Basements

Basement renovations

Underpinning, waterproofing and finished living space, engineered from the foundation up.

Overview

More living space, built on a sound foundation

Lowering a basement floor or adding a walkout changes the foundation, so the engineering comes first. We design the underpinning for your foundation and soil, specify waterproofing and drainage, and then build the finished space.

What we do

Underpinning and basement lowering

Underpinning is designed around your foundation wall type and the soil bearing capacity, and carried out in sequence to keep the building stable.

If you are weighing options, our article on benching versus underpinning compares the two methods.

  • Underpinning and basement lowering
  • Walkouts and new window openings
  • Waterproofing and drainage
  • Finished living space and secondary suites

FAQ

Common questions

Can't find your answer? Ask us.

Do I need an engineer to lower my basement?

Yes. Underpinning changes the foundation, so municipalities require engineered drawings. We prepare them and handle the permit documentation.

What is the difference between benching and underpinning?

Benching extends the footing to add headroom without fully replacing it; underpinning deepens the foundation. Our article compares them.

Can you add a secondary suite?

Yes. We review zoning and Building Code requirements and prepare the drawings.
