Product overview


Dayu®APP plastic body modified asphalt waterproofing membrane, is a hot melt waterproof membrane composed of tire base, plastic body modified asphalt gum, surface material.


l fetal baseHigh quality filament polyester felt.

l Glial: APP (random polypropylene) as a modifier to modify the petroleum asphalt, prepared into a dip coating gum, evenly coated on both sides of the tire base.

l Surface materialPolyethylene film, fine sandorMineral pellets.




Product Features


High tensile strength, strong tear resistance, good dimensional stability, excellent mechanical properties, and strong resistance to breakage.

Excellent high temperature resistance, high temperature 130 ℃ does not flow.

Mature hot melt method construction process, molten asphalt body lap, reliable bonding, lap firmly, suitable for all seasons.

It can form a composite waterproof layer with other compatible coatings or coils to meet higher grade waterproof requirements.




Specification classification


Upper surface material

Polyethylene film (PE)/S (fine sand)/M (mineral pellets)










Scope of application


It is suitable for industrial, civil, municipal and other construction projects, including administrative, residential, commercial, scientific research, medical, school, grain depot, pipe gallery and other buildings.

It is suitable for road and bridge waterproof engineering, high temperature industrial plant roof waterproof engineering, or roof waterproof engineering of buildings in high temperature areas in the south.

The membrane with mineral granules can be used for exposed waterproofing of non-human roofs.




Construction process


L grass-roots requirements: solid, dry, free of sediment, laitance, no empty drum, loose, sand and other phenomena.

L interface treatment: uniform spray (roll) coating matching base treatment agent, improve the coil and the adhesion of the base.

L trial laying of coiled material: lay the coiled material flat on the base surface, align the elastic line or the overlapping edge of adjacent coiled material, adjust the overlapping width, let stand for a period of time to release the stress and then roll back.

L hot melt paving: bake the lower surface and base surface of the coil with a flame, push the roll paving coil forward in time after the colloid is melted, and compact and exhaust while it is hot to make the coil and the base closely bond.

L body lap joint: paving and pasting synchronous rolling lap joint edge to extrude 5~8mm molten asphalt (regarded as reliable lap joint).
