Product Description

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

Features

  • High electrical volume resistance, volume resistivity, dielectric strength and breakdown voltage characteristics

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

  • Cold applied — no hot works, 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 a 1.6mm membrane composed of 1.4mm of rubberised bitumen compound and a 0.2mm, 4 ply, cross-laminated polyethylene surface film, providing superior puncture and damage resistance. It is important to ensure that the membrane is not abused and damaged during installation or subsequent construction activities, to provide a continuous barrier to the passage of electrical current. The self-adhesive compound allows easy and safe cold application over large areas, without the need for torching or hot mopping of bituminous compounds. This is particularly important when work is being carried out in confined spaces or on underground projects such as Mass Transit Rail Station Platforms.
BITUTHENE 6000 EIM is installed to prepared concrete substrates as a double layer membrane (installed in two layers with staggered laps), providing robust protection with long design life and electrical volume resistivity of >4.8 x 1014 ohm-cm required by demanding civil projects.  
The thickness of the installed double layer membrane is 3.2mm.

Installation

Concrete and other masonry surfaces shall be dry (less than 10.0% moisture content), free of loose debris, sharp protrusions, honeycombing and bug holes. Concrete and masonry must be primed with a BITUTHENE Primer. For enclosed underground areas, for safety reasons water based BITUTHENE Primer Type C should be used, at a rate of 5 to 6 m2/litre. Porous substrates may require more than one coat of primer. Allow the primer to dry tack free before application of the membrane.
For complete instructions on the application of BITUTHENE 6000 EIM membrane, please refer to our Work Method Statement available from your local GCP representative.
