Old Québec: Heritage foundations to protect

Old Quebec, a UNESCO World Heritage Site, is home to some of the oldest foundations in North America. While the historic buildings within the city walls are part of the institutional heritage, the adjacent residential streets – Faubourg Saint-Jean-Baptiste, Saint-Roch bas district, Côte-de-la-Montagne – have a real estate stock of stones and concrete where foundation problems are frequent. The dramatic topography of Quebec City, with its upper and lower towns separated by Cap Diamant, creates complex hydrogeological conditions.

Cap Diamant and natural drainage

The rocky promontory on which the upper town rests channels runoff water to the neighborhoods below. The foundations of Lower Town, particularly in Saint-Roch and the Old Port, are subject to this hydrostatic pressure amplified by the difference in level. Champlain Sea clay, found in the lowlands, retains water and maintains high moisture levels around the foundations. Foundation cracks in these areas are often accompanied by active infiltration, especially in the spring.

Old buildings and modern technology

Houses in Old Quebec and its suburbs have a variety of foundations: fieldstone, limestone masonry, poured concrete, and concrete blocks. Each type requires a tailored repair approach. Polyrethane or epoxy crack injection is effective on concrete foundations, while exterior waterproofing is suitable for foundations of any type. An inspection determines the optimal solution. Our contractors also serve Beauport and Charlesbourg.
