Advanced, self-adhesive, solar reflective, unique HDPE composite film Waterproofing membrane for waterproofing and protection of concrete in basements, foundations and above ground waterproofing applications.

Product Description

GCP Applied Technologies (“GCP”) BITUTHENE® 8000 HC Waterproofing Membrane combines the proven BITUTHENE® adhesive technology with a unique, full width grey-colored solar reflective film to reduce solar gain and facilitate easier installation and damage detection. BITUTHENE® 8000 HC Waterproofing Membrane has been tested to withstand more than 70m head of water.

Product Advantages

  • Membrane is printed with overlap lines and BITUTHENE® trademark to facilitate lap alignment and help prevent specified product substitution 
  • Tough light Grey reflective carrier film and black waterproofing compound contrast to allow for easy identification of any accidental surface damage and facilitate identifying areas needing repair
  • PROPRIETARY ADHESIVE: Advanced self-adhesive formulation unique to GCP
    – Allows immediate repositioning, improving the quality and speed of installation
    – Durable intimate bond that prevents water migration
  • Hydrostatic head resistance tested at laps crossing a crack >70 m
  • Resistant to aggressive ground conditions
  • Grey, solar reflective surface – reduces solar gain and allows up to 30 days exposure before backfilling.
  • Water and moisture proof — Provides protection for Grades 1, 2, and 3 as per BS 8102:2009 and IS 16471:2017.
  • Chemically Resistant - External protection against most aggressive soils and ground water conditions
  • Cold applied — Self-adhesive overlaps designed to ensure continuity. No special equipment needed for application. 
  • Wide application “window” reduces delays — BITUTHENE® 8000HC (Hot Climate grade) application temperature upto +55ºC 
  • Facilitates quality assured installation — Printed overlap line ensures minimum laps; light colour highlights accidental damage for simple patch repairs.
  • Dimensional stability of the composite HDPE film aids in  wrinkle-resistance. 
    •    Full width edge to edge film for highest waterproofing integrity 
    •    Twin seal system: best resistance to water and continuity of protection. Edge bead allows adhesive to adhesive sealing and Adhesive to film sealing is achieved due to full width of the film.
  • System compatibility — Can be combined with PREPRUFE® pre-applied membranes, BITUTHENE®.
  • Liquid Membrane, and  HYDRODUCT® drainage composites for single source system solutions.
  • Since 1997, BITUTHENE® 8000HC product application and suitability has been certified by BBA for water tightness and durability

It is critical to protect in place BITUTHENE® 8000 HC membranes from damage due to following trades and backfill. SERVIPAK® Flex Protection Board is specifically designed to help avoid damage to the in place membrane and ease of installation.

Limitations of Use

  • Approved uses only include those uses specifically detailed in this product data sheet and other current product data sheets that can be found at BITUTHENE® 8000 HC Membranes are not intended for any other use. Contact GCP Technical Services where any other use is anticipated or intended.
  • BITUTHENE® 8000 HC Membranes are designed where in-service temperatures will not exceed 131  °F (+49°C). 
  • BITUTHENE® 8000 HC Membranes are not designed for permanent above ground exterior exposure. Exposed areas at upstands etc. should be covered with A GCP recommended suitable flashing material. 
  • Do not use BITUTHENE® Mastic to terminate BITUTHENE® Membranes to PREPRUFE® pre-applied waterproofing membrane systems. Terminations to PREPRUFE® membranes should only be done with BITUTHENE® LM
  • Do not apply BITUTHENE® Membranes over insulation or lightweight insulating concrete. Contact GCP for further clarification. 

Safety and Handling Information

Users must read and understand the product label and safety data sheet (SDS) for each system component. All users should acquaint themselves with this information prior to working with the products and follow the precautionary statements. SDSs can be obtained by contacting your local GCP representative or office, and in some cases from our web site at


  • All products must be handled and stored consistent with BITUTHENE® 8000 HC methods statement
  • All BITUTHENE® Membranes should be stored upright
  • Observe one-year shelf life and use on a first in, first out basis.
  • Store in dry conditions below 40ºC

Technical Support, Details and Technical Letters

The most up to date detail drawings and technical letters are available at or in the applicable Method Statement. For complete application instructions, please also refer to the current GCP Applied Technologies Contractor Handbook and Literature on ( Documents in hardcopy as well as information found on websites other than may be out of date or in error. Before using this product, it is important that information be confirmed by accessing and reviewing the most recent product information, including without limitation product data sheets and contractor manuals, technical bulletins, detail drawings and detailing recommendations. Please review all materials prior to installation of BITUTHENE® 8000 HC Membrane. For technical assistance with detailing and problem solving please contact your local GCP representative or office.

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 must be primed with the appropriate BITUTHENE® 8000 HC primer as detailed in the individual primer product data sheet.  Waterproofing Membrane 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® Liquid  Membrane to be applied at all internal and external corners, penetrations, etc., prior to applying the overall membrane. BITUTHENE 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. Once the membrane is applied, cover with a protection board as soon as possible. On “green” concrete or damp surfaces, cover the membrane immediately.

Repairs, Protection & Drainage

  • Damaged areas to be repaired with an oversize patch applied to a clean dry surface extending 100 mm beyond damage and firmly rolled.
  • Protect BITUTHENE® membranes immediately after application to avoid damage from other trades, construction materials or backfill, using Protection 03 boards.
  • If the area around the substructure can be drained to a low level outlet then GCP recommends the use of HYDRODUCT® drainage sheets be used as protection board and to help direct water away from the structure.
