Basement Subway tunnel Excellent high and low temperature resistance
Product Description
| Product Name | Self Adhesive Waterproof Membrane |
| Material | Bitumen |
| Color | Black,silvery |
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.
Application
-
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.
Advantages
-
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.
