Self-adhesive waterproofing membrane made of cross-laminated polymer film is a new-generation cold-applied waterproofing system designed for high-efficiency and safe construction applications.
It uses a high-strength cross-laminated polymer film as the carrier, combined with a high-performance butyl self-adhesive layer, and protected by a release film. The cross-laminated structure provides excellent tensile balance in both directions, significantly improving tear resistance, puncture resistance, and dimensional stability.
Unlike traditional torch-applied membranes, this product requires no open flame, no primer, and no heating equipment. Simply remove the release film and apply directly onto concrete or mortar substrates, achieving fast, safe, and environmentally friendly installation.
The advanced self-adhesive layer provides strong bonding performance and self-healing capability, effectively sealing micro-cracks and preventing water channeling, ensuring long-term waterproof reliability in demanding construction environments.
Key Features & Benefits
When waterproofing projects require high strength, easy installation, and reliable bonding performance, QINGYUAN Cross Laminated Film Self-Adhesive Waterproof Membrane provides a safe and efficient cold-applied waterproof solution for various construction applications.
High-strength cross laminated film structure provides excellent tensile strength and resistance to tearing and puncture damage.
Cold-applied installation requires no flame heating, improving construction safety and reducing fire risks on site.
Strong self-adhesive bonding creates a tight connection with concrete, mortar, and other substrates without peeling or hollowing.
Advanced self-healing adhesive layer automatically seals minor damage and micro-cracks to prevent water leakage.
Excellent resistance to water, acids, alkalis, and aging ensures long-term durability in underground environments.
High flexibility and elongation allow the membrane to adapt to substrate movement without cracking.
No primer or additional heating equipment required, simplifying installation and reducing labor costs.
Seamless adhesive joints help prevent water migration and improve overall waterproof reliability.
Suitable for underground structures, roofs, balconies, interior waterproofing, and renovation projects.

Standard Construction Process
Professional cold-applied installation methods ensure strong bonding, reliable sealing, and long-lasting waterproof protection for different building applications.
Base Surface Preparation
Clean dust, debris, loose materials, and sharp objects from the substrate. Repair uneven areas and ensure the surface is smooth and stable before installation.
Detail Reinforcement Treatment
Apply additional membrane layers to weak areas such as corners, pipe penetrations, drainage points, and construction joints for enhanced waterproof protection.
Membrane Installation
Remove the release film gradually and place the membrane according to positioning lines. Use a roller or scraper to press from the center outward and remove trapped air.
Overlap Joint Sealing
Remove the release film at overlap areas and firmly press the joints together. Ensure sufficient overlap width and complete sealing performance.
Protective Layer Installation
Apply protective layers such as cement mortar or concrete where required to prevent damage during subsequent construction.
Final Inspection & Waterproof Testing
Check membrane joints, bonding areas, and waterproof details to ensure the complete system meets project requirements.
