The Basement Underpinning Process

What is Basement Underpinning in Toronto?

Basement underpinning is a structural process that strengthens and extends your existing foundation walls downward by excavating beneath the current foundation in sections. This method involves digging around and under your foundation walls, then pouring new concrete to create a deeper, stronger foundation.

How Underpinning Works to Increase Basement Height

  1. Excavation beneath existing foundation walls in alternating sections
  2. Installation of temporary structural support systems
  3. Pouring new concrete foundation walls at a deeper level
  4. Backfilling and waterproofing the expanded foundation

Underpinning Benefits

  • Maximum ceiling height increase – typically adds 2-4 feet of headroom
  • Full basement floor space retained – no reduction in usable square footage
  • Strengthens foundation – improves structural integrity of your Toronto home
  • Highest property value increase – provides maximum return on investment
  • Allows for modern amenities – creates space for full-height basement apartments

Why Choose Benching

What is Bench Footing?

Bench footing creates a stepped or "bench-like" concrete structure around your basement's perimeter while leaving the original foundation walls intact. This method builds a new foundation wall inside your existing basement, creating additional structural support.

How Professional
Bench Footing Works

  1. Excavation around the perimeter of the basement (typically 18-24 inches from the walls)
  2. Installation of new concrete footings at a lower level
  3. Construction of new foundation walls creating a “bench” appearance
  4. Waterproofing and finishing the new concrete surfaces

Bench Footing
Benefits

  • Cost-effective solution – typically 30-40% less expensive than traditional underpinning
  • Faster installation – usually completed in 2-3 weeks vs. 4-6 weeks for underpinning
  • Structural reinforcement – adds significant foundation strength
  • Less disruptive – requires less excavation than full underpinning
  • Good for moderate height increases – typically adds 12-24 inches of ceiling height

How Basement Lowering Works for a
Complete Basement Transformation

What is Basement Lowering?

Basement lowering involves excavating your existing basement floor to increase ceiling height without altering the foundation walls. This method requires careful engineering to ensure the foundation walls remain properly supported during and after the floor excavation.

How We Lower Your Basement

  • Assessment of existing foundation depth and stability
  • Excavation of the basement floor to the desired depth
  • Installation of new drainage systems and vapour barriers
  • Pouring of a new concrete floor at the lower level
  • Waterproofing and finishing work

Basement Lowering Benefits for Homeowners

  • Preserves existing foundation – works with structurally sound foundation walls
  • Moderate cost option – typically falls between benching and underpinning costs
  • Effective height increase – can add 18-36 inches of ceiling height
  • Maintains full floor space – no reduction in usable basement area
  • Integrates modern systems – opportunity to upgrade plumbing and electrical

Which Method is Right for Transforming Your Basement in Toronto?

We recommend choosing underpinning if:

  • You want maximum ceiling height for a legal basement apartment
  • Your foundation needs structural reinforcement
  • You’re planning extensive basement renovations
  • Property value increase is a primary goal

 

We recommend choosing bench footing if:

  • Budget is a primary concern
  • You need a moderate height increase for basic functionality
  • Your timeline is limited
  • You don’t mind losing some floor space around the perimeter

 

We recommend choosing basement lowering if:

  • Your existing foundation walls are structurally sound
  • You want to preserve the original foundation elements
  • You need a moderate height increase without major structural changes
  • You’re dealing with a heritage home where foundation preservation is important

Our Contractors Understand Toronto's Unique Conditions

Toronto-Specific Considerations

Toronto's unique housing stock and soil conditions affect method selection:

  • Century homes in established neighbourhoods often benefit from underpinning due to aging foundation materials.
  • Post-war homes in East York and Scarborough may be ideal candidates for bench footing.
  • Clay soil areas throughout Toronto require enhanced waterproofing, regardless of the method chosen.
  • Homes near ravines or Lake Ontario may need specialized drainage solutions
 

All three methods require Toronto building permits and professional engineering approval. The choice often depends on your specific foundation condition, budget, intended use, and timeline requirements.

I contacted TTA and within a day they arrived to provide an estimate (not gouging which I had with other companies when they provided costs). My job was a small concrete job leading into my garage to remove asphalt and replace with concrete etc. Teo has been available for communication during the whole process which for someone that isn’t handy made me feel more confident. The whole project from initial reach out to completion took less then a week and they have been professional and honest with me.
