When building below ground, the requirement to protect structures against ingressing water is key. However, the potential threat from ground gases penetrating a building is just as prevalent. Furthermore, effective ground gas protection can be achieved at the same time as comprehensive waterproofing.
In the February edition of Concrete Magazine, Richard Crossley our Technical Director discusses the industry standards for gas protection and how practical safeguards can be designed into new buildings.
The article examines British Standard 8485:2015 which covers the level of risk from carbon dioxide and/or methane and then the importance of guarding against the dangerous effects of radon gas. For further information on how to deal with gas-affected sites using combined information from Public Health England and the recommendations of the British Standard it is possible to propose a practical solution.
In the article cover picture, Newton PAC 500 System, our combined ‘Type C’ (BS 8102:2009) specialist Cavity Drain Waterproofing and Ground Gas mitigation system was installed on a massive scale in the basement of this new-build mansion in Windlesham.
