At Zhejiang Zhongcheng Packing Material Co., Ltd., we are committed to delivering high-quality construction materials that combine innovation, durability, and efficiency. Our Waterproofing Film for Construction is engineered to provide superior protection against water penetration, ensuring the longevity and integrity of various building structures.
Product Functions and Uses
Our waterproofing film serves as a critical barrier against moisture, water infiltration, and related structural damages.
Its primary functions include:
- Moisture Barrier: Prevents water vapor and liquid from penetrating concrete, masonry, or roofing materials.
- Structural Protection: Safeguards foundations, walls, and roofing from water-induced deterioration, cracking, and corrosion.
- Energy Efficiency: By reducing water ingress, the film helps maintain thermal insulation performance in buildings.
- Versatile Application: Suitable for use in roofing, basements, tunnels, bridges, swimming pools, and other water-sensitive structures.
The film can be applied in both new constructions and renovation projects, providing long-term waterproofing solutions.
Product Features
Our waterproofing film stands out in the market due to the following features:
- High Tensile Strength: Resistant to tearing, punctures, and deformation during construction or installation.
- Excellent Water Resistance: Completely impermeable to water, ensuring reliable protection in both wet and humid environments.
- UV Resistance: Durable under prolonged sunlight exposure, preventing premature aging or degradation.
- Flexibility: Conforms easily to irregular surfaces, corners, and joints without compromising effectiveness.
- Chemical Resistance: Resistant to common construction chemicals, cement, and salts, ensuring stability in harsh conditions.
- Environmentally Friendly: Non-toxic, safe for workers, and recyclable after use.

Product Usage Instructions
For optimal performance, proper installation of the waterproofing film is essential:
- Surface Preparation: Ensure the surface is clean, dry, and free from debris, sharp edges, or protrusions.
- Cutting and Positioning: Unroll the film and cut to the required dimensions, leaving appropriate overlap at seams (typically 50–100 mm).
- Fixing the Film: Attach the film using mechanical fasteners, adhesive, or heat welding, depending on the project specifications.
- Sealing Joints: Overlaps and seams should be securely sealed to prevent water infiltration.
- Inspection: Conduct a visual inspection to verify full coverage and absence of damage before covering with additional layers or backfill.
- Maintenance: Periodic inspection is recommended in exposed applications to ensure long-term performance.
