Gas-resistant membranes offer an extra level of protection to structures and buildings against potentially harmful ground gases, with common examples being CO2, radon, methane, hydrocarbons, and volatile organic compounds, or VOCs.
Our specialist contractors are highly skilled in the installation of ground gas membranes using numerous jointing methods, including both welding and tape systems depending on the nature of the project. Where applicable, the incorporation of ventilation measures will be discussed to ensure that the gas membrane system delivers maximum performance and maintains a safe living environment.
In the vast majority of instances, an independent inspection and verification of the installation will be required, in accordance with Ciria document C735. This can follow multiple methods, which often involves a combination of visual inspection, integrity testing via an air lance, and non-destructive mechanical testing of seam joints. In some cases, a gas tracer or a similar testing system will also be employed.
