Abstract
Analysis of roof membranes damaged by mechanical and climatic loads – pilot research
Highlights
Fundamental property of roof is the ability to resist negative atmospheric conditions during its whole lifetime
Two types of analysis have been done in this research: analysis of mechanical damage on membranes caused by human factor and its influence on membrane waterproofing, analysis of hailstorm impact on membranes subjected under laboratory temperature 20 °C placed on different base material
The biggest distinctions can be observed on the PVC-P and ethylene propylene diene monomer (EPDM) foils which were tested as reinforced and unreinforced
Summary
Fundamental property of roof is the ability to resist negative atmospheric conditions during its whole lifetime. Certain potential risks can cause damage of waterproof membrane within realization of a building. In the all phases of project it is necessary to have in mind that except of traditional designed loads (people, snow, etc.) human behaviour factor is there This special load is unpredictable and it cannot be specified in design process. One little damage on the membrane can cause really huge problems on the whole new building in the nearest future. Special climatic conditions as hailstorm impact could be able to cause huge damage of membrane placed on some certain. Especially density and elasticity of underlay material can influence response of membrane under immediate impact of hails. The effort is to find the right way of explaining this influence between damages and whole waterproof functionality of roof
