Bituthene® 8000

Advanced, self-adhesive, water, moisture and gas proofing membrane for sub-structures

Product Description

Bituthene® 8000 combines the proven Bituthene adhesive technology with a unique, grey-coloured carrier film to provide superior performance and easier installation. It can be used horizontally or vertically to protect basements and other critical sub-structures from the effects of water, damp and gas penetration.

Bituthene 8000 has been tested to withstand more than 70m head of water and is over 90 times more methane resistant than the BRE minimum recommendation.

The membrane is printed with the Bituthene logo to aid identification plus an overlap line at each edge to ensure the 50 mm minimum laps. Bituthene 8000 is extremely tough but any accidental damage which would otherwise be missed, is made visible by the black compound showing through the light grey film. This can be simply repaired with a patch of Bituthene 8000.

Product Advantages

  • Water and moisture proof — provides protection for Grades 2, 3 and 4 BS 8102:1990.

  • Gas resistant — protects against methane and radon.

  • Superior performance — 70m hydrostatic pressure resistance with ultra low moisture transmission rate.

  • Non-metallised film — not vulnerable to chemical attack; eliminates overbanding of laps associated with aluminium based membranes.

  • Wide application “window” reduces delays — application temperature range from -10ºC to +35ºC and damp surface tolerant.

  • Easier handling in warm weather — over 20% reduction of solar heat absorption.

  • Unique composite film — engineered for strength, flexibility and a smooth finish.

  • Facilitates Quality Assured installation — printed overlap line ensures minimum laps; light colour highlights accidental damage for simple patch repairs.

  • System Compatibility — can be combined with Preprufe® pre-applied membranes, Bituthene® Liquid Membrane, and Hydroduct® for system solutions.

Damaged areas to be repaired by patching with an oversized patch applied to a clean, dry surface extending 100mm beyond damage and firmly rolled.


Bituthene 8000 preformed membrane with Bituthene LM at corners shall be laid onto smooth concrete blinding and/or vertical concrete walls by applying the preformed membrane, sticky side downwards to give well rolled 50mm overlaps. Vertical or inclined surfaces and suspended slabs to be primed with Primer B2 applied by roller or brush to achieve an even cover of the surface. Allow to dry before applying the membrane.

Primer B2

Primer B2 is used to prepare vertical and sloping surfaces and suspended slabs. It is moisture tolerant and can be used on “green” concrete or damp to touch substrates.

Bituthene LM

Waterproof continuity at angles and at penetrations is provided by Liquid Membrane, chemically curing, liquid-applied detailing compound.

Bituthene Protection Board

Damage from following trades is prevented by laying Servipak non-compressive rot proof boards spot bonded with Pak Adhesive or Bitustik™. Vertical faces are protected against backfilling by using Servipak, Hydroduct or other boards recommended by GCP, bonded with Bitustik double sided tapes.


At air temperatures below +4°C measures should be taken to ensure that all surfaces are free from ice or frost. All surfaces except those below ground bearing slabs should be primed with one coat of Primer B2 applied at a rate of 8m2 / litre. Bituthene 8000 shall be laid by peeling back the protective release paper and applying the adhesive face onto the prepared surface, free from ice, frost or condensation. Bituthene LM to be applied at all internal and external corners, penetrations etc. prior to applying the overall membrane. Bituthene 8000 should be brushed onto the surface to ensure good initial bond and exclude air. Adjacent rolls are aligned using printed lines and overlapped 50mm minimum at side and ends and well rolled with a firm pressure, using a Lap Roller to ensure complete adhesion and continuity between the layers. On high walls it may be necessary to batten fix the membrane to prevent slippage.
