CY 505 (PU GROUT)

New!

Feature:

With its low viscosity property, it penetrates into leakage sections in tiny cracks and provides perfect water stop performance.
After hardened, it provides excellently higher compressive, adhesive and tensile strengths that the mechanical strength of conventional concrete structures.
Since its pot life is sufficient (about 30-50 minutes) when the base agent and the curing agent are mixed, injector, it can be injected by the single component injector (CY-800 M1/M2, CY-1000).

Advantages:

Underwater injection approved
Good elastic strength, tolerant of movement
Inert after curing, constant volume, no shrinkage
Foam increases in volume to fill cavities and voids
Excellent bond to wet surfaces
Negative side application possible
Deep penetration into very small cracks
Does not create new cracks

Description

CY-505 is Double component type hydrophobic polyurethane resin that cuts off water from cracks and reinforces the maintenance works on concrete structures, subways and tunnels.
It is a low expansion water stop reinforcing agent of which the water reaction expansion ratio is minimized.
Compared to conventional polyurethane water stop materials, it is stronger and its hardened foam is more rigid.
It does not generates defects by foam deformation and it provides virtually permanent water stop effect.

Areas of application include:

Defective concrete (cracked or honeycombed)
Tunnels, Dams, Subway (Metro), Sewers, Manholes
