• Cured foam remains stable.
• Excellent adhesion to wet substrate.
• Resistant to high hydrostatic pressure.
• Rapid expanding foam with a dense cell structure.
• Pot life can be reduced by increasing the dosage of the catalyst.
• Cured foam is non-toxic and can be used in contact with potable water.
• Foaming reaction starts only when the mixed resin is in contact with water. Unreacted mixed resin will have a pot life of around 6-8 hours ensuring low wastage of mixed material

iNJEKT PU20 is a 2-component, low-viscosity, solvent-free water-reactive, fast-foaming polyurethane injection resin.
The product consisting of a base (Part A) and a catalyst (Part B), reacts with water to form a rapidly expanding dense and flexible foam to immediately stop the ingress of flowing water though a concrete crack in any other or tunnel construction.

iNJEKT PU20 has been designed for immediate stoppage of flowing water from concrete cracks or joints by forming a temporary seal prior to the injection of a permanent polyurethane grout like iNJEKT PU30 (Flexible gel). It is also used to fill cavities brickwork and concrete.
