Product Description

GP® TITANFLEX® is a loose laid multilayer, low polyethylene membrane. GP® TITANFLEX® is specifically designed, manufactured and tested and certified to perform as a methane, carbon dioxide, radon, ground gas, VOC air & moisture and hydrocarbon protection system. GP® TITANFLEX® is used as a loose laid membrane for the gas/VOC protection of ground level structures.

Part of the GP® TITANFLEX® family of membranes, the GP® TITANFLEX® is a high performance, hydrocarbon barrier, manufactured from a unique HDPE resin. The primary membrane has excellent chemical resistance and is ideal for use on sites affected by hydrocarbon and VOC contamination. It will also effectively prevent the ingress of a number of other harmful gases, including radon, methane and carbon dioxide.

On more heavily contaminated sites, a passive or active venting system in addition to a gas barrier may be required to dilute the gases down to acceptable levels and specific design advice should be sought.

JUTA UK – radon, ground gas, vapour, air and moisture barrier characteristic properties:

  • High Chemical Resistance
  • High resistance to Ground Gasses
  • Long Term Durability (Performance guaranteed for the lifetime of the building)
  • Compatible with all building materials
  • Manufactured to meet the most up to date British Standards and guidance.

GP® TITANFLEX® should be installed in accordance with the product installation guidelines, and in accordance with best practice.

GP<sup>®</sup> TITANFLEX

A selection of standard details for information and education purposes only. Note - it is strongly advised appropriately qualified, and insured personnel undertake gas membrane installs. A gas membrane performs a critical function in the application setting and has an anticipated design service life in excess of 60 years. Do not attempt to install gas membranes from these details alone. Sole rights for use and distribution are owned by JUTA UK LTD.

Roll weights can be in excess of 20kg and hence appropriate care and equipment is required for unloading and handling.

Rolls of GP® TITANFLEX® should be stored on stable/level ground and stacked not more than five rolls high, with no other material stacked on top. The rolls can be stored outdoors when packaged, but should be protected from exposure to UV.

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
GP<sup>®</sup> TITANFLEX

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
GP<sup>®</sup> TITANFLEX

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
GP<sup>®</sup> TITANFLEX

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
