Baseline 8 is a cavity drain membrane for tanking walls, floors and vaulted ceilings subject to high groundwater levels and persistent moisture.­  This basement water­pro­ofing membrane is moulded from high density polyethylene (HDPE) and incorporates integral 8mm stand-off studs at 25 mm centres. These water­pro­ofing products are supplied in a choice of 40m2 and 48m2 rolls, each including an 80mm wide stud-free strip for overlapping sheets.

As a BS 8102: 2009 Type C compliant water­pro­ofing membrane, Baseline 8 is suitable for use on masonry or concrete substrates and can be used in new construction or in existing buildings as part of a tanking system that delivers a Grade 3 dry environment in basements and cellars.

When used on walls, studs can be screwed to the membrane fixing plugs to secure a frame for dry-wall lining with plaster­board; when used on floors the impermeable surface permits direct laying of floors and concrete screeds.

To waterproof wall surfaces, Baseline 8 cavity drain tanking membrane typically requires:

  • 1 roll of water­pro­ofing tape or 4 rolls of butyl rubber rope
  • 200 brick plugs with ready-mounted waterproof seals

For water­pro­ofing floors, 1 roll of Baseline 8 waterproof membrane typically require:

  • 1 roll of water­pro­ofing tape
  • 1 roll of corner tape for use at floor/wall abutments

Baseline 8 water­pro­ofing membrane forms part of a sealed basement tanking system with cavity drainage for disposing of water accumulation in situations where water ingress is an issue.
