JUTAMAT 5000 is a mechanically bonded geosynthetic clay liner (GCL) composite of pulverised bentonite embedded between two layers of geotextile. Additional bentonite is added to the overlap edges for ease of sealing. JUTAMAT 5000 complies with the latest codes of practice as published in LFE 3 – using geosynthetic clay liners in landfill engineering.

Product Benefits

  • The Bentonite absorbs water from the surrounding soil to enable to be used as a containment barrier.
  • JUTAMAT offers a good sealing performance
  • JUTAMAT is cost-effective and eco-friendly
Product Description

JUTAMAT is a mechanically bonded Geosynthetic Clay Liner (GCL) composite of pulverised bentonite embedded between two layers of geotextile. The internal 5kg of natural sodium bentonite swells in contact with water to form a low permeability waterproofing barrier.

Bentonite absorbs water from the surrounding soil, its expansion is impeded by layer pressure from the geotextile membranes creating an impermeable lining material able to be used as a containment barrier.

JUTAMAT 5000 should be installed in accordance with the product installation guidelines.

  • Reservoirs & Lakes
  • Landfill Capping and Cells
  • Leachate Lagoons
  • Effluent Treatment
  • Industrial Sludge Basins
  • Bund & Tank Linings
  • Pond & Canal Linings

Roll weights can be in excess of 1000kg and hence appropriate care and equipment is required for unloading and handling.

Rolls of JUTAMAT 5000 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

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 micrometres (1200 gauge) polyethene 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 requirement
  • 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
