WATERPROOFING OF REINFORCED CONCRETE FLAT ROOF

2010-11-23  Proper design of falls in reinforced concrete flat roofs is most important in creating flow paths to suitable discharge points. For a roof to be effective, surface water should be discharged quickly without ponding or stagnation. Next, it is important to select the appropriate waterproofing membrane. As the roof is constantly exposed to direct sunlight and rain, it is likely to experience tremendous thermal stresses that will affect its physical properties and performance. Pre-formed waterproofing membranes generally will perform better than liquid applied membrane as it can bridge over cracks and gaps better. Also, as they are more resistant to indentations caused by traffic, they are suited for large flat roofs areas exposed to foot traffic. However, liquid-applied membrane is still preferred for small roofs and roofs

However, the complexity of the generalized approach, particularly for systems that do not meet the requirements permitting analysis by “direct design method” of the present code, has led many engineers to continue to use the design method of the 1963 ACI Code for the special case of two-way slabs
