Polyethylene Propylene (Polyester) Polymer Waterproofing Membrane​

Polyethylene propylene (polyester) polymer waterproofing membrane is a high-performance waterproof material widely used in construction projects. It features a multi-layer composite structure, with a modified polyethylene polymer resin layer serving as the waterproof core, flanked by polypropylene high molecular fiber layers for enhanced adhesion and durability. The typical width ranges from 1200mm to 1500mm, while thicknesses vary between 0.5mm and 1.5mm, offering flexibility to meet diverse project requirements.​
This membrane boasts several outstanding properties. Its high molecular fiber layers ensure excellent adhesion to both substrates and protective layers, especially when combined with polymer cement adhesive. The seamless bonding significantly reduces the risk of water seepage. Additionally, it can be applied on damp surfaces, allowing for immediate construction after rainfall, thus saving time. It excels in puncture resistance, aging resistance, and environmental friendliness, providing long-lasting waterproofing solutions.​
Its applications span various fields. In construction, it safeguards roofs, basements, bathrooms, and walls. In transportation, it is used for waterproofing roads, railways, and tunnels. It also plays a crucial role in environmental protection projects, such as landfills and sewage treatment plants, as well as in water conservancy projects.​
During installation, after preparing the substrate by ensuring it’s clean and even, the adhesive is mixed properly. Special attention is given to complex areas like corners, where additional layers are applied. The membrane is then fully adhered, with overlapping edges sealed to prevent leakage. Finally, a protective layer is added to enhance longevity. These features make it a reliable choice for waterproofing needs.
