Gas Protection Membranes

Gas protection membranes are crucial when planning construction projects, especially on high-risk or contaminated sites. The JUTA range of gas membranes are high-performance, multi-functional membranes that protect structures and people from gas contamination. Our advanced manufacturing technology produces the best performing membranes on the market - explore our collection and find the right gas membrane for your project.

Gas Protection Membranes

The Complete Gas Protection Solution

Some building sites are affected by harmful, permanent ground gases or volatile organic compounds (VOCs). If buildings don’t get the necessary protection – these gases and compounds could seep into the building and damage the health of the residents.

JUTA gas membrane systems protect homes from these gases and follow legislation methodologies provided by BSI. Because gases pass through structures at different speeds, our membranes ‘select’ which gases pass through and which ones don’t, maintaining a controlled flow. Every membrane has different qualities, which is why we categorise them

Our systems also perform the function of a damp proof membrane – which prevents the uptake of moisture into the building.

Ground Gas Standards 

There are many different standards and guidance documents that detail how to understand the risk of ground contamination, and design solutions to mitigate these risks. The different documents relate to different ground contamination. Below are some of the key documents to be aware of and refer to:

BS 8485:2015+A1:2019 – Codes of practice for the design of protective measures for methane and carbon dioxide ground gases for new buildings.

  • Ground gases typically found near landfill sites, but can occur from other sources
  • Encourages the use of qualified installers
  • Validation to Ciria C735 is a requirement
  • Additional influences on the system should be considered, such as the hydrostatic conditions, and the likelihood of the source contaminant being in direct contact with the protective measures proposed

BRE 211:2015 – Guidance on protective measures for new buildings. (RADON)

  • Naturally occurring ground gas. Larger concentrations in the South-West of UK
  • Minimum recommendation is a membrane of 300 micrometre (1200 gauge) polyethylene sheet or equivalent
  • It must be installed with considerable care and protected once installed
  • Taped laps are required

CIRIA C748:2014 – Guidance on the use of plastic membranes as VOC vapour barriers

CIRIA C682:2009 – VOC Handbook

  • Risk based approach
  • No quantifiable limits on material performance
  • Testing to ISO 15105-2 and EN 14414/EN 14415
  • 9 main VOC types are tested for
  • Welded laps are required as most tapes are made from bitumen/butyl and are affected by VOCs

CIRIA C735:2014 – Good practice on testing and verification of protection systems to buildings from hazardous gases

  • Good practice on testing and verification of protection systems to buildings from hazardous gases
  • Check design and detailing is in accordance with site requirements
  • Checks the competency of the installer (NVQ LEVEL 2 minimum)
  • Test integrity of the membrane/barrier system
  • Visual inspection
  • Written report on inspection/testing and sign-off

BS8102:2009 – Code of practice for protection of below ground structures against water from the ground
