MULTI-PLATE COMPLEX SHEET WITH WATERPROOF, ROOT BARRIER AND ADHESIVE CONDITION AND CONSTRUCTION METHOD THEREOF

摘要

According to a multi-plate complex sheet with waterproof, root barrier, and adhesive properties and a waterproofing method using the same of the present invention, the multi-plate complex sheet is composed of: a primary waterproof root barrier layer made of non-woven fabric and a PET film; a secondary waterproof root barrier layer made of the non-woven fabric and a synthetic resin film; and a triple structure of a melt point adhesive layer made of a melt point adhesive composition, wherein each has root barrier properties. The triple structure is not damaged completely at a time. The shock resistance, chemical resistance, and durability can be maintained in an exposing type waterproof construction method for lifting a coating layer in an upper part or in a non-exposing waterproof construction method for striking a protective mortar. And, there is no cracking of the waterproof root barrier in a joint, and construction costs are saved.
