Understanding BITUTHENE® 4000
What is BITUTHENE® 4000?
BITUTHENE® 4000 is a flexible, preformed waterproof membrane that combines a high-performance, cross-laminated HDPE carrier film with a self-adhesive rubberized asphalt compound. This unique composition allows the membrane to conform to various surfaces while providing superior waterproofing capabilities.
Key Benefits of BITUTHENE® 4000
- High Adhesion: The self-adhesive nature allows for easy application, ensuring strong bonding even on challenging surfaces.
- Moisture Tolerance: Designed to be applied on damp or “green” concrete, BITUTHENE® 4000 ensures that construction can proceed without delays.
- Durability: The cross-laminated HDPE film provides robust protection against punctures, tears, and other forms of mechanical damage.
Applications of BITUTHENE® 4000
Below-Grade Waterproofing
One of the primary applications of BITUTHENE® 4000 is below-grade waterproofing. It is ideal for foundation walls, basements, and tunnels, where moisture intrusion can lead to structural damage. By creating a watertight barrier, BITUTHENE® 4000 helps prevent water seepage and mold growth.
Above-Grade Applications
In addition to below-grade use, BITUTHENE® 4000 can be applied to above-grade surfaces, such as balconies and roofs. Its flexibility and adhesion properties ensure effective waterproofing in areas exposed to the elements.
Detailing and Repairs
BITUTHENE® LM, a complementary product, is used in detailing and repairs. This liquid-applied membrane is perfect for corners, penetrations, and other intricate areas where standard membranes may not perform optimally.
Installation Guidelines for BITUTHENE® 4000
Surface Preparation
Proper installation begins with surface preparation. All surfaces must be clean, dry, and free from contaminants. For effective adhesion, it is recommended to use BITUTHENE® Primer S2 on vertical and sloping surfaces.
Application Process
- Priming: Apply the primer using a brush or roller, ensuring complete coverage.
- Membrane Placement: Peel back the protective release paper and carefully lay the BITUTHENE® 4000 membrane onto the prepared surface.
- Rolling: Use a roller to ensure full adhesion and eliminate air pockets, especially at overlaps (minimum of 50 mm).
- Protection: Immediately cover the applied membrane with protection boards to prevent damage from backfill or subsequent trades.
Special Considerations
- Ensure temperatures are above +5°C during application to avoid adhesion issues.
- On green concrete or damp surfaces, cover the membrane immediately to maintain waterproof continuity.
