Engineered as a premium-grade membrane for outstanding field performance in a wide range of application scenarios, the Bitumen Self-Adhesive Waterproof Membrane is composed of a high-strength co-extruded protective layer, advanced modified bitumen compound, and a backing release liner that safeguards the adhesive properties. When installing, the release liner can be easily removed, allowing the modified bitumen to securely adhere to substrates made from different materials.
- Ideal for waterproofing underground structures and both concrete and timber roofing surfaces in commercial and residential buildings.
- It is also well-suited for waterproofing and damp-proofing other building elements that demand materials with excellent tensile and tear resistance, as well as high stretchability.
- Outstanding physical properties: remarkable tensile strength, adaptable sealing at nail penetrations and fissures, and broad compatibility with diverse substrates.
- Cold-applicable design: eliminates fire hazards; the self-bonding asphalt ensures robust adhesion and seamless overlapping.
- Premium cross-laminated surface film: provides dimensional integrity, superior tear resilience, and enhanced protection against punctures and impacts.
- Versatile use in intricate areas, integrates well with other waterproofing solutions.
- Hassle-free repair process: strong substrate adhesion restricts water spread even when leaks occur, allowing for swift damage identification and immediate restoration.
