Product Description
FortisMate™ Membrane Series
DSAB-CLF is a double-sided self-adhesive bituminous waterproof membrane reinforced with a premium CLF (Cross-Laminated Film) core, coated with high-tack modified rubberized bitumen on both sides and protected by silicone release liners.
Manufactured with high-quality modified bitumen and high-strength cross laminated film, the membrane delivers exceptional tensile strength, superior tear resistance, excellent dimensional stability, and reliable double-sided adhesion. It supports Dry Application(with Primer) and Wet Application(with Wet Cement Mortar) installation, ideal for basements, roofs, tunnels, bridges and high-reliability waterproofing projects.
Highlight: DSAB: Double-sided Self-adhesive Bituminous；CLF: Cross-Laminated Film, ultra-high strength, anti-tear, dimensionally stable.
Core Advantages
1. CLF Reinforcement, Extreme Strength
Unique cross-laminated structure provides ultra-high tensile strength, superior tear resistance, and excellent dimensional stability. Resists tearing even with notches; far stronger than ordinary HDPE/PET films.
2. Double-sided Adhesion & Skin-Type Waterproofing
Bonds tightly to substrate and overlaps. Forms integrated skin-type waterproofing, eliminates water channeling, prevents large-area leakage.
3. Localized Damage, Easy Maintenance
Any failure is confined; leakage points match damage points. Simple inspection and repair, low maintenance cost.
4. Unique Self-Healing Property
Automatically seals small punctures and micro-cracks, enhancing long-term waterproof reliability.
5. Safe & Cold-Applied Construction
No open flame, no hot melting, no solvents. Fire-safe, non-toxic, suitable for confined spaces.
6. Wet-Lay Compatible & Weather-Resistant
Installable on moist/damp/uneven substrates. No primer; rain-resistant construction, guarantees schedule.
7. Excellent Temperature Adaptability
Resists 70°C high-temperature flow and –20°C low-temperature cracking. Stable in extreme climates.
Application Range
Basement, roof and other place of industrial and civil construction.
