Excavation Shoring in Vaughan, ON | OCM Excavation
OCM Excavation installs engineered shoring on deep excavations across Vaughan — Woodbridge, Maple, Thornhill, Kleinburg, and Concord. Many Vaughan projects are newer subdivisions where the original foundation went in clean, but new backyard utility upgrades, pool builds, additions, and basement lowering jobs now need shoring once the dig passes the 1.2-metre Ontario threshold. We run hydraulic shores, steel trench boxes, and soldier pile systems sized to Vaughan’s clay and clay-till profile. For a same-week site visit, call 416-317-3090.
Where Shoring Shows Up on Vaughan Projects
The most common shoring call in Vaughan is a backyard utility upgrade — a homeowner running a new gas line to a pool heater, replacing a failed weeping tile, or installing a storm connection for a graded backyard renovation. Those trenches push past 1.2 metres fast, and Ontario Regulation 213/91 makes the support system mandatory. Steel trench boxes are the go-to here because they let two workers move along a long trench safely.
The other big driver is deeper foundation work: lowering a Vaughan basement for headroom, adding a legal second suite, or building an addition that lands tight against the existing foundation. Those move into hydraulic shores at moderate depth and soldier pile with lagging on deep or lot-line digs.
Shoring Methods We Use in Vaughan
- Steel trench boxes — the workhorse for Vaughan backyard utility runs and longer trenches where workers walk the full length.
- Hydraulic trench shores — fast install at residential depths between 1.2 and 3 metres, ideal for foundation repair pits and shorter sewer trenches.
- Soldier pile and lagging — deep basement excavations and lot-line digs where the wall sits within a metre or two of an existing structure.
- Slide rail systems — wider parallel-utility trenches and projects where standard shore widths don’t fit.
Our Yanmar SV40 mini excavator handles the placement of standard hydraulic shores in tight Vaughan backyards where a full-size excavator would tear up the lawn or never make it through the side gate.
Engineering and Permits in Vaughan
Vaughan building permits are issued through the City’s Building Standards Department. For most foundation, addition, and basement lowering projects, the shoring drawings are submitted with the foundation package rather than as a separate permit. Excavations beyond roughly 3 metres of depth, and any system that supports a neighbouring foundation, require sealed drawings from a Professional Engineer in Ontario. We coordinate that engineering directly so it isn’t a separate hunt for the homeowner.
Typical Cost Range
Most residential shoring jobs in Vaughan come in between $8,000 and $50,000. A short trench-boxed gas or water trench in a backyard sits near the low end. A soldier pile system carrying a deep basement excavation beside an existing structure, with engineering and monitoring, reaches the upper end on larger lots. Depth, soil class, water table, and proximity to adjacent structures move the number more than the neighbourhood does.
Why Vaughan Owners Hire OCM
We own our excavators, trench boxes, and hydraulic shores. That means we don’t pad Vaughan shoring quotes with daily rental markups, and we can hold a tight schedule when a foundation surprise pushes a project sideways. We’re fully insured under our commercial liability policy and we don’t put a crew in a trench over 1.2 metres without a compliant support system. For a Vaughan estimate, call 416-317-3090.

Frequently Asked Questions
Does a backyard gas line trench in Vaughan need shoring?
If the trench goes past 1.2 metres in Vaughan’s typical clay-till soil and a worker has to enter it, yes. Ontario Regulation 213/91 doesn’t carve out backyard utility work. Steel trench boxes are the usual answer because they slide along as the line is installed, keeping the workspace compliant without slowing the crew down.
Can shoring be installed without removing my fence?
Usually yes, when the access point is a standard 1.2-metre side gate. Our Yanmar SV40 mini excavator places hydraulic shores and lifts trench boxes within that footprint. Tight backyards with no side access can still be done, but a fence panel sometimes comes out and goes back — we quote that up front.
How long does a Vaughan shoring job take?
Standard trench-boxed utility work moves at the pace of the utility install — typically one to three days on site. Hydraulic-shored foundation pits are usually one to two weeks. Engineered soldier pile systems for full basement excavations run two to six weeks depending on depth and lot-line conditions.
Do I need to notify the Ministry of Labour?
Notice of Project filings are required for excavations meeting the thresholds in Ontario Regulation 213/91. For most residential Vaughan shoring jobs that involve deep digs or workers entering trenches, a Notice of Project applies. We file it on our jobs as the constructor responsible for the excavation.
What happens if my contractor skips shoring?
A Ministry of Labour inspector can issue a stop-work order on the spot, and you as the homeowner can be exposed to liability if a worker is injured in an unshored trench on your property. Cost savings from skipping shoring are real but tiny compared to the downside. The right move is a clean quote that prices shoring openly.
