Are you considering renovating your basement or adding some extra space to your home? If so, basement underpinning could be a great option for you. Basement underpinning involves extending the height or depth of your basement foundation to create more living space. However, it’s important to understand what it entails, how it works, and what you should consider before undertaking this process. This article provides everything you need to know about basement underpinning in Toronto in 2023.

What is Basement Underpinning?

Basement underpinning is the process of strengthening an existing basement foundation by extending it downwards. It involves excavating the soil beneath the foundation and pouring new concrete footings to increase the depth of the foundation. This provides additional headroom in the basement, making it a usable space. Basement underpinning is a common solution for homeowners who need more space but don’t want to move.

Why Should You Consider Basement Underpinning?

There are many benefits to underpinning your basement. First and foremost, it can increase your living space, adding value to your home. It also allows for the installation of new plumbing and electrical systems, and can reduce the need for additional supports, such as columns or beams. Additionally, underpinning can increase the overall stability of your home’s foundation, making it less susceptible to damage from soil erosion, water damage, and other environmental factors.

How Does Basement Underpinning Work?

The process of underpinning your basement involves several steps. First, your home will be inspected to determine if underpinning is a viable option. Then, the excavation process will begin, and the soil will be removed from beneath the foundation in small sections. The new concrete footings will be poured in stages, allowing time for the concrete to cure between each pour. Once the footings are complete, the existing foundation walls will be lowered to rest on the new footings. Finally, the space between the old and new foundation walls will be filled with concrete to create a solid, stable foundation.

What are the Benefits of Basement Underpinning?

Underpinning your basement can provide numerous benefits, including:

  • Increased living space
