Self-Adhesive Bituminous Waterproofing Membrane consist of asphalt, polymers, and tackifiers, and may also include mineral stabilizers. These products can be reinforced with fiberglass, polyester, or a combination of both materials. Typically, products intended for outdoor use are finished with mineral granules, coatings, films, or other opaque surfaces. The self-adhesive layer is safeguarded by a release film or paper, which is removed at the time of installation.

One of the key benefits of self-adhesive membranes is their labor-saving application, which eliminates the complexities associated with torching, mopping, or using liquid adhesives. The absence of kettles or torches during installation makes the process less disruptive for building occupants.
