Blackline is an extremely robust unreinforced damp proof membrane, designed to withstand the rigours of a busy site. Site preparation will determine if protection is necessary. If protection is required a suitable Geotextile, sand or concrete blinding may be used.
Blackline meets the requirements for a polyethelene DPM, as set out in approved documents C of the Building Regulations. Due to the addition of carbon black, Blackline will last extremely well if exposed to Ultra Violet.
Blackline should be installed by Monarflex Geomembranes approved installation teams and lapped with a compatible DPC to maintain waterproofing continuity across cavity walls. Where possible all laps should be welded.
