Cracks in brick walls can raise numerous concerns for homeowners. Are they structural or non-structural? What is the severity level of each crack? In this comprehensive guide, we'll provide you with detailed answers and essential information to help you understand how to differentiate between structural and non-structural cracks in a brick wall. At Masonry Montreal, we are committed to equipping you with the knowledge you need to make informed decisions regarding the repair of your brick wall.
Understanding Non-Structural Cracks
Non-structural cracks, also known as cosmetic cracks, are generally less worrisome from a structural standpoint. They are primarily related to aesthetic or climatic factors. Here are some characteristics of non-structural cracks:
- Thinness: Non-structural cracks are often thin, typically not exceeding 1/8 of an inch (about 3 mm) in width.
- Direction: They can appear vertically, horizontally, or diagonally, without following a specific path.
- Location: They usually occur on the surface of the brick wall, without penetrating deep into the masonry.
- Possible Causes: Non-structural cracks are often the result of temperature changes, minor soil movements, or the normal expansion and contraction of materials.
Identifying Structural Cracks
Conversely, structural cracks are more concerning as they indicate potential issues with the stability of the structure. It is essential to be able to distinguish them correctly. Here are some characteristics of structural cracks:
- Width: Structural cracks are generally wider, often exceeding 1/8 of an inch (about 3 mm), and can even widen over time.
- Orientation: They often follow a specific trajectory, such as horizontal, vertical, or step-like cracks.
- Depth: These cracks can penetrate deep into the masonry and affect the overall stability of the wall.
- Possible Causes: Structural cracks can result from foundation problems, soil movements, excessive loads, or the corrosion of metal reinforcements.
The Importance of Professional Assessment
Differentiating a structural crack from a non-structural one can be complex for a non-professional. That's why it's essential to rely on masonry experts like Masonry Montreal. Our experienced professionals have the knowledge and expertise needed to accurately assess the condition of your brick walls and recommend appropriate measures.
Steps to Follow
When you observe cracks in your brick wall, follow these steps to determine their nature and severity:
Step 1: Examine Width and Direction:
- Measure the width of the crack using a caliper or ruler.
- Note the direction of the crack, whether it's horizontal, vertical, or diagonal.
Step 2: Assess Depth:
- Try to determine how deep the crack extends into the masonry. A shallow crack is more likely to be non-structural.
Step 3: Consider Circumstances:
- Take into account the circumstances surrounding the appearance of the cracks. For instance, cracks that occur after an earthquake or flood are more likely to be structural.
Step 4: Seek Professional Assistance:
- If in doubt or if you suspect a structural crack, contact Masonry Montreal for a professional assessment.
