3.0mm Exposed roof modified bituminous waterproofing membranes


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.



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.



·         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.



APP modified asphalt waterproof membrane material is packed in rolls with plastic bags.

 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.


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.
