Concrete Contractors in Toronto
In Toronto the concrete that gets searched for most is the wet-basement fix on an old brick house: waterproofing, foundation crack repair and parging on century walls from the Annex to Riverdale. We do that work, and the driveways, walkways and infill pours the rest of the city asks for. Union-certified crews handle every job, the labour carries a lifetime warranty, and the written quote costs nothing.
Toronto is the biggest city in the country, about 2.79 million people across the old city and the five former boroughs that joined it: East York, York, North York, Etobicoke and Scarborough. It is also the oldest building stock we work on. Whole districts went up before anyone sealed a foundation to a modern standard, and that single fact decides what most Toronto concrete calls are actually about.
Read the map and you read the work. The Annex, Riverdale, Leslieville and the Beaches carry brick homes from the late 1800s and early 1900s, with original poured or block foundations that have been holding back wet ground for a hundred years. The red-brick bungalow belts of East York, Scarborough and North York are postwar, newer but still old enough that the parging has weathered off and the footings predate current frost rules.
So the busiest job here is not a fresh pour. It is repair: waterproofing a leaking basement, injecting a foundation crack, re-parging a wall that has spalled down to the block. On top of that sits the newer work the city keeps adding, the laneway and garden suites going in behind older lots and the widened driveways and patios homeowners want once the rest is sound.

What the ground here does to concrete
Toronto was built on the Lake Iroquois plain, the flat lowland an ancient lake left along the shore of Lake Ontario, and the ground there runs to fine lacustrine clay and silt. Clay is the hard soil to own a foundation on. It holds spring melt and rain against a wall instead of draining it, and near the lake and the old streets the water table sits high, so pressure builds against basements that were never sealed for it. That is the engine behind the city's number-one concrete search, basement waterproofing.
The ravines make it sharper still. The Don and the Humber and the smaller creeks cut deep through soft clay and sand, and homes near those valleys sit on ground that stays damp well into the season. Add a Toronto winter of freeze-thaw swings and heavy road salt, and an old slab or an unprotected wall takes a beating every year. Whichever way a job leans, the base under the pour and the drainage around the wall are what decide whether it lasts.
Around Toronto
We quote right across the amalgamated city. The old-Toronto cores like the Annex, Riverdale, Leslieville and the Beaches lean almost entirely to repair: waterproofing, crack injection, parging and step rebuilds on century homes. The bungalow districts of East York, Scarborough and North York mix repair with driveway replacement, while Etobicoke and the wider lots take more flatwork and the odd laneway-suite pad. The older the street, the more the work is keeping water out; the newer the lot, the more it is a first proper pour.
Toronto is the far end of our range, a long haul east down the 401 and 407 from our home routes, so city jobs go onto planned trips with real dates booked in, never a same-day truck and never a promise we are minutes away.
Why does my old Toronto house keep getting water in the basement?
Two things working together: the clay the city sits on and the age of the wall. Lake Iroquois clay holds melt and rain against a foundation instead of letting it drain, and a brick home from the early 1900s was never sealed the way we seal one now. Water finds the weakest spot and pushes through. The fix depends on the wall, so it might be crack injection, exterior membrane and drainage, or interior weeping tile. We start from what the inspection finds, not from one system we sell to everyone.
What does parging do on a century Toronto foundation, and how is it different from waterproofing?
Parging is the mortar coat on the part of the wall you can see above grade. On the old block and brick foundations around the Annex and Riverdale it weathers off over the decades, leaving the wall exposed to frost and salt. Re-parging protects that face and tidies it up, but it is not waterproofing on its own. If water is getting in below grade, the parging goes on as part of a larger repair that handles the cracks and the drainage too.
Can you pour a concrete pad for a laneway or garden suite behind my Toronto lot?
Yes. Since the city opened up laneway and garden suites a lot of older properties are adding them, and the slab or footing underneath has to be done right because access off a narrow lane or a back garden is tight. We site-visit first to see how a truck and a pump can reach the back of the lot, then build the base to the ground there. Footings and slabs follow the engineering on your permit set.
Our 1950s Scarborough driveway is cracked and heaving. Repair or replace?
Depends how far gone it is. A bungalow-era driveway rarely got the base depth we use now, and Toronto clay heaves wherever frost reaches under a thin slab, so once panels lift and crack water keeps widening them every winter. Small damage resurfaces. Past a certain point, removal and a new pour on a proper compacted base costs less over the next twenty years than patching it again and again. We tell you straight which side of that line you are on.
How much does basement waterproofing or concrete work cost in Toronto?
It turns on the service, the size, the access and what the wall actually needs, and a downtown semi with no rear access is a different job from a North York bungalow at the same footage. We do not post flat rates, because an honest figure needs eyes on the site. The site visit and the written quote are free, and the number we give you is the number you pay.
