 | | Z-LED SOLUTION GIVES TWO FOR ONE | | | Z-Led Ltd | | 03/11/2006 | | | A solution to the issue of addressing potentially harmful ground gases from penetrating brownfield developments has been developed by Z-Led Ltd.
The company's new PROTECT GDB10 Gas and Damp Barrier not only stops any methane, carbon dioxide and radon from entering the building, but also provides an effective damp-proof membrane. When installed with Z-Led's Cavity & Slab Edge Protection System, the GDB10 membrane provides a continuous barrier for protection of buildings against both gas and damp at ground level. When used as an oversite membrane below floor slabs or suspended floors, it provides a complete solution in line with Building Regulations Part C and BRE Report BR 414 2001 Construction of buildings on gas contaminated land.
The multi-layer reinforced polyethylene/polypropylene membrane with integral continuous solid aluminium foil is supplied with full fixing instructions. Tough and durable, Z-Led PROTECT GDB10 provides excellent tensile strength and enhanced puncture and tear resistance, yet it is easy to cut and, at only 15kg/roll, lightweight to handle. Each roll is 40m x long and 2.5m wide.
Matt McAndry, Z-Led Senior Product Manager explains, 'Harmful soil gases such as, methane, carbon dioxide and radon can enter properties through routes including cracks in floors and walls, construction joints and wall cavities. These have to be addressed to ensure compliance with Approved Document C, which states that 'reasonable precautions shall be taken to avoid danger to health and safety caused by contaminants on or in the ground covered by the building or any land associated with the building'. This is on top of other requirements for protecting the building from damp.'
The Z-Led PROTECT GDB10 is complemented by a range of accessories to ensure effective installation of the membrane, including Slab Edge Protection Trays, Joint Protection Tape, and Universal Pipe Seals. A range of sub floor depressurisation products is also available to ensure effective ventilation of gases from below suspended floors.
