COMPLEX WATER PROOFING METHOD OF THE ROOF OF THE BUILDING

摘要

A multi-functional complex waterproofing method for a roof is provided to secure the durability of a waterproofing layer and to maximize utility by improving a walking feel and an appearance of the roof. A multi-functional complex waterproofing method for a roof includes the steps of: forming a first waterproofing layer(10) in such a way that nonwoven fabric is impregnated on an asphalt sheet; forming a second adiabatic/waterproofing layer(20) such that a hard polyurethane foam is sprayed on the first waterproofing layer as a coating water proofing material; forming a third adiabatic/waterproofing layer(30) such that polyurethane adhesives are coated on the second adiabatic/waterproofing layer to adhere artificial grass to the adiabatic/waterproofing layer; and increasing utility of a rooftop by executing an artificial grass on the third adiabatic/waterproofing layer as a protection finishing layer(40).
