Common Errors in Brick Wall Crack Repair and Their Solutions


Masonry, an ancient skill, remains vital in the modern world, especially in Montreal, Laval, Longueuil, and across the South and North Shores. This article delves into frequent errors made during the repair of cracks in brick walls and proposes practical solutions.

Identifying the Real Cause of Cracks

Before any intervention, accurately diagnosing the cause of the cracks is crucial. Often, repairs are undertaken without a deep understanding of underlying issues like soil movement, structural problems, or natural wear and tear.


  • Professional Evaluation: Consultation with a masonry expert for a precise assessment.
  • Detailed Analysis: Using modern techniques like thermographic analysis to detect problems invisible to the naked eye.

Inappropriate Material Choices

Using materials incompatible with the existing ones often leads to long-term problems, such as recurring cracks or discoloration.


  • Material Compatibility: Select materials that harmonize with the original characteristics of the wall.
  • Superior Quality: Use high-quality materials that are resistant to weather and temperature variations.

Inadequate Repair Techniques

Improper repair methods can cause more damage. For instance, filling cracks without addressing the cause or using techniques not suited to old masonry.


  • Modern and Traditional Techniques: Adapt the repair technique according to the age and style of the wall.
  • Continuous Training: Ensuring that craftsmen are trained in the latest repair methods.

Neglecting Waterproofing and Insulation

Waterproofing and insulation are crucial for the durability of repairs. Neglecting them can lead to water infiltration and increased damage.


  • Advanced Waterproofing Systems: Use proven materials and waterproofing techniques to protect against moisture.
  • Regular Inspection: Conduct periodic inspections to quickly detect and address waterproofing issues.

Ignoring Safety Standards

Safety is paramount in repair work. Overlooking safety standards can endanger workers and occupants.


  • Compliance with Standards: Strictly follow local and national safety standards.
  • Safety Equipment: Ensure that the repair team is equipped with and uses the appropriate safety gear.
