VOLTAGE ISOLATION & WATERPROOF MEMBRANE SEALING SYSTEM

Description

CORKJOINT® M-SEAL® VM500 Voltage Isolation & Waterproof Membrane Sealing System is a self-adhesive butyl rubber based Voltage Isolation and Waterproof Membrane with a geotextile top layer, for use on slab and wall applications. Made from a special bitumen-free butyl rubber composition, the M-SEAL VM500 is an easy, clean and environmentally friendly solution for preventing the transfer of static electrical currents through concrete slabs and walls, in both wet and dry areas of application.

The self-adhesive layer of M-SEAL® VM500 bonds strongly to the existing substrate, while the concrete topping screed (secondary top layer) bonds tenaciously to the geotextile layer of the membrane. This dual bonding process prevents any separation between the substrate and the concrete topping screed which also helps maintain the quality and sustainability of the finished floor coverings.

M-SEAL® VM500 has high crack-bridging capabilities and due to the tenacious bonding of the slab, and the topping layer slab, to the geotextile membrane layer on the top of M-SEAL® VM500 membrane, it becomes a fully bonded membrane system to the substrate and the proceeding concrete layer, which also enables it to isolate, insulate and prevent the transfer of electrical currents and water through the concrete or via cracks in the concrete.

Uses

• Railway station platform slabs and walls

• Viaducts and Bridges

• Power Stations and Utilities

• Electrical Riser Rooms

• Base slabs, walls and roofs for waterproofing (a topping slab must be applied)

Advantages

• Provides excellent electrical insulation in both wet and dry conditions

• A self-adhesive membrane with excellent adhesion to the concrete substrate, for both floor and wall applications. Use CJ-200-15 Adhesive Primer (water-based). No torch-on or hot-iron requirements needed for installation, so no harsh or hazardous fumes are created

• Bonds to most types of surfaces (concrete, steel, ceramic, PVC pipe) with the use of CJ-200-15

• Adhesive Primer

• Fast and easy to install compared to conventional membrane systems

• A geotextile top layer for high performance bonding to concrete topping slabs and to screed coatings of various thicknesses. Also prevents the migration of water between membrane and finishes

• Can withstand up to 5.73 x 10^14 ohm-cm at a thickness of 2.5mm

• High crack bridging capabilities of up to 2mm

• Produced from a special SBS Modified rubber composition with both the adhesive bottom layer and the geotextile top layer bonded during the manufacturing process

• No bentonite present so the product does not expand and break-up in water and/or wash from the joint, removing the potential of voids between slab/wall and finishes. SBS Modified rubber gives long-term durability and integrity to the product and in-turn to the joint and substrate
