Underpinning also helps fix other issues, like:
• Stopping leaks and water damage
• Making your home stronger and safer
• Saving energy by sealing cracks and adding better insulation

Why Do Basement Underpinning?

FAQ

Underpinning is the process of making your home’s foundation stronger and deeper. It’s often done to make basement ceilings higher and to support the structure of the house.

Many older homes in Toronto have low basements that aren’t very useful for living space. Underpinning can fix that.

With underpinning, you can:

  • Make your basement taller and more comfortable to use

  • Get your home ready for adding extra floors or making big changes

  • Make your home stronger and increase its value

UNDERPINNING

The first step in underpinning involves excavating the soil beneath the existing foundation. This is typically done in sections to ensure that there is sufficient support for the structure during the process. Careful excavation is essential to maintain the stability and integrity of the building above.

1. Digging Section by Section:

After the excavation, the next step is to form and pour concrete to create a new foundation under the existing one. Steel reinforcement may be added to enhance the strength and stability of the new foundation. This concrete underpinning provides additional support for the structure and helps redistribute the load to the deeper layers of soil.

2. Forming and Pouring Concrete:

Once the new foundation is in place, the ground level can be lowered to increase the height of the basement ceiling.
