Elastoplastomeric compound (BPP) reinforced in reinforced polyester
The membrane is manufactured from modified bitumen reinforced with a non-woven polyester fabric.
abedex® unigum Mineral Slate incorporates a slate granule imbedded into the upper surface of the membrane producing an aesthetically pleasing, low maintenance waterproofing material. It should be noted that this membrane should not be used as a primary waterproofing membrane, but rather as a capping sheet in a two layer system.
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 torch application.
Uses
- Normally used in any exposed waterproofing system
- The mineral surface should be used as the upper membrane in a two layer system acting as a capping or weather sheet
Application
SUBSTRATE PREPARATION
- 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
PRIMING
- Apply bituprime primer on substrates to receive membrane
- Allow to flash off or dry
APPLICATION/BONDING
- 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
