How to install Hydrotech Hot Melt Waterproofing

Posted by david.luukas

Alumasc has recently completed a new step-by-step guide to installing the Hydrotech MM6125 Hot Melt Waterproofing system.

Hydrotech is a 6mm thick rubberised bitumin blend which is heated and then combined with a polyester fleece and protection sheet to form a weatherproof layer.  It is used for zero falls waterproofing on inverted green roofs, blue roofs and hard landscaped podium structures in new build applications and is ideal for application over complex roof details and penetrations.  Hydrotech has a 100% bond to the roof, so water cannot track beneath.

The video illustrates that Hydrotech is fast and simple to apply due to the fact that each individual part of the installation process is covered, with particular attention being given to:

  • hydrotechVideoHealth & Safety
  • Required tools
  • Heating to working temperature
  • Bond test
  • Upstands
  • Detailing
  • Pipe penetrations
  • Membrane application
  • Reinforcement
  • Protection sheet
  • Depth gauge
  • Electronic leak test
  • Insulation
  • Separator sheet
  • Paving supports and slabs
