Concrete Contractor Toronto: Low-Dust, Occupied-Building Cutting and GPR Scanning

A concrete contractor built for Toronto’s dense, occupied sites

Toronto’s downtown core and high-rise condo construction leave little room for the dust, fumes and guesswork that come with the wrong cutting method. On active production floors, occupied institutional buildings and tight financial-district sites, work has to be clean, controlled and scanned before anyone starts cutting. Concrete Drilling & Sawing Ltd. (CDS) has been doing exactly that kind of work since 1967, and as a concrete contractor serving Toronto we focus on the methods that fit a dense urban environment: low-emission electric sawing, precise core drilling and scan-before-cut GPR concrete scanning.

We are family-run and one of Ontario’s longest-running concrete cutting companies. Our crews carry $5M liability insurance, full WSIB compliance and a current health and safety program onto every site, which matters when you are cutting inside a finished building or a busy commercial property.

Low-dust, low-emission methods for Toronto high-rise and downtown work

The reason electric equipment suits Toronto is straightforward: dense high-rise condo decks, financial-district institutional buildings and active downtown sites need methods that limit dust and emissions so the building can keep running. Our core concrete cutting services are built around that constraint.

• Electric slab sawing — low-emission cutting for occupied and indoor sites such as food-processing plants, large warehouses and active production lines, where diesel exhaust is not an option. Where a site is well-ventilated or outdoors, diesel slab sawing remains the faster choice.
• Core drilling — clean core drilling for the electrical, plumbing, HVAC and sprinkler-fitter penetrations that high-rise condo construction demands floor after floor, plus water-treatment and sewage work.
• GPR / NDT concrete scanning — our scanning crews locate rebar, post-tension cables, conduits and voids and produce detailed client reports. On post-tensioned condo decks, scan-before-cut is standard practice for us, not an upsell.
• Wall sawing and wire sawing — hydraulic and electric wall sawing for openings and demolition cuts, and diamond-wire sawing for very thick concrete, steel and hard-to-reach work in confined downtown spaces.

We also handle concrete removal, excavation, steel cutting, demolition and concrete crushing and recycling, so a Toronto project can be cut, scanned, removed and processed by one accountable crew. CDS also cuts anti-slip concrete grooving into ramps, loading docks and warehouse floors around Toronto.

Why scan-before-cut matters on Toronto condo decks

Tight downtown sites and post-tensioned high-rise decks are exactly where blind cutting causes the most damage. Locating tendons, rebar and embedded conduit before the first cut protects the structure and the schedule. Our GPR scanning produces a documented map of what is inside the slab or wall, so engineers and project managers can sign off with real data rather than assumptions. That same scanning work supports the major transit and infrastructure projects across the GTA that generate steady core drilling and scanning demand.

Industries we serve in Toronto

Our typical clients are the trades and firms running ICI (industrial, commercial and institutional) construction across the city:

• General contractors on commercial, institutional and high-rise condo projects
• Engineers and project managers who need documented scan reports before they cut
• Electrical, mechanical, and plumbing and pipefitting contractors needing penetrations
• Precast concrete manufacturers and commercial landscapers
• Demolition companies that do not cut or scan their own concrete

How we serve Toronto from our Hamilton shop

To be clear about logistics: CDS does not have a yard, depot or crew based in Toronto. We dispatch every job from our Hamilton headquarters, and Toronto sits squarely within our southern-Ontario service range. We mobilize the same day for emergencies across the Greater Hamilton area and the GTA, and next-day for most of southern Ontario. That coverage extends to North York, Scarborough, Etobicoke, East York and York, so a downtown core-drilling call and a Scarborough demolition cut are handled by the same crews and the same standards.

Beyond cutting and scanning, we support broader concrete construction work, giving Toronto general contractors a single source for the cutting, coring, scanning and removal side of a build. We hold a 5.0 rating from 7 Google reviews.

What sets our Toronto service apart

• Scan-before-cut GPR as standard, not an add-on
• Electric, low-emission equipment for occupied buildings (an ESG fit for institutional clients)
• $5M liability insurance, WSIB compliance and a current health and safety program
• Same-day emergency mobilization across the GTA from our Hamilton HQ

Frequently Asked Questions

Do you have a crew based in Toronto?

No. CDS operates from a single headquarters and shop in Hamilton, and all of our crews mobilize to Toronto from there. Toronto is well within our southern-Ontario service range, and we offer same-day mobilization for GTA emergencies and next-day service for most of southern Ontario.

Can you cut concrete inside an occupied building without shutting it down?

Yes. That is exactly what our electric slab sawing and core drilling are designed for. Low-emission electric equipment limits dust and exhaust, which is why it suits occupied institutional buildings, food-processing plants, large warehouses and active production lines where diesel is not appropriate.

Do you scan post-tensioned condo decks before cutting?

Yes. Scan-before-cut is standard practice for us. Our GPR / NDT concrete scanning locates rebar, post-tension cables, conduits and voids before any cut, and we provide a detailed client report so engineers and project managers have documented data to work from.

Which Toronto-area municipalities do you cover?

We serve all of Toronto including the downtown core, plus North York, Scarborough, Etobicoke, East York and York, and the wider GTA. Every job is dispatched and staffed from our Hamilton headquarters.

What concrete services can you handle on a Toronto high-rise project?

We provide electric and diesel slab sawing, core drilling for electrical, plumbing, HVAC and sprinkler penetrations, wall sawing, diamond-wire sawing, GPR concrete scanning, steel cutting, concrete removal and excavation, demolition, and concrete crushing and recycling. One crew can cut, scan, remove and process the concrete on a single project.

Are you insured and compliant for institutional and commercial sites?

Yes. CDS carries $5M liability insurance, maintains full WSIB compliance and runs a current health and safety program. We have been a family-run concrete cutting company in Ontario since 1967.
