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.
