Vexcolt were on hand to provided their Isolatec CVIM product which is a Contact Voltage Isolation and Waterproof Membrane (CVIM) formulated to prevent the transfer of static electrical current through concrete slabs and walls in dry and wet conditions. Comprising a butyl rubber membrane, it has a self-adhesive base layer for bonding the membrane to differing substrates such as concrete slabs and metalwork. To ensure extra safety, this membrane was also used on the Vexcolt Micratec VL movement control joint, which was provided through out the station, which complies with the LUL Fire Safety Standard 1-085. The Megatec 300 was also installed across the station for larger expansion gaps.
