 Basement Underpinning & Lowering in Toronto

 What is Basement Underpinning?

Underpinning involves extending your foundation downward to increase ceiling height and reinforce structural integrity. It’s the most effective solution for converting low-ceiling basements into full-height, usable living space.

 Other Basement Lowering Options

Bench Footing

A cost-effective alternative to full underpinning. We excavate inside your foundation walls and pour a concrete bench along the perimeter. It’s quicker and cheaper, but reduces usable floor space slightly.

Slab Lowering

In select cases, we can lower the concrete floor without touching the foundation — ideal for homes with enough structural clearance.

 Benefits of Lowering Your Basement

  •  Create livable square footage with full-height ceilings

  •  Add value to your home

  •  Build legal basement apartments or rental units

  •  Add bedrooms, bathrooms, laundry, or rec space

  •  Improve waterproofing, sump pumps, and drainage
