Description: The Powerbase Radon Red 300mu Gas Barrier Membrane - 25m x 4m is a BBA certified barrier membrane that is specifically designed to give protection to buildings, against the naturally occurring gas, radon. The membrane is bought in rolls so that it can be joined on-site and is recommended to be joined with double-sided butyl tape. Powerbase Radon Red 300mu Gas Barrier Membrane - 25m x 4m is suitable for use under foundations when constructing most buildings and is fitted in a similar way to a damp-proof membrane. However, more attention should be paid to ensure that the gas barrier membrane is securely sealed in all areas, in order to give effective protection against radon. The membrane is made from robust material, designed to resist tears or punctures when installing, as long as adequate care is taken. Powerbase Radon Red 300mu Gas Barrier Membrane - 25m x 4m is red in colour and includes a 3-year warranty. Powerbase Radon is a BBA Certified radon gas barrier membrane which also acts as a DPM and installed under foundation slabs for preventing the ingress of harmful Radon gas. Powerbase is a range of geosynthetic barrier membranes for protection against naturally occurring hazardous gases and soils contaminated with hydrocarbons or toxic industrial pollutants. They are also used for groundwater and environmental protection installations. Gas barriers are necessary wherever there is a risk of naturally occurring radon or methane gas. Radon is commonly found over granite formations, whereas methane and CO2 is produced as a result of the decomposition of organic matter such as made ground or natural deposits of coal, peat or silt. Developments on brownfield sites require effective gas barriers to prevent harmful gases, hydrocarbons and volatile organic compounds (VO Cs) from permeating into buildings. Typically, an impermeable barrier is designed in the foundations of the building over a ventilation layer. Hazardous gases and VO Cs migrate up through the soil and collect under the membrane in a sump from where they are vented and safely dispersed into the atmosphere. The principal function of the gas barrier membrane is to prevent harmful gases from entering the building through cracks, construction joints and service openings in the floor slab. The membrane should cover the whole plan area of the structure to all external faces in order to seal both the ground slab as well as any cavity walls and voids in hollow concrete block work. Special consideration should be given to sites contaminated by Hydrocarbons or VO Cs. These are very mobile compounds and will migrate relatively easily through unsuitable membrane materials. Aluminium laminates are superb gas barriers but these materials will delaminate when exposed to hydrocarbon vapour/VO Cs; further the aluminium layer is susceptible to oxidation due to moisture penetrating into exposed edges. A comprehensive range of task-specific engineered barriers and accompanying accessories provide consultants and design engineers effective barrier solutions and for the contractor a rapid, simple and cost-effective installation.
