Overview of BITUTHENE® Membranes
BITUTHENE® membranes are engineered for durability and performance. They feature a combination of high-density polyethylene (HDPE) and rubberized asphalt, allowing them to adapt to varying conditions while providing a robust barrier against moisture.
BITUTHENE® 3000
Designed specifically for subterranean applications, BITUTHENE® 3000 is a self-adhesive membrane that excels in creating a waterproof seal for basements and tunnels. The membrane adheres well to cured concrete surfaces, making it ideal for below-grade installations. It can be applied in temperatures ranging from 5°C to 35°C, ensuring a reliable bond under various conditions.
BITUTHENE® 4000
The BITUTHENE® 4000 membrane is well-known for its flexibility and strength. It combines a high-performance cross-laminated HDPE carrier film with a super sticky rubber bitumen compound. This makes it a preferred choice for foundation walls and parking decks. With an operating temperature range above 5°C, it is suitable for a wide range of climates.
BITUTHENE® 5000
BITUTHENE® 5000 is designed for heavy-duty applications, incorporating a high-strength mesh embedded in self-adhesive rubberized asphalt. This mesh enhances its durability, making it suitable for projects that demand extra strength, such as commercial buildings or infrastructure projects.
BITUTHENE® 8000
BITUTHENE® 8000 membranes are engineered for complex applications, including elevated decks and inverted roofs. The unique grey carrier film not only provides superior performance but also simplifies installation. Its high-performance adhesive ensures that it bonds effectively, making it a reliable choice for challenging projects.
Applications of BITUTHENE® Membranes
The versatility of BITUTHENE® membranes allows them to be used across various construction and infrastructure projects. Below are some of the most common applications:
Foundation Waterproofing
BITUTHENE® membranes are extensively used for waterproofing foundation walls in both residential and commercial buildings. They prevent water ingress, protecting the structural integrity of the building.
Tunnel and Metro Stations
In underground construction, such as tunnels and metro stations, BITUTHENE® membranes provide a waterproof barrier that protects against hydrostatic pressure and moisture infiltration.
Elevated Decks and Green Roofs
BITUTHENE® membranes are ideal for elevated decks and green roofs, ensuring that water does not compromise the underlying structure. Their ability to withstand varying temperatures makes them suitable for outdoor applications.
Infrastructure Protection
BITUTHENE® is also used in various infrastructure projects, including bridges and parking decks. Its robust design ensures long-lasting protection against water damage, which is crucial for the longevity of these structures.

Installation Guidelines
Proper installation of BITUTHENE® membranes is essential for optimal performance. Here are key guidelines to follow:
-
Surface Preparation: Ensure that all surfaces are clean, dry, and free from contaminants that could affect adhesion. For optimal results, prime surfaces with the appropriate BITUTHENE® primer.
-
Temperature Considerations: Install membranes at temperatures above the recommended range to ensure proper adhesion. Avoid installation in extreme cold conditions unless the surfaces are adequately prepared.
-
Application Method: Peel back the protective release paper and press the membrane onto the prepared surface, ensuring good initial contact. Use a roller to ensure complete adhesion and eliminate air pockets.
-
Sealing Joints: Overlap adjacent rolls by at least 50 mm at the seams and roll firmly to ensure a watertight seal. Use BITUTHENE® LM for sealing internal and external corners.
-
Protection: Once installed, cover the membrane with a protective layer as soon as possible to prevent damage during construction.
