Gas Barrier Membranes & Type A Waterproofing Solutions
Clever Shield supplies a professional range of gas barrier membranes and related Type A (barrier) waterproofing solutions designed to protect buildings from harmful ground gases and moisture. These systems are commonly specified on brownfield or contaminated sites and in areas where gases such as radon, methane, and carbon dioxide may be present.
Our membranes support safe, compliant construction by helping control gas migration and protect the building envelope. For project guidance, our technical team can help you select the correct membrane, tape, and detailing accessories.
Why Gas Barrier Membranes Matter
- Ground gas protection – Helps reduce gas ingress risk from radon, methane and carbon dioxide
- Site suitability – Commonly used for brownfield and contaminated land development
- Durability – Designed for long-term performance under slabs and within foundation build-ups
- System compatibility – Works with sealing tapes and detailing components for continuity
Gas Protection Systems We Supply
-
Gas Barrier Membranes
High-performance membranes designed to resist gas migration through ground-bearing floors and sub-structures. -
Gas-Resistant Tapes & Detailing Accessories
Jointing tapes, top hats and accessories to maintain continuity at laps, corners and service penetrations. -
Combined Gas & Damp Protection Options
Selected membranes provide dual-purpose protection within floor and foundation build-ups.
Type A Waterproofing (Barrier Protection)
BS 8102 defines Type A waterproofing as barrier protection applied to internal or external surfaces to resist water pressure and ingress. Type A systems are widely used for below-ground waterproofing and are often referred to as tanking.
- External and internal barrier systems for basements and retaining walls
- Sheet and liquid membranes depending on substrate and detailing requirements
- Continuity detailing to help link into DPC and adjacent waterproofing measures

Quick FAQs
What gases do gas barrier membranes protect against?
Gas barrier membranes are typically specified to help reduce the risk of gas ingress from ground gases such as radon, methane and carbon dioxide. The correct membrane should be selected based on the site risk assessment and specification.
Do gas barrier membranes need special tapes and detailing?
Yes. Maintaining continuity at laps, corners and service penetrations is essential. Use compatible jointing tapes and detailing accessories to support a compliant installation.
Are gas membranes the same as damp proof membranes (DPM)?
Not always. Some membranes provide dual protection, but gas protection requirements are site-specific. Always follow the project design and ensure the membrane is suitable for the required gas resistance and build-up.
Can you help select the right system?
Yes. Call 01268 472358 for guidance on membrane selection, tapes, detailing and compatibility with Type A waterproofing systems.
