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, increasing the ceiling height of your basement.


Waterproofing is a building code requirement for structures that are built at or below the ground level. onlyBASMENTS has extensive experience in both underpinning and waterproofing performed in older homes of Toronto.
