Non-Bituminous Polymer Self-Adhesive Waterproof Membrane

Product Overview

A pre-applied waterproofing system engineered for structural concrete integration. Three-layer composite construction:

1. Polymeric Carrier Sheet

2. Self-Adhesive Polymer Film

3. Anti-Bonding Release Layer

Bonding Mechanism:
The membrane interacts with fresh concrete through:

• Creep-Induced Penetration: Adhesive film migrates through release layer under hydrostatic pressure

• Molecular Interlock: Forms permanent IPS (Interpenetrating Polymer Structure) bonds

• Co-Curing: Creates monolithic seal with curing concrete

Key Features

1. Structural Integration

   • Seamless fusion with cast-in-place concrete (EN 14695)

   • Eliminates water migration paths ("water channeling effect")

2. Self-Contained Leak Management

   • Localized damage containment within 30cm radius (EN 1928 tested)

   • Pinpoint repairability without system compromise

3. Installation Efficiency

   • Substrate tolerance: ≤15% moisture content, no leveling required

   • 50% faster installation vs. conventional membranes

   • All-weather application capability

4. Eco-Safe Performance

   • Zero solvents/VOCs (ISO 16000 compliant)

   • Fire-resistant composition (NFPA 284)

5. Mechanical Performance

   • Tensile strength: ≥800 N/50mm (EN 12311-1)

   • Elongation: >80% (Class R, EN 495-5)

   • Peel adhesion: ≥4.0 N/mm (EN 14695)

6. System Economics

   • Eliminates screed layer (saves €8-12/m²)

   • Omits protective concrete topping (saves 15-20kg/m²)
