Specification

NBS Specification J40 (Clause 290) Flexible Sheet Tanking/Damp Proofing.  BS 8102:2009 Type C Drained Protection.

Available in 3 stud heights: 8mm, 7mm and 4mm.

Depending on the application required and the site conditions, the membrane may be used as:

  • a dry lining for walls, ventilated into the room via aeration slots at the top and bottom of the wall or via passive air vents, where access through an external wall is available
  • a sealed system covering wall, floor and ceiling with provision made for disposing of water build-up behind the membrane via a sump and pump.

It can support plastering, rendering or a dry lining fixed by plaster dabs (where appropriate) in the following situations:

  • on damp walls in underground situations subject to high groundwater levels, and perennial moisture
  • on vaulted ceilings of archways or cellars subject to water ingress
  • in conjunction with a remedial dpc system where the walls have a high salt content, and/or it is necessary to complete the installation immediately without allowing a period for initial drying
  • over walls which have a friable or painted surface, are contaminated with oil or mould, or have a high salt content
  • as a waterproofing membrane in areas subject to vibration.
