Elastoplastomeric compound (BPP). The reinforced s made up of polyester un-woven fabric reinforced with fibreglass strands.

abedex® FS-R membrane is manufactured from a compound of distilled bitumen and elastoplastomeric polymers. After mixing, the characteristics of the polymers are dominant and are evenly dispersed throughout the matrix.

abedex® FS-R membrane has excellent stability at both high and low temperatures and possesses good longevity.

The embossing assists in the rapid burn off of the polyethylene film in the torching operation and allows good vapour diffusion.

abedex® FS-R membrane has slate granules applied to the upper surface of the membrane during the manufacturing process.

  • Normally used in an exposed waterproofing system.
  • The mineral surface should be used as the upper membrane in a two layer system acting as a capping or weathering sheet.


  • The substrate is to be clean, dry and free of any dust, grease, oils or loose debris. The substrate is to be of a smooth and even condition being free of protrusions or voids
  • Coves or fillets are to be installed at all internal angles
  • Screed to falls of 1:80


  • Apply bituprime primer on substrates to receive membrane
  • Allow to flash off or dry


  • Avoid rough handling, especially at low temperatures below 5 °C. Work must be stopped at temperatures below -2 °C
  • Our standard application of the membrane requires that the product be fully bonded by heat fusion to the primed substrate by heat fusion
  • If a two layer membrane system is to be fitted the upper membrane must be laid with staggered side and end laps
  • We recommend side laps to be minimum of 75 mm and end laps to be a minimum of 100 mm
  • A round nosed trowel and gas torch to be used when installing the membrane ensure adequate bonding of the laps
Mineral Slate Protection
  • Slate granules are applied during the manufacturing process to the weathering surface of the membrane. An attractive finish results and reduced maintenance costs can occur. There is the further value of protection from the damaging effects of ultra violet rays
