What Is APP Bitumen Membrane and Why Is It Used?

APP bitumen membrane is a type of waterproofing material. It is used to protect roofs, basements, and walls from water damage. The full name of APP is Atactic Polypropylene, which is a type of plastic added to bitumen (a black, sticky material made from crude oil). When APP is mixed with bitumen, it becomes strong, flexible, and resistant to heat. This makes it a perfect material for protecting buildings from water leaks, especially in hot places like Dubai.
