APP modified bitumen waterproofing felt - CH-05

Description

Chenhua APP modified bitumen membrane is a kind of flexible sheet waterproof material,

which uses amorphous polypropylene (APP) modified asphalt as a dipping and

covering modifier, whose upper surface is coated by PE film, fine sand, mineralgrain

or aluminum foil or other isolating materials.

The compound is a mixture of distilled bitumen, plastomers and elastomers

which gives the membrane excellent resistance to heat aging and weathering.

Type

Features

• Integrated advantage properties of spunbonded polyester substrates

and APP modified asphalt, wonderful integrated properties.

• High strength and good property to stand against water pressure water
• High tensile strength and elongation rate, strong adaptability for substrate

shrinking distortion and cracks

• Good construction performance, with firm and enduring joints

Applied Range

• All kinds of building roof engineering projects, treading, non-treading, heat preservation,

planting building surfaces, roof parking lots, and converted buildin surfaces

• All kinds of underground waterproof or dampproof engineering projects
• Bridge surfaces of subways, tunnels, or concrete roads, sewage treatment and

garbage burying projects and other municipal engineering waterproof projects

• Water spraying pools, swimming pools, penstocks, water pools, and so on.

Uses

1) Make sure the roof deck smooth, clean and dry(Moisture<9%),then apply the surface

of roof deck homogeneously with a kind bitumen paint till dry to start application.

2) There are two methods in application:

One way is by heating and melting method---

Heat the polyethylene film of the membrane and roof deck surface by heating

and melting method to be nearly melted(not flowing), then install the membrane

fully bonded to the roof deck with overlaps of 5-10cm.

The other way is by cold adhesive method---Pour the cold adhesive homogeneously on the roof deck then roll the membrane to install

it to be fully sticked to roof deck. By heating and melting method and by cold adhesive

can be used in alternation in application as requested.

3) After application, a full serious inspection is required to make sure no air bubble,

no fold, no falling away etc to guarantee the waterproof life.
