  1. Bricks: An Overview

Bricks are a timeless construction material, revered for their robustness, aesthetic charm, and resistance to fire. Created from clay or shale and solidified through a high-temperature firing process, bricks have inherent vulnerabilities, including a porous nature that can absorb and retain water. This is a critical factor in understanding how poor drainage can impact bricks.

  1. The Science Behind Water and Bricks

As a porous material, bricks absorb water. This is usually not an issue during dry conditions, as bricks have a natural ability to evaporate absorbed water. However, in scenarios where water exposure is prolonged due to poor drainage, complications can arise. The trapped moisture within the bricks can lead to significant structural damage, including cracking and splintering.

  1. The Impact of Poor Drainage on Bricks

Poor drainage can expose bricks to continuous moisture, leading to multiple problems:

  1. Freeze-Thaw Damage: In areas with cold winters like Montreal, the water absorbed by bricks can freeze. As water expands upon freezing, it can exert pressure on the brick's interior, leading to cracks or splintering.
  2. Salt Crystallization: When bricks absorb water, any dissolved salts within it are also absorbed. As the water evaporates, the salts crystallize, exerting internal pressure that can cause cracking and spalling.
  3. Efflorescence: As moisture evaporates from bricks, it leaves behind salt deposits on the surface, resulting in a white powdery substance known as efflorescence. While this does not directly cause cracking or splintering, it is a visual indication of excessive moisture in the bricks.
  4. Spotting the Signs of Water Damage in Bricks

Recognizing the signs of water damage can help you take preventive action. Look for visible cracks, spalling, or efflorescence. Bulging bricks, damp patches, or mold and mildew are also tell-tale signs of water-related damage.

  1. How to Prevent Brick Damage with Proper Drainage

Several strategies can be implemented to ensure proper drainage and prevent moisture-related brick damage:

  1. Landscaping: The land around your home should slope away to allow water to drain effectively.
  2. Gutters and Downspouts: Regularly clean and maintain your home's gutters and downspouts to ensure they direct water away from the structure.
  3. Water-Resistant Barriers: Installing these barriers in walls can prevent water from reaching the bricks.
  4. Quality Mortar Joints: Well-maintained mortar joints can effectively repel water, reducing the amount absorbed by bricks.
  5. Repairing Damaged Bricks Due to Poor Drainage

If your bricks are showing signs of water damage, it's crucial to act promptly. Depending on the extent of the damage, repair strategies can range from minor repointing work to brick replacement. Addressing the underlying drainage issue is equally important to prevent future damage.
