The invention is directed to a bond-compatible composite membrane comprising a first self-adhesive material layer and a second rough fabric layer, and its use as an intermediate layer between a building structure substrate and exterior finishing materials. Unlike conventional composite membranes, the bond-compatible composite membrane has a rough surface that allows bonding materials to adhere to it. Therefore, mechanical devices are not needed to attach the exterior finishing materials to the building structure.
