Heavy duty, preformed composite membrane combining a self-adhesive rubber/bitumen compound and a tough, puncture-resistant four-ply polyethylene laminate for electrical insulation in critical sub-structures and civil works

Product Description

BITUTHENE® 6000 EIM, whilst designed as a waterproofing membrane for concrete structures, possesses excellent electrical insulation properties. BITUTHENE is composed of a tough, cross-laminated polyethylene film, backed by a self-adhesive rubberised asphalt compound, all of which components provide high resistance to the passage of direct or alternating current.


  • Cross-laminated film — provides dimensional stability, high tear strength and puncture resistance.

  • Cold applied — no heating, hot mopping or torches.

  • Flexible — retains flexibility to accommodate ground movement, structural movements.

  • Controlled thickness — factory controlled uniform thickness.

  • Chemically-resistant.

  • Simple, reliable, low labour cost installation.

BITUTHENE 6000 EIM is composed of 1.4mm of rubberised asphalt compound and 0.2mm, 4 ply cross-laminated polyethylene providing superior puncture and damage resistance. It is important to ensure that the membrane resists damage during installation, and during subsequent construction activities, to provide a continuous barrier to the passage of current. The self-adhesive compound allows easy and safe cold application over large areas, without the need for torching or hot mopping of asphaltic compounds. This is particularly important when work is being carried out in confined spaces or underground, on, for example Mass Transit Rail Station Platforms.

BITUTHENE 6000 EIM is installed to prepared concrete substrates either as a single layer membrane or a double layer membrane (installed in two layers with staggered laps), depending on the volume resistivity project requirement, which both options will provide robust protection with long design life and electrical volume resistivity. 


Concrete surfaces shall be dry, free of loose debris and sharp protrusions and hollows. An application of WP-3000 water-based primer is recommended, at the rate of 12 to 15m2 / litre. A water-based primer is recommended, for safety reasons, when working in enclosed spaces underground. The primer is allowed to dry completely before application of the membrane.

For complete instructions on the application of BITUTHENE membranes, please refer to our general data sheets and contractor guide, available from your local GCP representative.
