12 Common Problems to Look Out for During a Brick Wall Installation by Maçonnerie Montréal


Brick wall installations are known for their durability, aesthetics, and overall appeal. However, even the most skilled masonry contractors can encounter challenges during the installation process. In this article, we will explore 12 common problems to look out for during a brick wall installation, as well as how to address them effectively.

Common Problems in Brick Wall Installations

1. Inadequate Site Preparation

Poor site preparation can lead to an unstable foundation, resulting in a weakened brick wall. To prevent this, ensure that the site is properly cleared, leveled, and prepared for the foundation.

2. Incorrect Mortar Mix

Using the wrong mortar mix can cause issues with the bond between bricks and mortar, leading to weak joints. Always use the correct mortar mix for the specific brick type and project requirements.

3. Inconsistent Mortar Joint Thickness

Inconsistent joint thickness can result in an uneven and unstable brick wall. To avoid this, maintain a consistent joint thickness throughout the installation process.

4. Poor Brick Alignment

Misaligned bricks can compromise the structural integrity of the wall and detract from its appearance. Use a level and a string line to ensure bricks are properly aligned during installation.

1.5. Insufficient Curing Time

Failing to allow the mortar to cure properly can cause premature cracking or crumbling. Follow the manufacturer's recommendations for curing time and keep the mortar damp during this period.

6. Inadequate Wall Ties

Wall ties are essential for connecting the brick veneer to the structural wall. Insufficient or poorly installed wall ties can lead to wall separation and instability. Ensure wall ties are properly spaced and installed according to the building code.

7. Improper Flashing Installation

Incorrectly installed or missing flashing can lead to water infiltration and damage. Install flashing at all necessary locations, such as above windows and doors, and ensure proper overlap and sealing.

8. Insufficient Expansion Joints

Lack of expansion joints can cause brick walls to crack due to thermal expansion and contraction. Plan for adequate expansion joints and install them at the recommended intervals.

9. Inadequate Weep Holes

Weep holes help to release moisture from behind the brick wall. Failing to include weep holes or improperly spacing them can result in moisture buildup and potential damage. Install weep holes at the base of the wall and above flashing.

10. Poorly Installed Damp-Proof Course (DPC)

A DPC prevents moisture from the ground from rising into the brick wall. If not installed properly, moisture can penetrate the wall, causing damage. Ensure the DPC is continuous, level, and installed at the correct height.

11. Inappropriate Brick Selection

Choosing the wrong type of brick can lead to problems with durability and appearance. Always select bricks appropriate for the specific project and climate conditions.

12. Rushed Construction

Rushing the construction process can result in a poorly built brick wall. Allow adequate time for each stage of the installation to ensure a high-quality final product.


Brick wall installations can be a beautiful and durable addition to any property, but they are not without potential challenges. By being aware of these common problems and taking the necessary precautions, you can ensure a successful and long-lasting brick wall installation.
