Foundation Crack Repair on the North Shore

Permafrost in some northern areas and large temperature differences between seasons cause significant ground movements. Fissure Expert serves the North Shore to offer reliable foundation crack injection and exterior waterproofing solutions adapted to this vast and diverse territory.

Côte-Nord: foundation repair over a huge territory
Quebec’s North Shore stretches for more than 1,300 km along the St. Lawrence River and Gulf, from Tadoussac to Blanc-Sablon. This vast territory, one of the northernmost in inhabited Quebec, has extreme geological and climatic conditions for the foundations. The Canadian Shield, which outcrops over most of the region, is covered by thin glacial deposits and acidic forest soils that create a chemically aggressive environment for concrete.
Baie-Comeau and Sept-Îles: The Challenges of Industrial Cities
The two main cities of the North Shore, Baie-Comeau and Sept-Îles, were built to serve the major industries – aluminum in Baie-Comeau, iron ore in Sept-Îles. Their housing stock, largely built in the 1950s to 1970s, was quickly erected to house the workers. These 50 to 70-year-old foundations, exposed to winters with temperatures regularly below -30 °C and freezing penetrating more than 1.8 meters deep, are now showing signs of advanced deterioration. Foundation cracks are aggravated by the salt spray of the river.
Discontinuous permafrost and its effects
In the eastern portion of the North Shore, beyond Havre-Saint-Pierre, some areas have discontinuous permafrost. Even where perma-frost is absent, the exceptional frost depth of the region – sometimes exceeding two meters – exerts considerable pressure on the foundations. Frost uplift literally lifts structures and then rests them unevenly as they thaw. The injection of foundation cracks must be carried out with materials capable of withstanding these extreme thermal amplitudes.
Specialized services for the entire North Shore
Flexible polyrethane injection is the technique best suited to northern conditions: it retains its flexibility even in extreme cold and absorbs structural movements caused by intense frost. For concrete block foundations of older houses, external waterproofing provides maximum protection. Our specialized contractors operate from Tadoussac to Sept-Îles. A foundation inspection is the recommended first step.
