A rich history of slate quarrying
The site we are working on is a former slate quarry from which clay slate was extracted for almost six centuries. Slate quarrying at the site dates back to the 15th century, with evidence of industrial developments throughout the ages.
At its peak in the early 1900s, there were more than 6,000 quarrymen in the Bassin de l’Anjou, extracting around 250,000 tonnes of slate each year. This rich industrial history can still be seen today on the roofs of many buildings (churches, castles, etc.) along the Loire valley (in Tours, Amboise, Blois, Orléans, etc.) as well as in Paris and Normandy, where slate could be transported via the canals linking the Loire to the Seine.
The site is now located in the heart of an urban landscape. The quarry, like other sites, has become an industrial wasteland that the municipality is gradually rehabilitating to create new districts, cultural and sports facilities and tertiary areas.
As part of this redevelopment, Menard was appointed to improve the soil of an 11 ha plot between April and June 2022.
