Hot melt roofing systems

When to specify...

The Bauder Hot Melt Structural Waterproofing System is ideally suited as a waterproofing system beneath paved or ballasted surfacing, car parks, podiums, plazas, green roofs and substructures. Our hot melt system holds fire classification BROOF(t4) for compliance with building regulations under TS 1187 test method 4 for external fire exposure to roofs.

Key features

  • Seamless application provides monolithic waterproofing
  • Membrane remains 'live' throughout its life
  • Durability to match expected life of building
  • Excellent flexibility and adhesion characteristics


  • Infills minor cracks eliminating possibility of water ingress
  • Minor penetrations and cuts will self heal
  • Expect no future replacement costs once installed
  • System can be installed in temperatures as low as -18⁰C
  • Can achieve fire rating of BROOF(t4) with a wide variety of hard and soft landscaping
