RapidBond™ Cross-Laminated Self-Adhesive Waterproof Membrane

Product Overview
A cold-applied composite membrane combining cross-laminated high-density polyethylene (HDPE) film with polymer-modified self-adhesive rubberized asphalt. Engineered for:

• Instant concrete substrate bonding via pressure-sensitive adhesion

• Permanent mechanical interlock with cementitious surfaces through silicate hybridization

• Exceptional dimensional/thermal stability (-30°C to +100°C)

• UV resistance (6-month exposed installation window)

Key Features

1. Structural Reinforcement

   • Biaxially oriented HDPE grid eliminates puckering/wrinkling

   • 200% higher tear strength vs. standard films (ASTM D1004)

2. Advanced Adhesion Technology

   • Self-healing sealant repairs minor punctures

   • Silicate-CSH gel formation creates permanent substrate bond

3. Climate Resilience

   • Withstands thermal cycling from -30°C to +100°C

   • UV stability: 6-month unprotected exposure rating

4. Installation Efficiency

   • 1m-2m widths minimize seams

   • Compatible with hot-air/variable-temperature application

   • Zero open-flame requirement

Performance Specifications

• Peel strength: ≥3.0 N/mm (EN 12316-1)

• Dimensional stability: ≤0.5% @ 80°C (EN 1107-2)

• Concrete bond strength: >2.5 MPa (EN 1542)

Applications

• Non-exposed roofs & underground structures

• Cut-and-cover metro/tunnels

• Water reservoirs/canals

• Flame-restricted construction zones

Installation Note: Bond to substrate with cement mortar; lap joints via self-adhesive sealing
