Hydrophobic Waterproof Pu

Having successful business expertise, we are engaged as manufacturer, supplier and exporter of Hydrophobic Waterproof PU in Seoul, Seoul, Korea South. CYH-500 is a hydrophobic grout based on polyurethane. Upon contact with water CYH-500 reacts to closed cell rubber-like foam while expanding its volume up to 30 times. The cured material is of a constant volume. Since water is not a component of the foam structure, the cured material is essentially not affected by water or dryness. The reacted material does not shrink or swell. Depending on the pressure of injection CYH-500 reacts to a very dense material or foam.

Areas of application include:
i Defective concrete (cracked or honeycombed)
i Concrete joints, Limestone, Brick construction
i Pipe intrusions, Waste water tanks
i Tunnels, Dams, Subway(Metro), Sewers, Manholes, Utility boxes, etc.
