Voidformers / vent layers for gas protection ventilation
PAGeoTechnical has developed an extensive range of gas protection ventilation products that include voidformers and vent components. When installed as part of a designed gas venting system, they will safely disperse harmful gases to atmosphere.
Under BS8485:2015 it is recommended that all gas protection designs should include provision for some form of sub-floor ventilation. Depending on the site risk this may be a simple pressure relief pathway or demonstrable ventilation with good or very good performance.
PAG offer advice and design appropriate for the gas risk identified including demonstration by calculation for ventilation design performance. All part of our ground gas solutions.

Ground gas protection ventilation components
PAGeoTechnical has developed an extensive range of ventilation components that when installed as part of a designed gas venting system will safely disperse harmful gases to atmosphere. All PAG passive gas venting components are supplied with venting calculations to prove their efficiency in line with BS 8485.
The range includes T pipes, bends and couplings, slotted pipes, voidformer outlets, air bricks, periscope vents and many more.
