The abedex® V-SR membrane are available in 3 mm and 4 mm thicknesses on a 10 m roll. The membrane manufacturing processes uses polymer modified bitumen reinforced with a composite reinforcement. This ensures a good quality membrane that has high elongation and stability across the defined temperature range.

The upper face of abedex® V-SR membrane are coated with a sand finish which allows the membrane to be unrolled easily during the application and provides a prepared surface for the application of a aluminium reflective coating to the upper membrane side.

The underside of the membrane is lined with Flamina, a sacrificial polyethylene film. It is embossed with small squares which assist in the rapid burn-off of the Flamina as an indicator that the correct melting point for adhesion to the primed substrate ensuring a reliable installation.

  • abedex® V-SR membrane can be used as a single layer system or as part of a multi-layer in both the refurbishment and new building works market
  • On all sloping surfaces: flat, vertical and curved
  • Walls, foundations and concrete roofs


  • 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
