Bituminous Waterproofing App Membrane

APP membrane is a popular waterproofing material made from bitumen modified with atactic polypropylene (APP), a type of plastic. It's commonly used for waterproofing flat roofs, basements, and other structures in Kenya due to its durability, flexibility, and UV resistance. APP membranes are easy to work with, especially when it comes to melting and spreading on surfaces. They come in rolls and are typically applied using heat or cold adhesives.
