CYH-202
Single Component Semi-rigid Polyurethane
Description
CYH-202 Semi-hydrophobic Polyurethane Grouting is used to stop leaks and fill underground voids.
CYH-202 is a polymer solution which cures when reacted with water, CYH-202 can not only stop the water, but also it can stop or slow the deterioration of steel bar or other internal features of the concrete. This success is due to the placement of CYH-202 throughout the depth of the crack.
Uses
Areas of application include:
  • Retaining walls
  • Bathrooms
  • Floor slabs
  • Water tanks
  • Terraces and balconies
  • Patios
  • RC gutters and planter boxes
  • Swimming pools
  • Suspended floors
  • Basements and fountains
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
  • Dose not create new cracks
