Sheet membrane waterproofing systems typically refer to thermoplastics, vulcanized rubbers, or rubberized asphalts.  All of these membranes come in roll form and can be used in vertical and horizontal applications.  Pre-fabricated at the factory, one of the distinct advantages of these systems is the uniform thickness achieved during the on-site installation.  Rubberized asphalts also have the advantage of being available in self-adhering rolls laminated with a polyethylene film.  Everclear Enterprises, Inc. routinely utilizes sheet membrane waterproofing systems in above and below-grade applications such as foundation walls, split slab construction, plaza decks, balcony decks, and planters.
