Commonly used for sheet-type waterproofing layers, asphalt waterproofing membranes include both base material and non-base material. Base material is made by impregnating thick paper, glass fiber cloth, asbestos cloth, cotton and linen fabrics, and petroleum asphalt. Rolled material, or non-base material, is made by rolling asphalt with asbestos, rubber powder, or other materials. Asphalt waterproofing membranes require drying to reduce internal moisture and facilitate subsequent processing.
