FATRAFOL 813 is based on plasticised PVC with embedded glass fleece. It has a yellow signal layer that makes mechanical damage easier to identify. It is designed for sandwiched waterproofing of structures against aggressive, pressurised and seepage water, in environments where contamination by petroleum substances may occur.
Dimensionally stable even at high external temperatures.
Serves as an indicator of membrane damage and eliminates the risk of incorrect membrane installation.
Thanks to the glass fleece, the membrane is stronger, more dimensionally stable and better resists mechanical damage.
Excellent chemical resistance to waters contaminated with petroleum substances.
Compatibility ensures the mutual fit of all system components.
Verified by testing and by real-world construction experience.
