Structural foundation reinforcement and waterproofing solution for basement expansion and strengthening.
Bench footing is a foundation reinforcement technique where a new concrete footing is poured alongside and below the existing foundation wall, creating an L-shaped ledge (the "bench") that deepens and strengthens the foundation without the full excavation required for traditional underpinning. It is commonly used in Toronto when homeowners want to lower the basement floor by a moderate amount — typically 12 to 24 inches — or when the existing footing needs structural reinforcement but full underpinning isn't warranted.
The technique works by transferring the building's load to a wider, deeper base. The new concrete bench bonds to the existing foundation wall and extends the footing downward, reaching more stable soil and providing additional bearing area. For Toronto homes with shallow original footings that have begun to settle or shift, bench footing restores structural stability without the complexity and cost of section-by-section underpinning.
Why Choose Us
The key difference between bench footing and full underpinning is the depth of floor lowering achieved. Full underpinning can add 2-4 feet of ceiling height by excavating entirely beneath the existing footing. Bench footing typically adds 12-24 inches by building out from the base of the wall rather than going completely under it. This makes bench footing the right choice when you need a moderate height increase — enough to bring a 6.5-foot basement up to 7.5 or 8 feet — without the full scope and cost of underpinning.
Bench footing is also the preferred approach when only one or two walls need reinforcement rather than the entire perimeter. If a single wall is showing signs of settlement — visible cracking, inward lean, or a widening gap between the wall and floor — a bench footing on that wall alone can stabilize the foundation at a fraction of the cost of a full perimeter project. We perform bench footing on individual walls regularly in older Toronto homes where one side of the foundation bears more load or sits on less stable soil.
Don't Ignore the Signs
The bench footing process starts with excavating along the interior side of the foundation wall, digging below the existing footing to the designed depth. Steel reinforcement bars (rebar) are drilled into the existing foundation wall and footing to create a mechanical bond between old and new concrete. The rebar extends into the new footing form, and concrete is poured to create the bench. After curing, the new bench is structurally integrated with the original foundation, effectively making the wall thicker and deeper.
Waterproofing is integrated into every bench footing project we perform. The newly exposed wall surface and the bench itself are coated with waterproof membrane before the floor slab is poured. This is the ideal time to add waterproofing because the wall is already exposed — doing it later would require breaking up the new floor. We also install interior weeping tile along the bench with a connection to the sump system, providing drainage protection for the deepened foundation.
Bench footing requires a structural engineer's involvement for design and a building permit from the City of Toronto when the floor is being lowered. The engineer specifies the bench dimensions, reinforcement spacing, and concrete strength based on your foundation's existing condition and the loads it carries. We work with structural engineers experienced in Toronto residential foundation work who understand the local clay soil conditions and their implications for footing design.
Project timelines for bench footing are shorter than full underpinning — typically 2-4 weeks for a full perimeter and 1-2 weeks for individual walls. Costs are also lower, making bench footing an accessible option for homeowners who want structural improvement and some additional height without a major renovation budget. Every bench footing project includes a 25-year structural warranty and the waterproofing membrane is covered under our standard waterproofing warranty.
Materials & Methods
An L-shaped concrete footing poured alongside the existing foundation wall with rebar drilled into the original concrete for structural integration. Creates a wider, deeper bearing surface.
Holes are drilled into the existing foundation wall and footing, and steel rebar is epoxied into place. The rebar extends into the new bench, creating a permanent mechanical bond.
Waterproof membrane and interior weeping tile are installed during construction while the wall is exposed, providing moisture protection for the deepened foundation.
Our Process
A structural engineer evaluates your foundation, designs the bench dimensions, and specifies reinforcement requirements based on soil conditions and building loads.
We obtain the required building permit from the City of Toronto and coordinate the construction schedule with inspections.
The interior is excavated along the wall to below the existing footing. Rebar is drilled into the existing foundation to mechanically bond old and new concrete.
The bench footing is formed and poured with reinforced concrete. Curing time is observed before proceeding to waterproofing and floor restoration.
Waterproof membrane is applied to the bench and exposed wall, interior weeping tile is installed, and the new floor slab is poured at the lower level.
Client Reviews
“Outstanding job! My basement is finally dry thanks to your team. No more musty smell or moisture problems. A+ service!”
“From the initial appointment to final inspection, service was exceptional. Prompt, professional, and results exceeded expectations.”
“Professional and friendly staff. They solved our leaky basement in no time. The results were fantastic. Basement has been leak-free since the work was done.”
