VPU-2 Hydrophobic Oil Grouting Materials for Waterproof Plugging &
Reinforcement
Repair of Concrete Leakage
Introduction
VPU-2 is one component hydrophobic PU grouting material, it reacts with water and expand to be a foam
does not dissolve in the water. Not only used for waterproof plugging, but also with effect of
reinforcement.
It is widely used in subway tunnels, water conservancy and hydroelectric power, basement parking, sewage etc
for waterproof plugging and reinforcement projects.
Characteristics
1.With good hydrophobic properties, high chemistry stability.
2.With larger Penetration radius and solidification volume ratio,
react with water quickly with large expansion
pressure, pushing the liquid to the depths of crack and expand to
form a tenacity consolidation.
3.Resistance of acid, alkali and organic solvent, better resistance
of chemical corrosion;
4.Coating smooth, wear-resisting, no mildew ;
5.Excellent adhesiveness with concrete base and other construction
materials;
6.Viscosity and cure speed can be changed according to the
requirement of projects.
