Underpinning was done at a Downtown, Toronto home near the Spadina Rd and Dupont St area. The customer was looking to expand their basement through the underpinning process to increase the amount of living space they could have. The first step was benching to strengthen the basement foundation walls to support the structure. Next, the basement floor was dug down to the foundation footings creating higher ceilings and open up the living space. The last step was to do a full interior waterproofing by adding a new drainage system and waterproofing membrane.
