Installing Gasproof Membranes: Ensuring Protection and Mitigation
Gasproof membranes play a crucial role in safeguarding structures against harmful gases such as radon and volatile organic compounds (VOCs). With adherence to standards such as BS8102:2022 for waterproofing and BS8485 for gas protection, Cannon Clarke offers expertise in designing and deploying installations that provide robust defence against these hazards.
Understanding Gasproof Membranes:
Gasproof membranes are specialised barriers designed to prevent the ingress of gases, including radon and VOCs, into buildings. Radon, a radioactive gas derived from the decay of uranium in soil and rock, can accumulate indoors and pose serious health risks, including an increased risk of lung cancer. VOCs are organic chemicals that can vaporise and release into the air, potentially causing adverse health effects such as respiratory irritation and exacerbation of existing conditions.
The Role of Standards:
Adhering to standards such as BS8102:2022 and BS8485 is essential for ensuring the effectiveness and durability of gasproof membrane installations. BS8102:2022 provides guidance on waterproofing below-ground structures, including recommendations for the selection and installation of membranes to protect against water ingress. BS8485 specifically addresses the protection of buildings from hazardous ground gases, outlining measures to mitigate risks associated with radon and VOCs.
How Cannon Clarke Can Help?
Cannon Clarke offers comprehensive solutions for designing and deploying gasproof membranes tailored to the unique requirements of each project. Our team of experts utilises industry-leading techniques and materials to deliver effective protection against radon and VOCs.
Services Offered:
Site Assessment: We conduct thorough assessments to identify potential risks and determine the most appropriate membrane system for the site, considering factors such as soil composition, groundwater levels, and building design.
Design and Specification: Our experienced engineers develop detailed designs and specifications in accordance with BS8102:2022 and BS8485, ensuring compliance with regulatory requirements and best practices in gas protection.
Installation: With extensive experience in membrane installation, our skilled technicians ensure precise and efficient deployment, utilising advanced techniques to achieve a seamless and durable barrier against gas ingress.
Verification of our Works: Having gasproof membrane installations checked by a third-party verification standard is of paramount importance for several reasons:
Quality Assurance: Third-party verification ensures that the installation meets established standards and regulations. This independent assessment helps to confirm that the gasproof membrane has been installed correctly and is functioning as intended.
Compliance: Many regulatory bodies and building codes require verification of gas protection measures, including gasproof membranes. Compliance with these requirements is essential to avoid potential legal issues and ensure the safety and integrity of the structure.
Risk Mitigation: Gas ingress, particularly from substances like radon and VOCs, can pose significant health and safety risks to building occupants. Third-party verification helps to mitigate these risks by providing assurance that the gasproof membrane is effectively preventing the entry of harmful gases into the building.
Long-Term Performance: Gasproof membrane installations are intended to provide long-term protection against gas ingress. Third-party verification can help to identify any potential issues or deficiencies early on, allowing for corrective action to be taken before problems escalate and ensuring the continued effectiveness of the membrane over time.
Confidence and Trust: Third-party verification instils confidence in building owners, occupants, and stakeholders that the gasproof membrane installation has been carried out to the highest standards of quality and integrity. It provides an objective assessment of the installation’s performance, fostering trust in the reliability and safety of the building.
Overall, third-party verification of gasproof membrane installations is essential for ensuring compliance, mitigating risks, and maintaining the long-term effectiveness of gas protection measures. It provides peace of mind for all involved parties and contributes to the overall safety and sustainability of the built environment.

Our Process
Survey
We start by conducting a thorough survey of the space you want inspected. There's usually a fee for our initial consultation.
01
Scoping discussion
We collaborate with you to marry your objectives with our findings from the survey. We’ll discuss how you want to use the space when it’s finished and the best way of achieving your vision.
02
Design
Once we have the physical specifications, and your input on your requirements, we’ll design a system that works for you.
03
Approval
We’ll send you a specification, together with a report which explains the technical aspects. We’re happy to chat through this with you and make any changes you’ve identified.
04
Work begins
With an approved plan in place, we’ll get to work on the date we’ve agreed between us.
