PU Foam
Single Component Hydrophilic Polyurethane
CY-101 Hydrophilic Polyurethane Grouting is used to stop leaks and fill underground voids.
CY-101 is a polymer solution which cures when reacted with water, CY-101 can stop the water, 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 CY-101 throughout the depth of the crack.
Areas of application include:
  • Bathrooms
  • Water tanks
  • Patios
  • Swimming pools
  • Basements and fountains
  • Retaining walls
  • Floor slabs
  • Terraces and balconies
  • RC gutters and planter boxes
  • Suspended floors
  • 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
