Edmundston and Madawaska: Foundations Tested by the Northwest
Edmundston, the heart of the Republic of Madawaska, is nestled at the confluence of the Madawaska and Saint John rivers, very close to the Quebec border. This geographical position gives it one of the coldest continental climates in New Brunswick, with winter temperatures regularly plunging below -30°C. The frost penetrates deep into the soil – often beyond one metre and a half – and remains there for five consecutive months, subjecting the foundations to prolonged and intense lateral pressures.
Edmundston’s hilly topography, between wooded hills and river valleys, creates soil conditions that vary from one neighbourhood to another. Areas built on alluvial river terraces are based on soils with a high clay and silt content, while higher neighbourhoods have more rocky soils. In both cases, foundation cracks are a recurring problem that homeowners need to keep a close eye on.
A Residential Park Marked by the Forest Industry
The development of Edmundston is intimately linked to the paper and forestry industry that attracted workers and their families throughout the twentieth century. The majority of the housing stock dates from the 1950s to 1980s, a period of sustained growth. These houses, built according to the standards of the time, are now reaching a critical age where the concrete of their foundation shows the cumulative effects of decades of Nordic freeze-thaw.
Basements are especially important in this region with long winters: they often serve as extra living space, a workshop, or storage. A cracked foundation that allows moisture to pass through, compromising not only the structure, but also the habitability and sanitation of these spaces that are essential to the daily lives of Madawaska families.
Proven Solutions for Madawaska’s Climate
Foundation crack injection is our main intervention in Edmundston. Carried out from inside the basement, it can be done in any season – a major advantage in a region where the ground is frozen for almost half of the year, making outdoor work impossible from October to May.
Flexible polyurethane injection is the resin of choice for Edmundston’s extreme conditions. Its permanent flexibility allows it to withstand the significant contraction and expansion movements that foundations undergo during large temperature variations. For structural cracks, we also use epoxy in cases where mechanical reinforcement is required, such as for slab cracks in garages subjected to de-icing salt.
