Tar felt sheets, or bituminous membranes, are flexible,, multi-layered waterproofing materials made by coating a core fabric (hessian, fiberglass, or polyester) with oxidized bitumen. Designed to prevent water leakage in roofs, basements, and terraces, these sheets are durable,, tear-resistant, and, often surfaced with sand or plastic for protection.
