Leakage Cause Analysis and Maintenance of Inverted Roofs Based on Engineering Cases
Taking a practical engineering case of an inverted roof in the cold winter region of northern China as the research object,this paper focuses on various reasons for the leakage problem of inverted roofs,the technical points of maintenance and construction plans,and quality control measures.Partial excavation is carried out on the original leaking roof to remove the accumulated water in the structural layer,and a double-layer exhaust pipe system is added.Finally,a combined waterproofing layer of 4 mm thick SBS modified bitumen waterproofing membrane and a 1.5 mm thick non-solidified rubber asphalt coating is installed as a whole.The repair effect of the roof is good.
