GROUND GAS PROTECTION SYSTEMS


Gas protection is a technical solution to prevent or to control
gas penetration into properties and structures. Gas protection
systems are critical in projects constructed on land affected by
permanent ground gas and/or volatile organic compound (VOC)
contamination.


Greater emphasis on appropriate gas protection measures have
been brought about by the issue of BS 8485: 2015 – Code of
Practice for the Design of Protective Measures for Methane
and Carbon Dioxide Gases for New Buildings. All ground gas
(Methane, Carbon Dioxide, Radon, VOC’s, along with others)
protection systems should be designed in accordance with the
most up to date Guidance and Regulations. Attention is drawn
to CIRIA C665, C716, C735, C748 and BS 8485:2015. In addition,
there are specific requirements for building warranty providers
such as NHBC.
