Two Component, Acrylic Modified Cementitious Waterproofing Coating

TREMproof RT Plus is primarily used for internal waterproofing of concrete tanks. It is a two component, acrylic modified cementitious coating that can be fully immersed. TREMproof RT Plus can also be used as a negative barrier to mitigate against water ingress in hydrostatic conditions.


Typical applications for TREMproof RT Plus include:
  • Water Retaining Structures
  • Retaining Walls
  • Planter Boxes/Green-Scapes
  • Under Tile Waterproofing (external only)
  • Suitable to be used as a negative barrier to mitigate water ingress in hydrostatic conditions.
