Building Inspector in
Boisbriand

A planned suburban city on the North Shore, Boisbriand was shaped by the historic presence of the GM assembly plant and successive waves of residential development. From the worker bungalows of the 1960s to modern family neighbourhoods, this city offers a diverse housing stock on clay soil that directly influences the durability of its buildings.

Housing Profile

Boisbriand: industrial heritage
and family suburb.

Boisbriand's residential history is closely tied to the automotive industry. The earliest neighbourhoods were built for GM workers, followed by family-oriented developments in the 1980s-2000s and, more recently, the conversion of the former industrial site into modern residential quarters.

🏗
Worker Neighbourhoods (1960-1975)
Compact bungalows with basements, built for the industrial workforce. Period insulation, 100-amp electrical panels, aging cast-iron and copper plumbing. Many have been renovated over the decades with varying quality of workmanship.
🧱
Family Expansion (1985-2005)
Two-storey cottages and split-levels in planned neighbourhoods with parks and schools. Standard suburban construction with attached garages, brick cladding and finished basements. Clay soil causes settlement in several areas.
🔧
GM Site Redevelopment (2010+)
New residential quarters on the decontaminated former industrial site. Townhouses, condos and single-family homes built to current standards. Backfilled and graded terrain requiring particular attention to drainage and settlement.
Soil & Foundations

Marine clay
and former industrial site.

Boisbriand's soil consists of Champlain Sea marine clay, a soil sensitive to moisture variations. The former GM industrial site adds a dimension of backfill and reworked terrain that influences foundation behaviour in newer developments.

✓Unstable marine clay — Boisbriand's clay soil contracts in summer and swells in spring, exerting cyclical pressure on foundations. Homes from the 1960s-70s often show decades of cumulative movement.
✓GM site backfill — Construction on the former industrial site rests on terrain that was backfilled and compacted after decontamination. Uneven compaction can cause differential settlement in the first years after construction.
✓Deep frost penetration — Frost regularly reaches 1.5 metres in the Boisbriand area. Foundations that are not deep enough or have poorly protected footings undergo frost heave that cracks the walls.
✓Impermeable soil drainage — Clay prevents surface water from infiltrating naturally, causing accumulation around foundations. French drains and sump pumps are under constant demand in spring.
Common Findings

What we find
in Boisbriand.

Our inspections in Boisbriand reveal issues related to both the age of the building stock and the particular soil conditions in this city.

✓Active foundation cracks — Cyclical clay movement causes cracks that widen progressively. We measure their width and orientation to assess whether they are stabilised or still in motion.
✓Damp basements in bungalows — Homes from the 1960s-70s have degraded or absent waterproofing membranes. Water migrates through the concrete by capillarity, causing efflorescence, mould and odours in the basement.
✓Insufficient insulation — Original bungalows have R-8 to R-12 insulation, resulting in significant heat loss. Partial renovations create thermal bridges that promote condensation inside wall cavities.
✓Aging exterior cladding — Aluminium and vinyl siding from the 1980s-90s warps and loses its weathertight seal. Joints around windows and doors dry out, allowing air and water to penetrate.
✓Mixed plumbing materials — Many homes combine original copper or cast-iron pipes with PVC or PEX additions. Joints between different materials are weak points prone to leaking.
✓Settled garage slabs — Concrete driveway and garage slabs sink on the clay soil, creating slopes toward the house and cracks that widen with each freeze-thaw cycle.

FAQ

Questions about
Boisbriand.

Do the former GM-era neighbourhoods have specific concerns?+
Yes. The 1960s-70s bungalows feature minimal insulation, 100-amp electrical panels, aging plumbing and basements sometimes finished with period materials. A targeted inspection of original systems is essential.
Does the clay soil cause foundation problems?+
Clay soil is prone to seasonal shrinkage and swelling, causing cracks and differential settlement. Homes on poorly compacted fill are particularly vulnerable to these movements.
Are homes built on the former GM site safe?+
The site was decontaminated to current environmental standards before construction. New buildings meet modern codes, but the backfilled terrain can cause settlement in the early years.
