Excavation and grading work we do in Hamilton
We run the machine work that sits under everything else a property needs. As a Hamilton excavation contractor, we handle the digging, moving, and shaping ourselves. Here's the range of excavation in Hamilton we take on:
- Lot and site grading. Shaping and re-grading the ground so water runs where it should and the surface sits the way the build needs it.
- Foundation and footing excavation. Digging out for foundations, additions, and structural footings down to solid, undisturbed ground.
- Trenching for drainage and services. Clean trenches for drainage runs, water, and service lines.
- Weeping-tile and foundation drainage. Excavating around a foundation to lay or replace the drainage that keeps a basement dry.
- Deck and fence footings and post holes. We dig the footings and post holes for our own deck and fence builds, and as a standalone dig too.
- Prep for patios, walkways, and retaining walls. Excavating and grading the base so hardscaping sits level and stays put.
- Demolition, debris and soil removal, and hauling. Tearing out what has to go, then loading and hauling the spoil off-site.
- Final grading. The last pass that leaves the lot shaped, smooth, and draining before sod, stone, or the build goes down.

Locates first: Ontario One Call before we dig
Before a machine touches the ground, we book the locates. In Ontario that isn't optional, under the Ontario Underground Infrastructure Notification System Act, 2012, anyone digging has to request locates through Ontario One Call first, whether it's a single fence-post hole or a full foundation. We submit the request at least five business days ahead, and the utility owners, gas, hydro, water, telecom, come out and mark their buried lines.
The locate is free, and we make the call on every job. Digging without it is an offence under the Act, and it's how an excavator hits a gas line or cuts the hydro to half the street. It's part of why hiring a licensed and insured crew matters on machine work, the standard is built in, not skipped to save a week.
Grading and drainage that move water the right way
Plenty of the calls we get aren't really about digging a hole, they're about water going where it shouldn't. Grading fixes that. The rule is simple: water moves away from the house, never onto the neighbour's land. We grade so the slope carries runoff where it belongs, cut swales where the yard needs a channel, extend downspouts past the foundation, and re-shape the low spots that pond after a storm.
Hamilton ground makes this matter more. Up on the Mountain and toward the brow you're often working heavy clay, and clay holds water, it won't drain on its own, so the grade has to do the work. In the tight older lower-city lots, runoff has nowhere to go but the next yard over if it isn't shaped right. Near the harbour and the North End the ground turns to sandier loam that drains easier but still needs a grade that pulls water off the foundation. We read the soil and the slope before we shape anything.
Permits, the conservation authority, and the escarpment in Hamilton
Plain grading and landscaping usually doesn't need a building permit, but a structural or foundation dig is tied to the permit for whatever you're putting up, and a demolition needs its own. We confirm what's required with the City before we break ground rather than guess.
There's a second layer in Hamilton that catches people: the conservation authority. If the dig is near a watercourse, a floodplain, a wetland, or a steep slope, the Hamilton Conservation Authority (HCA) may require a permit before any site alteration. Under Ontario Regulation 41/24, in force since April 1, 2024, that approval has to come before the ground is touched in a regulated area. We check whether your lot falls in one and confirm with the HCA before we dig.
The escarpment adds one more. The Niagara Escarpment splits the lower city from the Mountain, and lots designated as escarpment land near the brow can also fall under the Niagara Escarpment Plan, another approval on top of the city and the conservation authority. If you're on escarpment-protected ground, that's something we help you check before the job starts, not after.
Machine work that fits a Hamilton lot
Not every Hamilton property gives a machine the same room, and the access decides half the job. The tight century-home lots in Durand and Corktown are the hard ones, narrow side yards, mature trees, and neighbours a few feet off the line, with the only way in sometimes a gate barely wide enough. We plan the approach so the machine gets where it needs to be without tearing up what's staying.
The newer Mountain subdivisions are the other end of it, more open, easier to get equipment in and stage the spoil. Escarpment-edge lots bring their own surprise: shallow soil over rock, where a straightforward dig hits stone sooner than expected. We size the approach to the lot you've got, and at The Hammer Construction we do the digging ourselves, one crew responsible for the ground, the access, and the cleanup.
What working with us looks like
Here's how an excavation job runs with our crew:
- Free site visit and quote. Send your details through the contact form, or call or text (647) 424-1148. We come out, look at the access and the ground, and give you an honest quote.
- Locates. We book Ontario One Call and wait for the utilities to mark their lines before anything moves.
- Dig. We excavate to the depth and lines the job needs, on undisturbed ground where footings are involved.
- Grade. We shape the lot so water moves away from the structure and off your neighbour's land.
- Haul. Spoil, debris, and demolition material get loaded and hauled off-site.
- Final walkthrough. We leave the site clean and graded, and walk it with you before we call it done.
Frequently asked questions
Do I need locates for a small dig on my own property?
Yes. Ontario law requires locates through Ontario One Call before any dig, even a single post hole, on any property. It's free, and we book it on every job, we submit the request at least five business days ahead so the gas, hydro, water, and telecom lines get marked before we break ground.
Will my excavation need a conservation authority permit?
It depends on where your lot sits. If the dig is near a watercourse, floodplain, wetland, or steep slope, the Hamilton Conservation Authority may require a permit before any site alteration under Ontario Regulation 41/24. Most ordinary backyard digs aren't in a regulated area, but we check and confirm with the HCA before we start.
How deep do you dig for footings and foundations?
Footings and foundations have to bear on undisturbed soil below the frost line, which is about 1.2 m (4 ft) in the Hamilton area. Getting below frost is what keeps a structure from heaving when the ground freezes and thaws. We dig to the depth the job and the Building Code call for.
Can you get a machine into a tight downtown lot?
Usually, yes. The century-home lots in Durand, Corktown, and the older lower-city blocks are tight, but we plan the access before we show up, the gate width, the side-yard room, and what has to be protected on the way in. If a full-size machine won't fit, we work the dig in a way that does.
Do you handle grading near the escarpment and on clay?
Yes. Heavy clay up on the Mountain holds water, so the grade has to carry runoff away from the foundation on its own. Escarpment-edge lots can sit on shallow soil over rock, which changes the dig. We read the soil and slope on your lot and grade to move water the right way regardless of what's underfoot.
