Gas proofing creates effective barriers that prevent harmful ground gas from entering your property. Our specialised systems protect against methane gas, carbon dioxide, radon gas, and other contaminants, ensuring safe, compliant commercial and residential environments.
Ground gases pose serious health and safety hazards when they accumulate in enclosed spaces.
Methane gas creates fire and even explosion risks, carbon dioxide can cause asphyxiation, and radon gas is a known carcinogen. These invisible threats can migrate through soil and enter buildings through cracks, joints, and porous building materials, particularly in ground structures without adequate protection.
Sites built on former industrial land, landfills, or in areas with specific geological features are especially vulnerable.
At Renlon, we’re constantly developing better solutions for our clients and the properties that we work on. Our innovation has led to the creation of proprietary products that offer significant advantages over traditional methods.
RenStrength is our revolutionary waterproofing system that eliminates the need to remove existing renders. This breakthrough technology applies directly over failed waterproofing systems, significantly reducing project timelines and disruption.
We are also excited to introduce RenTherme…
We offer multiple gas proofing technologies, including advanced liquid gas membrane applications using styrene butadiene latex-based formulations.
Our gas seal products create durable, continuous barriers that maintain structural integrity throughout the curing process.
Whether standalone or combined with damp proofing and waterproofing systems, our solutions effectively block the pathway for gas movement into your building.

Here are some common questions about gas proofing. If you need full details about your specific situation, please contact us.
Contact UsAny structure built on land with potential gas contamination may require protection. This includes former industrial sites, landfills, areas with naturally occurring radon, and locations with specific geological features that produce ground gas.
UK building regulations increasingly require gas protection measures for new builds and major renovations on affected sites.
Gas proofing and waterproofing often work together as complementary systems.
For below-ground structures like basements, this combined approach ensures comprehensive protection.
When properly installed to specifications, modern gas barrier systems should last the lifetime of the building.
The durability of our membrane systems is excellent, with high-quality materials designed to resist degradation.
