Renovation of Flat Roofs without the Need to Remove the Existing Roof Deck

Abstract

The solution principle: ,,Renovation of flat roofs without the need to remove the existing roof deck'' is based on the calculation procedure of W. van der Spoela, based on the point or line perforation, when diffusion-open termination of the new waterproofing layer allows expansion of the water vapor from the existing layers. It leads to the improvement of the thermal-technical properties of the original thermal insulation during a short time. The aim of the whole project is to create complex methodology enabling sophisticated approach to the design solution for the repair or renovation of roof deck without the need for their complete remove. The project leads to considerable cost saving and loads by reduce of ecological loads by landfilling or waste disposal. Index Terms-Flat roof, renovation, perforation, moisture, waterproofing layer, reconstruction, roof deck, thermal insulation layer I.Jiří Rozsypal is a authorized engineer in the field of civil engineering, graduate of the master's degree program at the Faculty of Civil Engineering of the Brno University of Technology and specialized studies at the Institute of Forensic Expertise of the Brno University of Technology, a PhD student at the Institute of Building structures, Faculty of Civil Engineering, Brno University of Technology. He deals with the issue of building insulation with a focus on roofs and ventilated facades.
