The Main Causes of Cracks in Brick Walls: A Comprehensive Guide for Residents of Montreal, Laval, Longueuil, South Shore, and North Shore


As masonry experts in Montreal, we often encounter questions regarding cracks in brick walls. This common phenomenon in the Montreal, Laval, Longueuil, and the South and North Shores areas deserves special attention. In this article, we will deeply explore the main causes of this issue and offer tailored solutions to our clients.

Origins of Cracks in Masonry

1. Soil Movement

  • Soil Expansion and Contraction: Temperature and moisture variations cause the soil to expand and contract, which can lead to movements in the foundations and, consequently, cracks in the brick walls.
  • Soil Quality: Clay or poorly drained soils in Montreal and surrounding areas can also cause differential settling, affecting the stability of structures.

2. Aging and Natural Wear

  • Material Erosion: Over time, construction materials undergo natural erosion, which can weaken the walls and make them more susceptible to cracking.
  • Freeze-Thaw Cycle: Montreal's climate is characterized by freeze-thaw cycles that can cause cracks due to the repeated expansion and contraction of materials.

3. Structural Issues

  • Design and Construction: Errors during design or construction can lead to structural weaknesses, leading to the appearance of cracks.
  • Damage from Heavy Loads: Excessive weight on structures, like an overload on roofs during winter, can also be a factor.

4. External Influences

  • Nearby Construction Work: Vibrations caused by nearby construction work or heavy traffic can induce cracks in brick walls.
  • Water Infiltration: Water seeping into the joints or behind the bricks can cause significant damage, especially when it freezes.

Prevention and Repair

  • Regular Inspections: Regular inspections by professionals can help detect problems early and avoid costly repairs.
  • Proper Maintenance: Regular maintenance of joints and quick repair of small cracks can prevent more significant damage.
