Chicoutimi: foundation repair in the heart of the Saguenay
Chicoutimi, a central borough of the city of Saguenay, is built on the steep banks of the Saguenay River and its tributaries. The rugged terrain, with its steep slopes and tiered terraces, creates complex drainage conditions that directly influence the health of the foundations. The historic downtown districts, perched on the clay cliffs, and the more recent developments in the northern sector are experiencing distinct but equally worrying problems.
Sensitive clays of the Saguenay River
The bottom of the Saguenay Valley is lined with marine clays deposited by the Laflamme Sea. In Chicoutimi, these clays reach considerable thicknesses and are known for their sensitivity – that is, their tendency to suddenly lose their resistance when they are reworked. The sectors of Chicoutimi-Nord, Rivière-du-Moulin and the Rivière aux Vases basin are particularly concerned. The resulting differential settlements cause characteristic foundation cracks. Crack injection must take into account the nature of the soil to ensure a lasting repair.
The legacy of the 1996 flood
The Chicoutimi basin neighbourhood was among the most affected during the Saguenay flood in 1996. Many foundations were submerged for days, permanently altering their structural integrity. Saturated concrete became more porous, formwork rods corroded prematurely, and dormant cracks reactivated. Thirty years later, this damage continues to manifest itself. Window corner cracks and slab cracks are particularly common in these areas.
Services for the Borough of Chicoutimi
Flexible polyrethane injection is the preferred method for foundations on sensitive clay: it absorbs micro-movements while maintaining waterproofing. For more complex cases, the external waterproofing offers complete protection. Our contractors serve the entire Saguenay–Lac-Saint-Jean region, including La Baie, Jonquière and Alma.
