APP modified asphalt waterproof membrane is a waterproofing modified bitumen base sheet consisting of atactic polypropylene (APP) or amorphous poly-α-olefin (APAO, APO)modified asphalt reinforced with polyester fiber covering with polyet-hylene 
surfacing.
Base sheet:polyester felt,glass fiber felt.
Upper surface isolation material: PE membrane, sand fine ,mineral granules, Aluminum foil.
Lower surface isolation material:PEmembrane.
Thickness:3mm,4mm,5mm

• Advantages
• The combination of polyester fiber and APP modified bitumen shows excellent performance on waterproofness;
• It will be a high-strength membrane to resist water;
• Puncture-resisting, tear-resisting, corrosion-resisting, mould-resisting and weather-resisting;
• Excellent tensile strength and elongation;
• Strong adaptability to substrate shrinkage, deformation and cracks;
• High temperature resistance(130° C);
• Convenient to apply: use heat fusion method in all seasons.

Application Method
Surface preparation
Surfaces should be dry, clean, smooth and free from any dusts, oil or loose particles. Cracks and surface irregularities need to be filled by polymer mortar.
Priming
Before membrane laying, substrate treating agent need to be brushed evenly and completely to cover all laying places.
Membrane laying
For adhesion between membrane and substrate or membranes, it can use hot melt method or cold adhesion method. According to application designs and specific applied parts, it can be applied by fully adhesion method, strip adhesion method and border adhesion method.
Sealing, fixing, and constraining on vertical surfaces
On vertical surfaces, fix with metal battens and seal with sealants for membranes.
Application on protection and isolation layer
After membrane laying, construct protection and isolation layer according to waterproof layer design.

Notice
APP waterproof membrane should be stored in well-ventilated place and avoid being exposed to the sun or rain. The temperature in stored places can not be higher than 60° C. It only can be put vertically in single-level.
