Installing a Brick Wall on an Existing Concrete Foundation: A Comprehensive Guide by Maçonnerie Montréal


When it comes to masonry projects in Montreal, many homeowners and business owners wonder if they can install a brick wall on an existing concrete foundation. In this comprehensive guide we will explore the feasibility of this process, discuss the necessary preparations, and provide expert advice on how to ensure a successful and durable brick wall installation.

Assessing the Feasibility of Installing a Brick Wall on a Concrete

Foundation Before proceeding with the installation of a brick wall on an existing concrete foundation, it is important to assess the feasibility of the project. Some key factors to consider include:

Structural Integrity

Ensure the existing concrete foundation is in good condition, free of cracks or damage, and capable of supporting the additional weight of the brick wall.


Verify that the concrete foundation is compatible with the brick wall, taking into account factors such as moisture resistance and thermal properties.

Building Codes and Regulations

Consult with local building authorities in Montreal to ensure your proposed brick wall installation meets all necessary codes and regulations.

Preparing the Concrete Foundation for Brick Wall Installation

Once you have determined that your project is feasible, the next step is to prepare the concrete foundation for the brick wall installation. Some crucial steps in this process include:

Cleaning the Surface

Thoroughly clean the concrete foundation, removing any dirt, debris, or old paint to ensure a strong bond between the bricks and the concrete.

Applying a Waterproof Membrane

Install a waterproof membrane to protect the brick wall and concrete foundation from moisture damage, which is especially important in Montreal's climate.

Installing a Brick Ledge

If your concrete foundation lacks a brick ledge, consider adding one to provide additional support for the brick wall.

Installing the Brick Wall on the Concrete Foundation

With the foundation prepared, it is time to proceed with the brick wall installation. Follow these expert tips from Maçonnerie Montréal:

Using the Proper Mortar Mix

Choose a mortar mix that is compatible with both the bricks and the concrete foundation, ensuring a strong bond and a durable installation.

Laying the Bricks

Begin laying the bricks on the concrete foundation, using spacers to maintain a consistent mortar joint thickness and ensure a level installation.

Installing Wall Ties

Use wall ties to secure the brick wall to the concrete foundation, providing additional stability and preventing movement or separation.

Curing the Mortar

Allow the mortar to cure properly, following manufacturer recommendations for optimal strength and longevity.

Hire a professional if needed

If you're unsure of your ability to install the brick wall yourself, don't hesitate to call on a professional and experienced masonry contractor to assist you.


Installing a brick wall on an existing concrete foundation is possible, provided that the foundation is structurally sound and the necessary preparations are made. By following the guidelines outlined in this comprehensive guide from Maçonnerie Montréal, you can achieve a successful and durable brick wall installation that will enhance your property for years to come.
