Formerly: MEYCO TSL 865 Admixture

What is the purpose of MasterRoc TSL 865?

  • MasterRoc TSL 865 is a single-component polymer powder for spray application onto soil and rock for reinforcement or weathering protection.
  • Improves ground stability and stand-up-time through good bond to most substrates, high elasticity and high tensile strength.
  • Sprayed concrete can be applied against the membrane as soon as it has set.

Recommended for use in:

  • Stabilization of soil and rock
  • A possible alternative to mesh/screen protection with or without the use of bolts
  • Preliminary slope protection binding the surface before the area is ready for sprayed concrete
  • Pillar/rib support
  • Helps to reduce hard-rock strain bursting
  • Rehabilitation of collapsed areas
  • Vent stopping
  • Water retention pond liners
