Product Application Description

APP modified bitumen waterproof membrane is a high‑performance waterproof membrane coated with APP (Atactic Polypropylene) modified bitumen, using polyester mat or glass fiber mat as reinforcement substrate. Its surface can be covered with PE film, sand particles, aluminum foil and other protective layers.

It is applicable to various building roof projects, including flat roofs and sloped roofs for exposed or non‑exposed waterproofing systems. Waterproofing for bottom slabs, side walls and top slabs of underground structures, basements and civil air‑defense projects. Waterproofing for municipal infrastructure such as subways, tunnels and urban utility tunnels. Waterproofing and moisture‑proofing for bridges and parking lots. Waterproofing for industrial plants and warehouses, also suitable for renovation and repair of old roofs.

Technical Parameters

Product Advantages

Excellent high‑temperature resistance: APP modified bitumen features good thermal stability with no flow at high temperatures. It fits hot and sunny southern regions and supports partial exposed application. Strong anti‑aging performance: Resistant to UV radiation, weathering and ozone, ensuring long service life under long‑term outdoor conditions. Superior mechanical properties: Polyester‑reinforced version delivers high tensile strength and large elongation, resisting substrate cracking and accommodating minor structural settlement and cracks. Good chemical resistance: Resistant to acid, alkali and underground water corrosion, maintaining stable performance in underground working conditions. Versatile construction methods: Hot‑melt application is available; other construction methods are compatible for selected grades. Firm overlapping joints ensure reliable and mature installation. Multiple reinforcement options: Polyester mat for areas subject to large deformation; glass fiber mat provides good dimensional stability with cost‑effective performance to meet various project budgets and working conditions. Various protective surface options: Sand‑finished surface can serve as direct protective layer; aluminum‑foil surface reflects sunlight to reduce roof temperature.
