Product Benefits

JUTA GP® TITAN OVERTAPE is compatible with our full range of Gas Barriers, including:

  • JUTA GP®1
  • JUTA GP®2
  • JUTA GP®H
  • JUTA GP® TITANFLEX
  • JUTA GP® TOP HATS AND PREFORMED CORNERS
Product Description

GP® TITAN OVERTAPE has excellent adhesion to all JUTA membranes, and a wide range of substrates. The GP® TITAN OVERTAPE is single sided, with release film on one side. It is specially formulated to act as a joint sealer for GP® TITANBOND® membrane to prevent concrete influx into the joint areas.

The flexible composition of the GP® TITAN OVERTAPE makes it highly conformable to irregular surfaces, and it is easy and accurate to use with little to no waste. GP® TITAN OVERTAPE has unrivalled levels of adhesion to the gas barriers and is designed to remain flexible throughout the service life.

Application temperature range is +5 to +40oC. Prior to application, all surfaces should be clean, dry and free from frost, grease and loose detritus materials. Apply direct from the reel onto the surface and press along the whole application length to achieve optimal adhesion. Remove the backing paper and offer the opposite surface to the GP® TITAN OVERTAPE and press firmly to deal the joints. JUTA recommends the use of a silicon roller for optimal pressure application to taped joints.

GP® TITAN OVERTAPE has a shelf life of approximately 24 months when store flat in original packaging in cool dry conditions.

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® TITAN OVERTAPE

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® TITAN OVERTAPE

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® TITAN OVERTAPE

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
