Mechanical durability of waterproofing membranes against elements of waterproofing membrane construction protection

Waterproofing membranes are one of the most commonly used waterproofing insulation materials. These can be found both in assemblies of roof constructions and substructures and are a key component for waterproofing systems. During design process it is necessary to select materials, elements and accessories so that mutual compatibility, waterproof effectiveness and reliability is ensured. In order to protect the main waterproofing layer a composition is therefore completed with construction protection elements, which are meant to prevent from a mechanical damage of waterproofing membrane. Mechanical stress and damage may become evident in variety of situations, which can be caused externally not only as an inappropriate ground bashing procedure but also as a consequence of improper waterproofing construction protection. In practice there are many cases of waterproofing system failures due to stress of elements with higher mechanical durability which affect elements with lower mechanical durability. The dissertation deals with an application of dimpled membranes protected by the layer of waterproofing membranes, which may due to stress and mutual compatibility result in waterproofing system failure and waterproofing reliability decrease. The dissertation is focused on mechanical durability of waterproofing membranes made of folio and modified bitumen membrane against damage from dimple membrane depending on stress category. First, possible waterproofing membrane damage from dimple extrusion is calculated and evaluated. The next part deals with verifying by experiment based on an effect of long-term static stress and short-term dynamic stress caused by ground bashing, where a measurement of ground bashing stress is performed. Experiment interpretation and an acquired knowledge provided the dissertation with an information what combination and order of particular layers results in higher risk of waterproofing system failure and waterproofing reliability decreas
