Phthalate-free, fast-acting, 2-part, pre-catalyzed, rigid foam polyurethane injection system for structural injections requiring high compressive strength
RockStab resins are phthalate-free, 2-component injection resins consisting of a resin and a hardener that are pumped in a 1/1 mix ratio. After mixing the two components in a 1/1 ratio through a special mixing head with static mixer, the resin hardens into a hard foam, a very hard foam, or a hard plastic, depending on the type of Rockstab used.
Faster response times can be obtained by using an optional accelerator.

• Additional Information

  Rockstab is supplied in a 2-component set:
  • A-part: polyol blend
  • B component: isocyanate
  • Mixing ratio: 1/1 volumetrically
  
  Use
  • Filling of large voids, cracks and fractures
  • Consolidate rock formations
  • Grouting of injection anchors
  • Fastening rock bolts and rock anchors
  
  Benefits
  • ADR free transport
  • Phthalate-free resin, REACH compliant.
  • Solvent-free
  • Choice of different expansion ratios and compressive strengths
  • User-friendly: simple mixing ratio 1/1 (5% deviation is allowed)
  • Response and cure times can be easily controlled using an optional accelerator.

CYH-500 is a hydrophobic grout based on polyurethane.
Upon contact with water, CYH-500 reacts to closed cell rubber-like foam while expanding its volume up to 27 times. The cured material is of a constant volume. Since water is not a component of the foam structure, the cured material is essentially not affected by water or dryness. The reacted material does not shrink or swell. Depending on the pressure of injection, CYH-500 reacts to a very dense material or foam

  • Concrete joints, Limestone, Brick construction
  • Pipe intrusions, Waste water tanks
  • Tunnels, Dams, Subway(Metro), Sewers, Manholes, Utility boxes, etc.
  • Soil stabilization
