| Abstract: | This paper presents a study of PVC-P waterproofing membrane Specimens. The Specimens
were taken from different segments of a flat roof after a service life of 11 years. The reason for
analysing the condition of the Specimens was the apparent degradation of the waterproofing, which
no longer guaranteed the watertightness of the roof. The analysis of the performance of the Specimens
was based on the control of the mechanical properties, which were compared with the declared
values. The mechanical properties of the degraded PVC-P waterproofing membranes with a polyester
mesh backing, which are prescribed by the standards, do not usually deviate from the declared
properties. This often poses a problem for liability and warranty claims due to the poor quality
of the waterproofing membrane. There may be several causes of degradation of PVC-P. For this
reason, in this paper, we present the possibility of controlling the properties of PVC-P waterproofing
membranes using cyclic dynamic fatigue, microstructure analysis using scanning electron microscopy
(SEM) and energy dispersive spectroscopy (EDS). The results show that the cause of the deterioration
of the PVC-P waterproofing membranes is often related to dehydrochlorination of the polymer.
However, the deterioration of the mechanical properties of the PVC-P waterproofing membranes can
be successfully demonstrated by cyclic dynamic fatigue. |
