Protech VOC Flex, supplied by A. Proctor Group, is a multi-layer flexible reinforced VOC Hydrocarbon/ Chemical Barrier suitable for use on brownfield sites that require protection from dangerous contaminants such as hydrocarbons.
Protech VOC Flex has been extensively tested by independent testing laboratories and fully complies with the requirements of BS8485:2015 where methane permeability must be <40ml/m2/day. As a minimum VOC membranes must be tested against the 9 chemicals for vapour permeability (ISO 15105-2) and after immersion (EN14414). The 9 chemicals included are: benzene, toluene, ethyl benzene, m.p xylene, hexane, vinyl chloride, tetrachloroethene (PCE), trichlorethene TCE, and naphthalene.
Protech VOC Flex has been developed to ease installation on sites, due to the flexibility of the membrane. A wide range of accessories to complement this membrane are also available, including Prefabricated Corners, Starterband and Top Hats.
