What is Underpinning? Underpinning is the process for lowering your basement floor. In underpinning a sequence of holes are dug from under the footing of your home and filled with concrete to extend the footing of your house to a lower level. This allows us to dig the soil out from the inside of the basement without undermining the foundation of your home, resulting in a higher basement ceiling.


Waterproofing is required by building codes on structures that are built at or below the ground level. OnlyBasements has extensive experience in both underpinning and waterproofing performed in variety of homes in The Beaches, Leslieville and East York neighbourhoods.
