Product Description

The Polyethylene-Polypropylene (Polyester) Composite Waterproof Membrane is an advanced waterproofing material made by combining high-density polyethylene (HDPE), polypropylene (PP), and polyester (PET) fibers through a special hot-melt and extrusion process. This multilayer structure provides excellent tensile strength, flexibility, and durability, making it ideal for various waterproofing applications.

 

This membrane is available in TWO types based on the reinforcement layer:
1️⃣ Polyethylene-Polypropylene Composite Membrane (PP Type) – Reinforced with polypropylene fibers, offering high flexibility and adhesion performance.
2️⃣ Polyethylene-Polyester Composite Membrane (PET Type) – Reinforced with polyester fibers, ensuring higher tensile strength and stability for demanding waterproofing applications.

​

Key Features

✔ Superior Waterproofing – The multi-layer structure ensures a waterproof barrier, preventing leaks and moisture penetration in wet and indoor areas like kitchens, bathrooms, and under-roof installations (non-exposed).
✔ High Flexibility & Crack Resistance – Provides adaptability to structural shifts and movements, ensuring long-term durability without cracking.
✔ Tensile Strength – Reinforced with polyester or polypropylene, making it perfect for high-traffic and moisture-prone areas, such as kitchens and bathrooms.
✔ Chemical & Corrosion Resistance – Withstands moisture, detergents, and cleaning chemicals commonly found in kitchens and bathrooms.
✔ Anti-aging & UV Resistance – While it offers excellent UV resistance, the membrane should not be exposed to direct sunlight for long periods. It is perfect for protected roof areas or internal waterproofing.
✔ Environmentally Friendly – Safe, non-toxic materials make it ideal for residential and commercial applications.
✔ Customizable Thickness – Available in different thicknesses to meet specific project needs.​
