Visqueen gas protection systems have been supplied by SIG Construction Accessories to an accommodation facility for Hinckley Point construction workers and their families in order to protect against ground gases.
Working with contractors Laing O’Rourke, a comprehensive gas protection membrane system was installed at the development in Bridgwater, Somerset which supports the construction of the new Hinkley Point C nuclear power station.
The site for the development was classified as a ‘moderate risk’ Characteristic Situation Level 3 for ground gas, under the gas membrane code of practice BS8485:2015, as it had high concentrations of methane and CO2 present. The very high insulation and efficiency standards for the buildings made it critical to install an effective gas protection system in order to meet the standards outlined in the BS8485 “Design of Protective Measurements for Methane and Carbon Dioxide Ground Gases for New Buildings” guide to ensure residents were protected.
Visqueen’s Gas Barrier was specified, as it protects buildings against both methane and carbon dioxide gases.
SIG Construction Accessories became involved in the project when Visqueen and Laing O’Rourke approached the Bristol branch to supply the materials to the site. Visqueen’s Gas Vent Mat, Bollards and other additional materials are also being used within the system which contractors Laing O’Rourke are installing along with the Gas Barrier membrane. To ensure the correct standard of installation operatives received training at Visqueen’s new Training Academy in Heanor.
