    What is Bench footing or Benching?

    Benching, or underpinning with a “bench,” involves adding concrete in front of the existing wall, essentially extending the perimeter of the basement horizontally. Although it doesn’t offer the same vertical expansion as underpinning, benching presents its own merits:

    1. Ideal for Depth Restrictions: Benching is suitable when constraints on excavation depth exist, often due to soil conditions, utilities, or other factors.
    2. Cost-Efficiency: Bench underpinning can be a more budget-friendly option compared to full-depth underpinning.
    3. Enhanced Usability: The created bench can serve as functional space for storage or other purposes.
    Note: You should be aware that the size of the benching will depend on the neighboring structures and the soil conditions. However, the building code typically requires a 7:10 ratio—7 inches down for every 10 inches out. In ideal conditions, a 1:1 ratio may be possible.

    What is Underpinning?

    what is underpinning

    Underpinning involves strengthening and extending the foundation of your existing basement by adding concrete beneath the walls, reinforcing and extending the foundation vertically. This comprehensive process yields significant benefits:

    1. Significant Space Addition: Underpinning provides the opportunity to add significant vertical space to your basement, resulting in increased headroom and a more expansive living area below ground.
    2. Structural Enhancement: By reinforcing the foundation, underpinning enhances the overall stability and structural integrity of your property.
    3. Increased Property Value: A deeper basement created through underpinning can substantially enhance your home’s market value, offering a wise long-term investment.

    Why should you Choose Underpinning?

    Underpinning is the preferred choice when:

    • Maximum additional space and depth are desired for the basement.
    • Existing foundation require reinforcement due to age or structural issues.
    • Extensive renovations are planned or a spacious and versatile living area below ground is desired.
    • Budget permits the investment.

    Why should you Choose Benching?

    Benching is a practical choice when:

    • Shallow excavation, makes full-depth underpinning impractical. (below 2 feet)
    • Maximizing existing basement footprint without significant vertical expansion is desired.
    • Budget- or cost-effective means of increasing the basement’s usable space are sought.
    •  Reinforce the footing only, or stop the water, bricks or stone foundations
    • short time line, benching is way stronger and faster process. 

    what you should know

    Benching vs Underpinning

    What is the difference? 

    The primary difference between benching and underpinning lies in their purpose and scope. Benching is typically a preventive or corrective measure to enhance stability, while underpinning is a comprehensive solution to address severe foundation issues. Underpinning can also be used to increase the depth of a foundation to support additional floors or heavier loads. Underpinning in Toronto is quite common due to how older homes were built.

    How much does benching cost?

    In terms of complexity and cost, benching is generally a less intricate and more cost-effective solution. It requires less equipment and labour compared to underpinning, making it a suitable choice for less severe foundation concerns. Usely start around $125 up $500 a foot. 

    How much does underpinning cost?

    Being a more involved process, underpinning has higher costs due to the need for specialized equipment and skilled professionals. Starting at $400 a foot and can go up to $1200 if you dig a crawl space or major structural repair.

    The Space-Maximizing Underpinning is the #1 choice

    While a bench-all-around approach offers cost-effective and efficient use of existing space, underpinning stands out for providing significant vertical expansion. Underpinning creates ample headroom and additional square footage below ground, making it the preferred choice for homeowners looking to maximize their basement's potential.

    Benching, underpinning, or both?

    When deciding between benching and underpinning for your foundation-related project, consider the severity of the foundation issues, the project budget, and the long-term goals. Benching is a practical option for minor stability improvements, while underpinning is the go-to choice for addressing significant foundation problems and supporting structural modifications. Both of these methods will increase living space, but underpinning will give you more usable floor space. Consulting with experienced professionals is crucial to determining the most suitable method based on your specific needs.

    Why we can be the right fit?

    With our expertise and over 20 years of experience, me and my team can help you save money and optimize your space using either a bench-all-around, or underpinning or a hybrid method, or a combination of both in the same project. We work for you and your satisfaction is our ultimate goal.

    Step-by-Step Guide: How to Lower My Basement?

    1. Assessment and Planning: Evaluate the feasibility of the project, sign the agreement, and obtain the necessary permits.

    2. Preparation: Clear out the basement and install temporary support structures.

    3. Excavation: Remove the existing floor and soil from underneath the existing basement floor slab. (expose the footings.)

    4. Benching or Underpinning: Choose between benching or underpinning methods for structural modifications.

    5. Finishing: Install drains and French drain systems, install the waterproofing membrane, finish the basement floor, and add desired utilities and features. (we have a unique way to deal with those.)

    6. Inspection and Approval: Schedule inspections and obtain necessary approvals from local authorities. (all inspections are coordinate by us )

    7. Restoration: Replace furniture, belongings, and utilities to restore the basement to its intended use. Enjoy your new extra living space.

    I hired G1000 Home to install a concrete pad in the backyard for our 8x10 shed. Gemil provided a fair quote, and supervised the job from start to finish, ensuring time lines were met, the site was kept clean and the installation was done properly. Previous clients gave G1000 amazing reviews so I knew we could count on them to execute the job properly, on time and within budget. Gemil is extremely knowledgeable about concrete and strong foundations. I am so extremely happy with the end result and would recommend Gemil and G1000 Home Substructure with confidence and satisfaction!

Consulting with experienced contractors and structural engineers will help determine the feasibility and potential challenges of basement lowering for your specific property.

    Yes, basement lowering projects are subject to local building codes and regulations. These codes dictate aspects such as ceiling height requirements, structural modifications, permits, and safety measures. It is crucial to consult with professionals familiar with the local codes to ensure compliance and obtain the necessary city permits.


    The duration of the basement lowering process depends on various factors, including the size of the basement, complexity of the project, access, and any unforeseen issues encountered during construction. Generally, basement lowering projects can take several weeks to a few months to complete. A detailed timeline can be provided by the contractors after assessing your specific project.
