App Bitumen Membrane

App bitumen membrane is a type of waterproofing material that is created by utilizing modified asphalt, such as APP (atactic polypropylene) or APAO (amorphous polyalphaolefin), as the dipping layer and polyester or fiberglass felt as the base material. The dipping layer is then covered on both sides with an isolating material. The APP modified bitumen waterproofing membrane is more suitable for usage in hot locations due to its superior resistance to high temperatures as compared to SBS (styrene-butadiene-styrene) waterproofing membrane. The membrane forms a numerous composite waterproofing system with compatible materials, its seams joined firmly and reliably, and its integrity intact.

It is appropriate for waterproofing a variety of roof types in industrial and civil buildings, including green roofs, rooftop parking lots, inverted roofs, non-accessible roofs, accessible roofs, and insulated roofs. Additionally, it can be utilized for waterproofing in municipal engineering projects including sewage treatment plants, landfill sites, concrete pavement bridges, subways, and tunnels. For water-conserving structures like pools and water channels, it is strongly advised.

The base must meet the following fundamental specifications: it must be dry, clean, and smooth, with a moisture level of no more than 9%. It should also be evenly painted with base oil and left to dry before building begins.
The order of coil arrangement is as follows: the same height is first far away and then near; first high, then low span; Beginning at the bottom, stay on the same plane. The direction parallel to the roof crest is laid when the direction surface's slope is less than 3%; It is oriented toward a parallel or vertical ridge when the slope is between 3% and 15%; if the slope is greater than 15%, it is oriented toward a vertical ridge.
