Duroflex Tank

Duroflex tank is a two component polymer modified contentious coating designed for waterproofing concrete and masonry surfaces in a variety of applications. Applied by roller, brush, trowel or spray methods once cured Duroflex tank provides a protective barrier to concrete surfaces against salts, chlorides and carbonation. Designed for use in permanently wet and damp conditions including applications such as:

  • Concrete walls and surfaces in subterranean areas
  • Water features, tanks and fish ponds (able to be tiled over)
  • Protection of concrete columns, pillars and general surfaces against chloride attack and carbonation
  • Coating of concrete water retaining channels, pits and drains
  • External waterproof protection on concrete
  • Recommended to overcoat with Durotech UV protective coatings)

Based on unique cross linking polymer technology, Duroflex tank displays outstanding adhesion properties over numerous building substrates including concrete, masonry, renders, screeds and cement based mineral surfaces. No priming is required as Duroflex basement bonds to clean pre-dampened surfaces free of surface water. For applications where finishes need to be applied over this membrane, tiles, renders, textures and solvent free paints are able to be directly applied to the cured Duroflex tank surface.


  • Handles ponding and permanently wet conditions,
    will not re-emulsify
  • No primer required, bonds to damp surfaces
  • Flexible with good elongation properties
  • Can be applied on vertical and horizontal surfaces
  • Resistant to chloride attack, carbonation and salts
  • Bonds to concrete surfaces after 48 hours of application,
    bonds to renders, screeds etc after 16 hours of application
  • Compatible bonding properties for tile adhesives, screeds,
    renders and texture coatings
  • Suitable for internal and external surfaces
  • Suitable for immersed and underground areas
