Multiwraps have been extensively used by the London Underground and abroad during refurbishment of existing bitumen and cloth joints located on the tunnel walls.
A lightweight glass fibre cloth is laminated to a .5mm thick graphite intumescent membrane. The glass fibre cloth gives the Multiwrap tensile strength allowing the intumescent membrane expand around the joint to stifle the affect of heat in a fire. Multiwraps are a much cleaner and quicker method of repairing damaged or low voltage joints that are at the end of their lifespan.
