Low-emission concrete cutting is Concrete Drilling & Sawing Ltd.’s (CDS) electric, zero-local-exhaust approach to cutting, coring and drilling concrete across Hamilton and all of Ontario. Since 1967 our family-run crews have run electric slab saws, wall saws, wire saws and core drills that generate no on-site engine exhaust — keeping indoor air clean, dust down and noise low inside occupied buildings. This page is the procurement hub for facility managers, ESG officers and general contractors who need a documented, low-emission cutting subcontractor for a tender or vendor-qualification file.
What Low-Emission Concrete Cutting Actually Means
Gas- and diesel-powered saws burn fuel on the work site, releasing carbon monoxide, nitrogen oxides and diesel particulate exactly where your staff and occupants breathe. Electric cutting eliminates that combustion at the point of work. Our machines draw power from the building supply or a spot generator positioned outside, so the blade, bit or wire runs with zero tailpipe emissions in the room. Paired with wet-cutting and vacuum slurry control, this is the cleanest way to open, section or remove structural concrete indoors.
- Zero local exhaust — no engine running in the occupied space, so no CO buildup or fume complaints.
- Low noise — electric drives are markedly quieter than gas saws, so adjacent areas can often stay in use.
- Controlled dust — wet cutting and slurry vacuums capture silica dust at the source.
- Occupied-building safe — suitable for hospitals, food plants, labs and offices that cannot be fully evacuated.
The CDS Electric Cutting Fleet
Low-emission concrete cutting is not one machine — it is a fleet. CDS matches the right electric tool to each cut so you keep the environmental benefit across the whole scope. These specialties are covered in depth on their own pages, and this hub ties them together for procurement.
Electric Slab Sawing
Our electric slab sawing crews make straight, precise horizontal cuts in floors, bridge decks and pavement for trenches, expansion joints and removal outlines — without the exhaust of a gas walk-behind saw.
Electric Wall Sawing
For vertical and overhead work, electric wall sawing creates door, window, elevator and HVAC openings and cuts wall sections free for removal, all on quiet electric power.
Electric-Powered Wire Sawing
Where a section is too thick or too awkward for a blade, our electric hydraulic wire saw pulls a diamond wire through mass concrete to cut large columns, piers and foundation blocks into liftable sections for demolition.
Electric Core Drilling
Electric core drills bore clean, round holes for plumbing, conduit, anchors and testing — from small penetrations to large-diameter cores — with the same zero-exhaust profile as the rest of the fleet.
Built for Occupied Buildings
The reason clients specify low-emission concrete cutting is almost always that people, product or sensitive equipment stay on site while we work. Electric equipment lets CDS operate in spaces where a combustion engine would be a non-starter.
- Hospitals and healthcare — renovations near wards, imaging and clean areas where air quality and noise are tightly controlled.
- Food and beverage plants — processing environments where exhaust fumes near open product are unacceptable.
- Schools, offices and data centres — occupied floors that need adjacent work to continue during a cut.
- Labs and pharmaceutical facilities — controlled environments with strict contamination limits.
Before any cut, CDS scans the concrete with GPR (ground-penetrating radar) to map rebar, post-tension cables and embedded conduit. Scan-before-cut is our standard, protecting your structure and your people whatever the tool.
ESG Alignment for Procurement and Tenders
ESG stands for Environmental, Social and Governance — the three lenses buyers now use to judge suppliers beyond price. When your tender or vendor policy asks for low-emission subcontractors, CDS gives you a documented answer in each column.
- Environmental — electric, zero-local-exhaust equipment plus wet dust and slurry control cuts on-site emissions and airborne silica, supporting your air-quality and carbon reporting.
- Social — quieter, cleaner work protects the health of your occupants, our operators and the surrounding neighbourhood, and keeps facilities usable during construction.
- Governance — a family-run Ontario company since 1967, WSIB compliant and carrying $5M liability insurance, with paperwork and safety documentation ready for your procurement file.
For an ESG officer or facility manager, that means you can name a real, qualified low-emission vendor rather than leaving the requirement unmet.
How to Qualify CDS as a Low-Emission Subcontractor
Qualifying CDS for a low-emission scope is straightforward. Send us the drawings or a site walk and we will confirm which electric tools fit the work, then supply the documentation your file needs.
- Certificate of $5M commercial general liability insurance.
- Proof of WSIB compliance in good standing.
- Site-specific safety and scan-before-cut procedures.
- A scope that names the electric machines assigned to each cut.
Everything is coordinated through our full range of concrete cutting services, so a single low-emission subcontractor can handle sawing, coring, wire cutting and removal on one purchase order.
Serving Hamilton and All of Ontario
From our shop at 276 Ferrie St E in Hamilton, CDS mobilizes electric cutting crews across the Golden Horseshoe and throughout Ontario — Toronto, Mississauga, Kitchener-Waterloo, London, Brantford, the Niagara Region and beyond. Whether it is a single occupied-building core or a multi-phase low-emission cutting program, our family-run team has delivered clean, precise concrete cutting since 1967.
Frequently Asked Questions
What makes concrete cutting “low-emission”?
The equipment is electric rather than gas or diesel, so there is no engine exhaust released at the point of work. Combined with wet cutting and slurry vacuums that capture silica dust, the result is dramatically cleaner air, less noise and no on-site tailpipe emissions.
Can CDS cut concrete inside an occupied hospital or food plant?
Yes. Zero-local-exhaust electric saws, wall saws, wire saws and core drills are designed for exactly these settings, where fumes and heavy noise are unacceptable. We coordinate timing, containment and dust control so adjacent areas can keep operating.
Does low-emission equipment handle heavy structural cutting?
It does. Electric wall saws and electric-powered wire saws cut thick walls, columns, piers and mass foundations, creating openings and freeing sections for removal or demolition. You do not trade capacity for the cleaner emissions profile.
What ESG documentation can CDS provide for our tender?
We supply proof of $5M liability insurance, WSIB compliance, and our scan-before-cut and site-safety procedures, along with a scope naming the electric tools used. That covers the environmental, social and governance evidence most vendor-qualification files request.
Do you scan before cutting?
Always. GPR scanning to locate rebar, post-tension cables and buried conduit is standard on every job, protecting your structure and keeping the work safe regardless of which electric tool we use.
Cleaner indoor air is the whole point; the EPA guidance on indoor air quality explains why cutting on-site emissions matters for occupied buildings.
