BITUTHENE® 8000/8000 HC

Advanced, self-adhesive, solar reflective, water, moisture and gas proofing membrane for above and below ground waterproofing applications

Product Description

BITUTHENE® 8000 / 8000 HC Waterproofing Membrane combines the proven BITUTHENE® adhesive technology with a unique, grey-coloured carrier film to provide superior performance and easier installation. BITUTHENE® 8000 / 8000 HC Waterproofing Membrane 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 50mm minimum lap. BITUTHENE® 8000 / 8000 HC Waterproofing Membrane 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 / 8000 HC Waterproofing Membrane.

Product Advantages

  • Water and moisture proof — Provides protection for Grades 2, 3 and 4, BS 8102:1990.  Basement Grades 1, 2 and 3 as per BS 8102:2009 and IS 16471:2017.

  • Gas-resistant — Protects against methane and radon.

  • Non-metalised film — Not vulnerable to chemical attack; eliminates overbanding of laps associated with aluminum-based membranes.

  • Cold applied — Self-adhesive overlaps ensure continuity.

  • Wide application “window” reduces delays — Application temperature ranges from -5ºC to +35ºC (Hot Climate grade is up to 55ºC) and damp surface tolerant.

  • Solar reflective surface — Over 20% reduction of solar heat absorption while membrane is temporarily exposed.

  • Facilitates quality assured installation — Printed overlap line ensures minimum laps; light colour highlights accidental damage for simple patch repairs.

  • Dimension stability — Wrinkle-resistant.

  • Chemical resistance — Provides effective external protection against aggressive environment.

  • System compatibility — Can be combined with PREPRUFE®  pre-applied membranes, BITUTHENE®  Liquid Membrane, and HYDRODUCT®  drainage composites for system solutions.

Applications

It can be used horizontally or vertically to protect basements and other critical sub-structures from the effects of water, damp and gas penetration Also, BITUTHENE® 8000 / 8000 HC Waterproofing Membrane is suitable for flat decks such as inverted roofs, elevated or grade level podiums or plaza decks as the reduced solar gain is an advantage.

Ancillary Products

Primer

Primer B2 / WP-3000 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® Liquid Membrane

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 and backfill is prevented by BITUTHENE® Protection Boards.

Installation

At air temperatures below +4ºC 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 / WP-3000 applied at a rate of 8m² (12-15m² for WP-3000) per litre. BITUTHENE® 8000 / 8000 HC Waterproofing Membrane shall be laid by peeling back the protective release

BITUTHENE® Liquid Membrane to be applied at all internal and external corners, penetrations, etc., prior to applying the overall membrane. BITUTHENE® 8000 /8000 HC Waterproofing Membrane 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.
