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

abedex® FS-R membrane is manufactured from a compound of distilled bitumen elastoplastomeric and 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 upper face of the membrane is treated with a sand finish, which prevents problems when unrolling the product. The lower face is covered with a sacrificial polyethylene film and the roll is then embossed. 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 can be used as a single layer waterproofing system or as part of a multi-layer built up waterproofing system


  • 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
  • Protection coating or overlay to be determined by a professional with a.b.e.® technical assistance
