Product Description

Polyurethane Waterproofing Material

High Strength Polyurethane is a hydrophobic polyurethane resin of two package type. It is widely used in maintenance works for subways, tunnels and concrete structures. Basically, it cuts off the water from crack for excellent reinforcement. High Strength Polyurethane is specially formulated for low viscosity so that it can easily penetrate deep down into the tiny leakage sections for perfect water stop performance. Ideal for both wet and dry crack repair works, this product comes with both curing and base agents.

CY-505 is two 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.

Key points:

  • Ideal for pore filling, water stop and concrete strengthening
  • Provides excellent adhesive, compressive and tensile strengths after hardening
  • A low expansion water stop reinforcing agent

Areas of application include:

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


  • Reinforcement of deteriorated concrete structure
  • Repair concrete cracks for water-stop
  • It is possible to use at dry and wet concrete cracks
  • Deep penetration in to finest cracks
  • Inert after curing, no shrinkage
  • Does not create new cracks.
