Underpinning vs. Benching: When and Why You Need It

underpinning VS benching

Your basement holds untapped potential. Whether you’re looking to create additional living space, increase the value of your home, or address structural concerns, underpinning and benching are two basement renovation methods that can help you achieve your goals. In this article, we’ll explore the different reasons why you might need underpinning or benching for your basement project.


Reasons for Underpinning

Maximizing Space

Toronto homeowners often choose underpinning when they want to maximize their basement’s space potential. Underpinning allows for significant vertical expansion, creating more headroom and additional square footage. This is especially valuable in neighborhoods with limited above-ground space.

Foundation Repair

If your home’s foundation is showing signs of deterioration, such as cracks, settling, or shifting, underpinning can provide a solution. It reinforces and stabilizes the existing foundation, preventing further damage.

Creating a Legal Basement Apartment

In the Toronto area, basement apartments are subject to specific regulations. Underpinning can help you meet the legal requirements for ceiling height, ventilation, and egress, allowing you to convert your basement into a legal rental unit.

Enhancing Property Value

A well-executed underpinning project can significantly increase your property’s market value. In Toronto’s competitive real estate market, this can be a strategic investment for future resale.

Historic Homes

Many homes in Toronto are heritage properties with unique challenges. Underpinning is often necessary to address structural issues while preserving the historical character of the building.


Reasons for Benching

Limited Depth

Toronto’s dense urban environment can pose challenges for deep excavations. Benching, or underpinning with a “bench,” is a practical solution when there are restrictions on how deep you can dig due to soil conditions, utilities, or neighboring structures.


Benching can be a cost-effective alternative to full-depth underpinning. It allows you to maximize your existing basement’s footprint without the added expense of significantly increasing the depth.

Efficient Use of Space

If your primary goal is to create additional usable space within the existing footprint of your basement, benching provides a functional shelf-like extension that can be used for storage or other purposes.

Renovations and Updates

Homeowners looking to modernize their basement without extensive excavation often opt for benching. It allows for renovations that enhance the aesthetics and functionality of the existing space.


Consult with a Professional

Deciding whether underpinning or benching is the right choice for your basement project is a decision best made with the guidance of a professional substructure contractor. They can assess your specific needs, examine your property’s conditions, and provide tailored recommendations.

Underpinning and benching offer versatile solutions to transform your basement into a valuable and functional part of your home. Whether you’re looking to maximize space, address foundation issues, or enhance property value, these methods can help you unlock your basement’s full potential.

Remember that a well-executed basement project not only improves your quality of life but also adds value to your home, making it a worthwhile investment.
