What is basement underpinning?

Basement Underpinning involves strengthening and reinforcing the current foundation of your home. The process is very versatile with numerous advantages for your home. Basement underpinning is used to add extra depth space to the basement by digging under the foundation, creating a firm support level, and then adding concrete sections to reinforce the foundation.

Most commonly, Toronto homeowners choose basement underpinning to increase the ceiling height and area of the basement or crawlspace in their home. However, basement underpinning can also improve the structural integrity of your home’s foundation. The team at Waterproofing PD have the skills and experience to complete the basement underpinning required for your basement visions to come to life.

Why Basement Underpinning?

Simply put, basement underpinning adds space and height to your basement, fixes foundation issues and adds structural strength and stability to your home. These improvements increase the overall value of your home, making it more user friendly and attractive.

Read below for a comprehensive list of the advantages and benefits of basement underpinning:

Create Additional Useable Space

The process of basement underpinning allows for the increase of the height of the structure and adding extra space in the basement to be used for storage, game rooms, bedrooms, offices…whatever you are dreaming of!

Increase Foundation Strength

For foundations that were poorly constructed to begin with, or ones that have suffered significant damage over the years, basement underpinning can be completed to create a more stable foundation. This type of reinforcement can help maintain the structural reliability when adding a second floor to your house, as the foundation will be equipped to carry the extra load.

Fix Foundation Issues

Older homes are particularly susceptible to problems arising because of sliding soil or inadequate foundation installation techniques. If any damage occurs to the foundation, the structural integrity of the entire home is at risk. With basement underpinning, these issues can be fixed, and the structural stability of the foundation renewed.

Opportunity to Improve Waterproofing Measures

The basement underpinning process also provides the perfect opportunity to complete full exterior basement waterproofing as well as ensure that any foundation cracks are repaired and sealed.
