrete.
• Forms a permanent seal which is highly elastic and flexible: Can accommodate movements in concrete.
• Form a hydrophobic foam when it meets water in the cracks or fissures to force the water out off the structure.

iNJEKT PU30 is a 2-component low-viscous Polyurethane-based injection resin used for grouting, and sealing of water-bearing cracks and fissures in concrete and brickworks. The resin is completely free of solvents and starts to react and harden to form a flexible and elastic gel when both the components are mixed. In presence of water, the mixed resin foams to form a flexible seal. iNJEKT PU30 should be used is used in conjunction with iNJEKT PU20 for stopping the flowing water.

iNJEKT PU30 has been designed to provide a permanent flexible seal in water-bearing cracks and fissures in concrete, blockwork, and brickworks. This can also be used to seal dry cracks and joints in concrete where movement is expected. It is also used for injecting non-re-injectable hoses used in concrete joints.
