is the ideal waterproofing system for bituminous roofs. Its advantages include, its flatness (zero profile) and high degree of elasticity.

  • No need for complicated joints thanks to the "sandwich" method.
  • Shearing or traverse movements are taken up entirely by expansion area.
  • Manufactured according to ISO 9001 / EN 29001.
  • Manufactured from an inert high grade elastomer.
  • Can be used with asphalt, bitumen, coal tar pitch, hot rubberized asphalt, modified bitumen, spray polyurethane foam and epoxy resin.
  • Available with metal flanges for connections with metal flashing.
  • Custom made details to suit site conditions.
  • On-site vulcanisation is possible.

    Vulcanisation means monolithic seams
