As a business owner in Ontario, maintaining the integrity of your commercial property is crucial. One often overlooked aspect of building maintenance is brick repair. Whether you own a historic downtown storefront or a modern industrial complex, understanding the ins and outs of commercial brick repair can save you time, money, and headaches in the long run. In this comprehensive guide, we’ll explore everything you need to know about keeping your brick structure in top condition.
1. Introduction to Commercial Brick Repair
1.1 Importance of maintaining commercial brick structures
Brick buildings are known for their durability and longevity, but they’re not invincible. Regular maintenance and timely repairs are essential to preserve the structural integrity, aesthetic appeal, and value of your commercial property. Neglecting brick maintenance can lead to costly repairs, safety hazards, and even legal liabilities.
1.2 Common signs of brick damage in commercial buildings
Identifying brick damage early is key to preventing more serious issues. Look out for these common signs:
- Visible cracks in bricks or mortar
- Spalling or flaking of brick surfaces
- Efflorescence (white, powdery substance on brick surfaces)
- Bulging or bowing of brick walls
- Water stains or dampness on interior walls
2. Types of Commercial Brick Damage
2.1 Cracking and spalling
Cracks in bricks or mortar can occur due to various factors, including foundation settlement, thermal expansion, or excessive moisture. Spalling, where the face of the brick flakes off, is often caused by freeze-thaw cycles or the use of improper materials during construction.
2.2 Mortar deterioration
Over time, mortar can erode due to weather exposure, leading to gaps between bricks. This compromises the wall’s structural integrity and allows water to penetrate, causing further damage.
2.3 Water damage and efflorescence
Water infiltration is a major culprit in brick damage. It can lead to efflorescence, a white, powdery substance that appears on brick surfaces when water-soluble salts are brought to the surface through evaporation.
2.4 Structural issues
More severe problems, such as bowing walls or foundation settlement, can cause significant brick damage and require immediate attention from a structural engineer.
3. Assessing Brick Damage in Commercial Buildings
3.1 Visual inspection techniques
Regular visual inspections can help catch brick damage early. Look for:
- Cracks larger than 1/16 inch
- Mortar that can be easily scraped away
- Misaligned bricks
- Damp spots or water stains
3.2 Professional assessment methods
Professional masons use various tools and techniques to assess brick damage, including:
- Moisture meters to detect hidden water issues
- Thermal imaging cameras to identify temperature variations
- Hammer testing to check for hollow spots
3.3 When to call in experts
While minor issues can often be addressed by property owners, it’s crucial to involve professionals for:
- Large-scale damage or deterioration
- Structural concerns
- Historic building restoration
- Complex water infiltration issues
4. Commercial Brick Repair Techniques
4.1 Repointing and tuckpointing
Repointing involves removing damaged mortar and replacing it with new mortar. Tuckpointing is a specialized technique that uses two colors of mortar to create the illusion of very fine joints, often used in historic restoration.
4.2 Brick replacement
When individual bricks are severely damaged, they may need to be carefully removed and replaced with matching bricks. This process requires skill to ensure proper bonding and alignment.
4.3 Crack injection and sealing
For smaller cracks, epoxy or polyurethane injection can be used to seal the gap and prevent water infiltration. This method is less invasive than brick replacement.
4.4 Waterproofing and sealants
Applying water repellents or sealants can help protect brick surfaces from moisture damage. However, it’s crucial to use breathable products that allow moisture to escape from the bricks.
5. Choosing the Right Materials for Commercial Brick Repair
5.1 Matching existing bricks
When replacing bricks, it’s essential to match the size, color, and texture of the existing bricks. This may involve sourcing from salvage yards or custom-ordering from manufacturers.
5.2 Selecting appropriate mortar
The mortar used in repairs should match the strength and composition of the original mortar. Using mortar that’s too hard can cause damage to softer, older bricks.
5.3 Sealants and waterproofing products
Choose high-quality, breathable sealants that are appropriate for your specific brick type and environmental conditions. Silane and siloxane-based products are often recommended for their effectiveness and longevity.
6. The Commercial Brick Repair Process
6.1 Planning and preparation
A successful repair project starts with thorough planning:
- Assess the extent of damage
- Determine the appropriate repair methods

While specific steps may vary depending on the repair type, a general process includes:
- Remove damaged bricks or mortar
- Clean the area thoroughly
- Prepare new materials (mix mortar, cut replacement bricks)
- Install new bricks or repoint mortar joints
- Allow proper curing time
- Apply sealants or waterproofing as needed
6.4 Clean-up and finishing touches
After repairs are complete:
- Clean excess mortar from brick surfaces
- Dispose of debris properly
- Conduct a final inspection to ensure quality
7. Preventive Maintenance for Commercial Brick Structures
7.1 Regular inspections
Schedule annual inspections of your brick structure, ideally in spring and fall. Look for signs of new damage or worsening of existing issues.
7.2 Cleaning and sealing
Gentle cleaning of brick surfaces can prevent the buildup of dirt and pollutants that can contribute to deterioration. Reapply sealants as recommended by the manufacturer, typically every 5-10 years.
7.3 Addressing minor issues promptly
Don’t wait for small problems to become big ones. Address minor repairs, such as small cracks or loose mortar, as soon as they’re noticed.
