VISQUEEN V20 MEMBRANE 2x20m x 20mm

Uses:
◇ Type C waterproofing is defined in BS 8102: 2022 as ‘drained protection’. This is achieved by the incorporation of a drained cavity within the basement structure. The basement walls and floor must provide enough primary resistance to water ingress to ensure the cavity only accepts a controlled amount of water or dampness. Water is collected in the cavity, between the external wall/floor and an internal lining (cavity drain membrane), and diverted to a suitable drainage point.
◇ The membrane can be used as an internally applied horizontal or vertical membrane as part of a Visqueen Cavity Drain System. The system is typically used for internally tanking basements, sub structures and retaining walls within new, existing and retrofit build projects. The system can also be used for heritage buildings, conservation projects, vaulted ceiling, basements and tunnels.
◇ When used as part of a Visqueen cavity drain system, Visqueen V20 Floor Membrane is suitable for structures requiring Grades 1, 2 or 3 waterproofing protection.
◇ The cavity drain system can also be used in conjunction with Visqueen Type A or Type B waterproofing protection systems where combined protection is required.
