Self-Adhesive Butyl Waterproofing Ultimate Grip Tear Resistance Simplified
Product Description
| Roduct Name | Aluminum Foil Butyl Rubber Waterproofing Membrane |
| Material | Butyl |
| Color | Silver |
Engineered with a butyl rubber compound and backed with reinforced aluminum foil, this self-adhesive membrane (single/double-sided) forms a powerful bond with diverse materials, perfect for color steel tiles and roof cracks. It delivers long-lasting performance with excellent weather, aging, and waterproofing properties, creating a durable seal. Its key feature is a lifelong non-curing nature that ensures it adapts to substrate movement and provides ongoing shock absorption. Being 100% solvent-free, it installs without shrinkage, toxic fumes, or environmental concerns.
Product Characteristics
• Active Creep Technology: Bonds with and deeply penetrates concrete, automatically sealing potential leak paths caused by cracking.
• Robust Mechanical Performance: Offers powerful adhesion, high tensile strength, and superior flexibility to handle structural movements.
• Enduring Performance: Maintains integrity against harsh chemicals, extreme weather, and UV radiation for over two decades.
• Low-Temperature & Green Installation: A safe, VOC-free material that enables fast, cold-adhesive application from -5°C, ensuring environmental and user safety.

| Tearing strength/ N | ≥20 | With Waterproof membranes | ≥1.5 |
| Heat resistance/(100℃,2 h) | No flow, no drop, no slip | Resistance to artificial climate aging (wave length 300-400 nm,300kwh/M2, about 5000 h) | No wrinkle, degumming, shedding |
| Low-temperature flexibility | -40℃ No cracks | Solar reflectance | ≥0.80 |
Construction applications
• Substrate Prep: Thoroughly clean the substrate, removing any protrusions, sharp edges, or loose contaminants.
• Primer (if needed): For old color steel surfaces, brush or roll the matching water-based anti-rust primer for complete coverage.
• Sheet Installation: Position the sheet along the reference line, then firmly press with a rubber roller in forward and sideways motions to remove air.
• Overlap Sealing: Secure all sheet overlaps by applying firm pressure with a dedicated seam roller.
• Detail Reinforcement: Execute all necessary detail work and reinforcement following the specified standards.
Scope of Application
• Building Waterproofing: Ideal for roofs, underground structures, construction joints, and membrane edge detailing.
• Transport Infrastructure: Suitable for sealing joints in viaducts, metro tunnels, and underground passages.
• Industrial Cladding: For waterproofing, airtight sealing, and cushioning at sheet metal roof and panel joints.
• Multi-Material Bonding: Bonds common construction materials like cement, wood, PC, PE, PVC, EPDM, and CPE.
• Critical Sealing Applications: Used in waterproofing project joints, terminations, and complex-shaped areas.
• Building Systems: Provides sealing for doors/windows, damp-proofing between floors, and airtightness for ducts.
• Roofing & Metal Structures: Applied in leak repair on various roofs and sealing seams/cladding on industrial buildings.
