Elastoplastomeric compound (BPP) reinforced in glass clot and polyester glass fabric.

abedex® unigum Dual Reinforced is a robust and stable membrane due to the incorporation of two reinforcement materials; the membrane strength from the polyester and the stability from the fiberglass mat. The upper surface of the membrane receives an evenly distributed sand finish which allows the membrane to be unrolled easily during the installation process. The underside of the membrane receives a sacrificial polyethylene film, Flamina and then the membrane is embossed. The embossing allows for rapid burn off of the polyethylene film when the membrane is being installed by gas torch installation.

  • abedex® unigum Dual Reinforced bitumen waterproofing membranes possess excellent ageing resistance and dimensional stability making them suitable for solving the most difficult waterproofing problems on; flat, sloping and pitched roofs, reinforced concrete, prefabricated concrete, masonry cement, metal and timber decks and terraces, with or without thermal insulation and for renovation purposes.


  • 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.
