APP Membrane
APP Membrane APP (Atactic Polypropylene) Membrane waterproofing refers to a type of waterproofing system using APP-modified bitumen membranes. These membranes are made from a blend of bitumen and APP, a type of synthetic polymer that enhances the bitumen's properties. APP waterproofing membranes are applied to surfaces like roofs or foundations and offer excellent resistance to UV rays, temperature extremes, and aging. They provide a durable, flexible, and effective barrier against water ingress.
