Abstract
Disclosed is a prefab waterproof structure and method for fabricating the waterproof structure according to a dry process. The prefab waterproof structure comprises a base sheet layer including a plurality of base sheets, a hard sheet layer including a plurality of hard sheets, and a cover sheet layer including a plurality of cover sheets. The base sheet layer, the hard sheet layer and the cover sheet layer are spread in order on the base surface of concrete. And the sheet layers may be formed by arranging and binding the pre-made sheets. The present invention can improve durability, toughness, chemical resistance, etc significantly, shorten a work period by omitting a hardening process and resolve many environmental problems.
