Full underpinning isn't the only way to lower a basement. Bench footings deliver real ceiling height gain in less time and for 20 to 35 percent less money - the tradeoff is a narrow ledge of floor space along the perimeter. This guide breaks down how the method works, when it's the smarter call, and when it isn't.
How Bench Footings Work
With bench footings, new concrete footings get poured next to your existing foundation footings instead of underneath them. The centre of the floor gets dug down to full target depth, while a concrete ledge - the bench - stays at the original footing height along the perimeter walls. That bench runs 12 to 18 inches wide along each wall, carrying the foundation's load down through the new footing into undisturbed bearing soil.
The tradeoff in one sentence: the centre of your basement gets full ceiling height, while the perimeter sits a step lower where the bench ledge is.
Bench Footings vs. Full Underpinning
Bench Footings
20-35% lower cost, faster timeline, full ceiling height at centre - but a 12-18 inch perimeter bench reduces usable floor width.
Full Underpinning
Higher cost, longer timeline, but retains 100% of your existing floor area with no perimeter step - the better fit for legal suites and narrow layouts.
When Bench Footings Is the Right Choice
Bench footings works well when your basement is wide enough that a 12-18 inch perimeter bench doesn't meaningfully impact your planned floor plan, when full underpinning's cost exceeds your budget, when you're not planning a legal secondary suite (or the suite layout can work around the bench), or when your timeline can't accommodate underpinning's longer sequence. It's a strong fit for a basement finished as a rec room or home office, where perimeter built-ins can conceal the bench ledge entirely.
What Bench Footings Cost in Hamilton
On a comparable home, bench footings typically runs 20 to 35 percent below the cost of full perimeter underpinning - for most local projects that lands between $30,000 and $65,000 all-in, depending on perimeter size, depth, soil, and waterproofing scope. Every BaseWorks proposal includes pricing for both bench footings and full underpinning side by side, so the decision comes down to what's right for your home - not guesswork.

Frequently Asked Questions
The bench runs 12 to 18 inches wide along each perimeter wall. For most basements that's a manageable trade-off, especially where perimeter built-ins or storage can conceal the ledge - but it matters more in narrow townhomes and smaller semis.
It depends on the layout. Because the bench reduces usable width along the perimeter, some floor plans can still meet Ontario Building Code suite dimensions and others can't. If a legal suite is even a future possibility, that should be flagged during the assessment before choosing bench footings over full underpinning.
Yes. Bench footings Hamilton goes through the same engineering and permit rigour as full underpinning - engineer-stamped drawings, a City of Hamilton building permit, and mandatory inspections before each pour. The sequence is faster, not the standard.
