Grand-Mère: foundations inherited from the Mauritian industrial era
Grand-Mère, now part of Shawinigan, is a city born from hydroelectricity and the paper industry at the beginning of the twentieth century. Perched on the rocky banks of the Saint-Maurice River, the city owes its name to the rock in the shape of an old woman’s face that was located in the river. The subsoil of Grand-Mère is mostly rocky – the Canadian Shield outcrops in many places – with pockets of sand and glacial till in the depressions.
Rock and complex drainage
The presence of rock near the surface creates complex drainage situations. Rainwater and meltwater cannot seep into the rock and accumulates in depressions around the foundation. In winter, this water freezes and exerts lateral pressure on the walls. Homes built directly on rock can also experience vibrations transmitted by industrial operations in the sector. Foundation cracks in Grand-Mère are often fine but persistent, allowing water to seep in at the slightest thaw.
Workers’ assets and ageing foundations
Grand-Mère’s housing stock dates mainly from the period 1920-1970. These century-old or near-century-old houses have foundations made of stone, concrete blocks or period formwork concrete, often of lower quality than current standards. Crack injection by flexible polyrethane is effective even on these old concretes. External waterproofing provides long-term protection for these vulnerable foundations.
