A study was performed on the prematurely degraded breakwater stone on the bay at Rivière-au-Renard and from the quarries in which they originate. The objective of the study was to highlight, through observation and laboratory testing, the probable causes of deterioration and to further propose new criteria to include in the specifications in order to minimize the number of problematic stones implemented in future coastal structures. The test for resistance to freezing and thawing cycles was carried out on slices of rock in order to recreate with more accuracy the observed degradation phenomena on the structures in place.
