Description
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:2mm,3mm,4mm,5mm


Where to use
• Roofs or undergrounds;
• Pools, such as swimming pools, fire pools;
• Subways, tunnels, concrete road or bridge surfaces;
• Sewage plants, garbage burying projects;
• Penstocks.


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 50° C. It only can be put vertically in single-level.



FAQ
1.What is the main difference between SBS and APP modified asphalt/bitumen membrane?
Difference modifiers are used for the two types of membrane. SBS membrane is made with styrene-butadiene-styrene thermoplastic elastomer as the petroleum asphalt modifier, while APP membrane with atactic polypropylene orAPAO,APO as the modifier. Being made with different techniques, they have different properties in temperature tolerance. SBS membrane is more tolerant to low temperature, while APPmembrane is more suitable for hot areas.
2.What is width of the lap joint between patches of membranes in construction?
Usually7.5-8cm.
3.Are surfacing isolation materials optional for asphalt membrane?
Yes. Wehave different materials on upper surface,PEmembrane,fine sand Aluminum foil or mineral granules and on the lower surface,usually PE membrane.The products can be made to your order.
4.What's is the MOQ?---- Usually, the MOQ is 2000 square meters different items will be different, also we can adjust the MOQ according to your conditions.
5.Are the sample charged?-----We can provide you samples for quality inspection, according to our company policy, samples are free, we only charge the freight fee and the fright fee will be refund once you place the order.
6.How about the delivery time?-----Samples need 3-5 days, and loading time need 10-15 days after receiving the 50% deposit by T/T.
6.What is the Loading Port?-----Qingdao, China .
7.What is your Product Warranty?-----We guarantee the products customers receive are qualified. If there are any broken parts, please send us some detailed photos by email, and then we will send you the replacement parts according to actual conditions.
8.What kind of payments does we support?-----L/C, T/T.The payments term will be different in different countries and areas.
9.What is your trade term?-----EXW, FOB, CNF, CIF is also ok
10.What is your Product Warranty?-----We guarantee the products customers receive are qualified. If there are any broken parts, please send us some detailed photos by email, and then we will send you the replacement parts according to actual conditions.
