ABSTRACT:
A process is provided which produces a waterproof membrane and applies this waterproof membrane directly to a fixed substrate. The process includes the steps of providing a polymeric material; melting the polymeric material; forcing the melted polymeric material through a movable die, the movable die shaping the polymeric material melt into a film; moving the movable die across the fixed substrate; and applying the film directly to the fixed substrate forming a waterproof membrane. The polymeric material is one of those known in the art to be useful as roofing material. In a preferred embodiment, this process produces a sealing membrane which is applied to a roof of a structure forming a membrane effective to protect the structure from intrusion of water. In another aspect, an apparatus is provided which is capable of performing the process of this invention.
