Description
CYH 500
SINGLE COMPONENT HYDROPHOBIC TYPE PU
Description
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 27 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.
Uses
Areas of application include:
• Defective concrete (cracked or honeycombed)
• Concrete joints, Limestone, Brick construction
• Pipe intrusions, Waste water tanks
• Tunnels, Dams, Subway(Metro), Sewers, Manholes, Utility boxes,
etc.
• Soil stabilization
Advantages
• Negative side application possible
• Deep penetration into very small cracks
• Foam increases in volume to fill cavities and voids
• Excellent bond to surfaces
• Good adhesive strength, tolerant of movement
• Inert after curing, constant volume, no shrinkage
• Dose not create new cracks
Important Notes
• Minimum ambient and substrate temperature is 5℃.
• Material shall be store in a dry cool place.
• Good storage stability for unopened containers at 15℃~30℃
CARBON
FIBER
Advanced Reinforcement
Solution
It is cutting edge new material for loadbearing capacity
improvement and seismic retrofit, and have very strong tensile
strength than steel, and have been used for repair and
reinforcement of concrete structure since
1990s. Specially quake-prone countries like Japan have
used carbon fibers lately and largely.
Features
• High reinforcement with more than 10 times tensile strength than
steel
• Reinforcement with the less quantity than steel.
• Light weight : specific gravity is one-fifth of steel
• No deterioration by external factors like water, base, acid or
ultraviolet rays
• Easy to work in small place because whole process by using
hand
• Site workability is outstanding
