If you’re a homeowner in Toronto, you may find yourself faced with the decision between bench footing and underpinning when it comes to foundation reinforcement or basement lowering projects. Understanding the differences between these two methods is essential for making the right choice for your home. In this comprehensive guide, we will delve into the intricacies of bench footing vs. underpinning in Toronto, exploring their unique applications, benefits, and costs. With this information at your fingertips, you’ll be better equipped to make an informed decision and ensure the structural integrity of your home for years to come.
Bench footing is a specialized method used for lowering basement floors. It’s an excellent option for homeowners looking to gain extra living space in their basements without impacting the foundation walls.
Bench footing is a unique method of reinforcing a foundation that involves constructing a new footing alongside the existing foundation footing. This process is carried out with careful excavation to ensure the angle of repose of the original foundation is not compromised. Typically, the deeper the bench footing goes, the more it extends into the basement area. By utilizing this method, homeowners can effectively lower their basement floors while maintaining the structural integrity of their home’s foundation and avoiding potential issues that could arise from more invasive techniques such as underpinning.
Foundation underpinning is another method used for basement lowering and reinforcement. Unlike bench footing, underpinning focuses on strengthening the existing foundation walls by extending their depth or breadth.

There are several types of underpinning techniques utilized by construction professionals in Ontario to address various foundation issues. Each method offers unique advantages and is suited to specific situations. Here are three popular types of underpinning:
The non-shrink method of underpinning is a reliable technique used to reinforce and stabilize the foundations of buildings. This process involves the careful excavation of soil beneath the foundation footing, followed by the pouring of an underpinning section with the full width of the footing. A 2-inch gap is intentionally left between the original footing and the new underpinning to accommodate the application of non-shrink grout. The use of non-shrink grout is crucial, as it helps minimize concrete shrinkage and ensures seamless integration with the existing structure. By combining the stability of concrete with the flexibility of non-shrink grout, this method provides a robust and long-lasting solution for foundation reinforcement in various types of buildings across Ontario.
The overpour method is another effective underpinning technique used to enhance the structural integrity of buildings. This method involves excavating the soil beneath the foundation footing and partially removing the foundation footing itself. Once completed, concrete is poured to create an underpinning section that fully overlaps with the foundation wall. To ensure minimal concrete shrinkage and optimal bonding with the existing structure, a vibrator is used during the pouring process. By overlapping the new underpinning section with the foundation wall, this method provides superior load transfer and improved structural support, making it a popular choice for reinforcing the foundations of buildings throughout Ontario.
The flush-with-the-wall method of underpinning is employed to deliver superior structural support and reinforcement for buildings with varying foundation requirements. This method entails excavating the soil under the foundation footing and partially removing the foundation footing itself. The concrete underpinning section is then poured flush with the foundation wall, creating an L-shaped structure that expands at the bottom to match the footprint of the foundation footing. To ensure maximum strength and durability, the underpinning section is reinforced with 15 mil metal rebars and metal rebar anchors that secure it to the foundation wall. The use of a vibrator during the pouring process is essential for minimizing concrete shrinkage and achieving a solid connection between the new underpinning section and the existing structure. With its robust design and exceptional load-bearing capacity, the flush-with-the-wall method is a proven technique for reinforcing foundations in a wide range of building projects across Ontario.
Both bench footing and underpinning have their advantages and disadvantages. Bench footing can lower basement floors with less impact on the foundation walls while underpinning is better suited for reinforcing existing walls. However, bench footing may require more extensive support during the process.
When considering the costs of bench footing and underpinning for your home, it is essential to note the differences in pricing for each method. As of 2023, the approximate cost for bench footing is around $300 CAD per linear foot, while underpinning is priced at around $420 CAD per linear foot of the foundation wall. These prices may vary depending on factors such as the complexity of the project, the specific requirements of your home, and any additional work needed to ensure a successful outcome. It is crucial to carefully evaluate the costs and benefits of each method, taking into account your unique circumstances and project goals, to determine the most cost effective and suitable solution for your home’s foundation reinforcement or basement lowering project.
Bench footing is often used in situations where the underpinning method is not feasible or practical. For instance, in a semi-detached building with a common wall, bench footing may be the preferred choice when neighbours do not grant permission to underpin the shared wall. Another scenario where bench footing might be more suitable is when a detached building is too close to the underpinning foundation, and there is a risk of undermining the angle of repose. In such cases, bench footing offers an alternative solution for stabilizing and reinforcing the foundation without the need for underpinning, allowing homeowners to proceed with their basement lowering or foundation reinforcement projects without compromising the structural integrity of their homes or neighbouring properties.
The underpinning method is a popular choice among Toronto homeowners when it comes to lowering the basement floor and maximizing the basement area.
