PVC High-Polymer Waterproof Membrane

• High Durability: Aging resistant, long service life (up to 50 years).

• High Mechanical Strength & Puncture Resistance: Excellent resistance to puncture and tearing.

• Corrosion Resistance: Resistant to acid, alkali, salt, and root penetration; chemically stable.

• Eco-friendly & Non-toxic: Pure material, environmentally safe, recyclable.

• Easy Installation: Loose-laid method, unaffected by substrate moisture, high construction efficiency.

Suitable for landfill, sewage treatment plants, artificial lakes, reservoirs, tunnels, basements, and other waterproofing and anti-seepage projects; particularly for municipal and environmental protection projects with strict requirements.

• Substrate Preparation: Flat, compacted, free of sharp objects.

• Laying Method: Loose-laid; membrane naturally unrolled; overlap ≥ 100mm.

• Welding: Use specialized welding machine for double seam hot-melt welding.

• Detail Treatment: Pre-fabricated parts or additional layers for inner/outer corners and pipe penetrations.

• Quality Inspection: Weld seam quality checked by air pressure test.

Store in ventilated, sun- and rain-protected area; storage temperature ≤ 45℃.

Rolls of different types and specifications should be stacked separately.

Max stack height: 3 layers when flat; single layer when vertical. Avoid contact with acids, alkalis, oils, or organic solvents.

Shelf life: 1 year under normal storage. Transport carefully to avoid tilting or horizontal pressure; cover if necessary.

• Substrate Requirements: Flat, no sharp protrusions.

• Welding Conditions: Ambient temperature ≥ 5℃; take wind protection measures in strong wind.

• Finished Product Protection: Cover immediately after installation to prevent damage.

• Professional Construction: Must be operated by trained professional team.
