Hyload Hyproof Membrane
Of all the choices the owner/specifier has to make when designing a green roof, the choice of waterproofing is easy. The Hyproof membrane is a high performance Coal Tar Elastomeric Membrane (CTEM). Incorporating the modern benefits of DuPont's Elvaloy® and the time proven properties of coal tar pitch, Hyproof has passed the 2 year FLL root barrier test. You may view the test report here.

Besides the critical property of root resistance, the Hyproof membrane also offers:

  • Hot air welded seams for system integrity - no lap adhesives that can be attacked by chemicals or roots.
  • Extreme chemical resistance
  • Mold, rot, and mildew resistant
  • Puncture Resistant
  • Unaffected by ponding water - can be warranted on zero slope


  • The Hyproof membrane, along with our full line of accessory products, will provide the optimal long-lived waterproofing choice for any green roof system.
