ABSTRACT:
A method of producing waterproofing membranes is disclosed. A tough, fibrous web or matting is saturated with a thermoplastic waterproofing compound to produce a predetermined minimum thickness on both the upper and lower surfaces of the membrane sufficient to provide adequate flow characteristics during installation of the membrane without excessive exposure of the support matting to deteriorating conditions during installation. Afterwards the coated membrane is cooled and inverted for further treating at least one of the exposed surfaces with additional material.
