Overview of basement lowering and underpinning

Basement lowering and underpinning is a complex yet essential method used to create more usable space in basements, often in older Toronto homes. This process involves excavating the existing basement and either levelling or raising it to create additional space. It can also involve reinforcing foundation walls with new material if needed. In most cases, waterproofing is needed along with a reliable support system for the surrounding soil. With this method, additional living space for bedrooms, bathrooms, rec rooms, family rooms, etc., can be added to an older home without compromising the structural integrity of the property itself. Therefore, basement lowering and underpinning can be an incredibly beneficial solution for Toronto homeowners who are looking to improve their basement areas and add extra value to their properties.
