HDPE Non-Asphalt-Based Self-Adhesive Membrane Waterproofing Membrane is a specialized waterproof material developed for pre-laid building waterproofing applications. Composed of polymer sheet, polymer self-adhesive membrane, and anti-adhesive layer, this non-asphalt-based polymer pre-laid waterproofing membrane is designed to integrate seamlessly with concrete structures.

• Thickness: 1.2mm, 1.5mm
• Width: 1000mm, 2000mm
• Waterproof Category: Polymer Type
• Application Fields: Bottom Slabs, Trenches
• Brand: Qilu Zhuowang
• Origin: Weifang, Shandong
• Feature: Pre-Laid Bonding
• Shape: Rolled Sheet
• Product Material: HDPE (High-Density Polyethylene)

Under pressure, the polymer self-adhesive membrane and unset cement slurry in concrete creep and penetrate the anti-adhesive layer, forming effective mutual bonding with strong intermolecular forces. After concrete curing, the gaps between the polymer pre-laid waterproofing membrane and the main structure are permanently sealed, eliminating water channeling paths.

• Waterproofing of basements, subways, tunnels and other underground structures
• Projects with high waterproofing requirements
• Green roof waterproofing systems
• Gas leakage prevention for underground gas and biogas containment

• Superior pre-laid bonding performance
• Reliable adhesion with easy maintenance
• Low base layer requirements, reducing construction time
• Excellent cost-performance ratio

1. Clean the base layer thoroughly
2. Snap layout lines on the base layer
3. Lay the waterproofing membrane
4. Properly lap the membrane joints
5. Handle detailed connection nodes
6. Conduct self-inspection, repairs and final acceptance
7. Tie steel reinforcement bars
8. Pour concrete structure
