PU Foam
CY-109
Gel Type Single Component Hydrophilic Polyurethane (Flexible PU)
Description
CY-109 is gel type hydrophilic polyurethane for grouting injection. It is used to stop leaks and fill underground voids.
CY-109 is a polymer solution which cures when reacted with water.
CY-109 can stop the water, it can stop or slow the deterioration of steel bar or other internal features of the concrete.
The success is due to the placement of CY-109 throughout the depth of the crack.
Uses
Areas of application include:
  • Bathrooms
  • Water tanks
  • Patios
  • Swimming pools
  • Basements and fountains
  • Retaining walls
