The APP modified bitumen waterproof membrane is an APP (Atactic Polypropylene or Amorphous Polyolefin (APAO, APO)) type modified bitumen membrane, which is reinforced with heavy duty polyester felt, finished with sands on the upper surface and polyethylene film or sands on the lower side. The road-bridge application design allows binder course to be applied on the membrane top at a high temperature without the risk of being damaged, shrinking or punctured. It withstands mechanical stress laying of road surfacing and when vehicle traffic in service. The excellent adhesivity and flexibility make it to adapt and move with the decks as they move and flex.

Features
☆  Excellent mechanical strength without breaking or cracking during installation and when in service.
☆  Superior adhesion to concrete underneath and to binder course on top, adaptability to deformation, no slopping                   or sliding in service
☆  Resistance to high temperature, no damage during binder course installation
☆  High mechanical strength and puncture resistance to allow for paving equipment to be driven and parked
☆  Resistance to water and salt solutions, and to freeze-thaw cycles

Uses
* Waterproof engineering for highway, airports, railway, bridges, parking lots
* For traditional asphalt pavement as well as gussasphalt
* New or renovation concrete reinforced bridges

* Dynamic load engineering projects
