Cutting and coring is precision demolition. Somebody needs a hole through concrete for a pipe, a duct, a conduit or a drain, and the job is to make that hole exactly where it is needed, exactly the size it needs to be, without damaging anything structural and without covering the building in silica dust. Two techniques do most of the work. **Core drilling** uses a rotating diamond-tipped barrel bit anchored to the surface, producing a clean circular opening through a wall or slab, usually water cooled. **Saw cutting** uses a diamond blade on a walk-behind or hand saw to produce straight lines, either to open a trench in a floor or to cut a rectangular opening in a wall or slab. The step that separates good work from expensive mistakes is scanning. Rebar, post-tension cables, embedded conduit and buried services all live inside concrete, and none of them are visible. We scan before we cut. Where a bundle sits exactly where the opening was planned, moving it a few centimetres almost always solves the problem, and finding that out before the blade goes in rather than afterwards is the entire point. Dust control is the other non-negotiable. Silica dust from cutting concrete is a genuine health hazard and a serious mess. We wet cut with water collection where that is practical, and use HEPA-rated extraction where water cannot be used, such as over a finished floor or in an operating retail space. ### What’s Included - Scanning for rebar, cables and buried services - Layout and marking confirmed against your rough-in - Water-cooled diamond core drilling or saw cutting - Water collection or HEPA dust extraction - Break-out and removal of cut material - Debris removal from site - Clean, square openings ready for the following trade - Optional slab reinstatement after services are installed ## Common Work We Handle ### Basement Plumbing Trenches Basement bathrooms and laundry rooms need drain lines below the slab. We saw-cut both sides of the trench line, break out the concrete, remove it, and leave a clean opening for the plumber. Once the rough-in passes inspection, we can return to backfill, compact and repour so the floor is continuous again. ### HVAC and Service Penetrations Ducts, refrigerant lines, exhaust runs and electrical conduit all need openings sized correctly. We confirm the diameter against the actual equipment rather than working from a drawing that may have changed. ### Foundation Wall Penetrations Sump discharge lines, radon mitigation systems, water services and drainage all need cored openings through foundation walls. These get sealed or sleeved as part of the scope where required. ### Slab Openings for Renovations Stair openings, floor hatches, elevator pits and equipment pads all begin with a saw-cut opening. Where the cut affects structure, we discuss temporary support before anything is removed. ## How Much Does Cutting and Coring Cost in Toronto? Work is priced per opening at $150 to $400. Drivers: - **Diameter and depth.** A 50 mm core through a 150 mm wall is far quicker than a 200 mm core through 400 mm. - **Reinforcement.** Heavily reinforced concrete cuts more slowly and wears bits faster. - **Access.** Overhead coring, tight crawl spaces and awkward angles all take longer. - **Dust control method.** Full extraction in an occupied space takes more setup than an open outdoor cut. - **Quantity.** Multiple openings on one visit share the mobilisation, so the per-opening rate drops. - **Scheduling.** Out-of-hours work carries a premium against the disruption it avoids. Long trench cuts are usually quoted per linear foot rather than per opening, and we confirm which basis applies when we quote. ## Working With Your Other Trades Most of our cutting work sits between two other trades: somebody has designed the run, and somebody else is installing it. We coordinate directly with both where that helps. Confirming the opening size against the actual pipe or duct before cutting saves everybody a return visit, and it costs nothing to check. Because we run the full range of concrete work, the reinstatement after the services go in stays with the same crew. A trenched basement floor is repoured and blended, an opening cut through a foundation wall is sealed under concrete foundation repair [/concrete-foundation-repair/ →](/concrete-foundation-repair/) , and a cut across a warehouse floor is patched to match the surrounding commercial concrete flooring [/commercial-concrete-flooring/ →](/commercial-concrete-flooring/) . Saw cuts through a slab that is already breaking up are often a sign the floor needs commercial concrete repair [/commercial-concrete-repair/ →](/commercial-concrete-repair/) rather than another patch.

Brooklin Common questions ## Cutting & Coring FAQs ### help How much does concrete cutting and coring cost in Toronto? expand\_more Cutting and coring is priced per opening at $150 to $400. Small cores in thin walls sit at the lower end. Large cores, thick or heavily reinforced concrete, awkward access and long trench cuts sit at the top, and trench work is often quoted per linear foot instead. ### help Can you cut a trench in my basement floor for plumbing? expand\_more Yes, and it is one of the most common jobs we do for renovations. We mark the run with you or your plumber, scan for services, saw-cut both sides of the trench, break out the material and remove it, leaving a clean opening ready for the rough-in. ### help Do you scan for rebar before cutting? expand\_more Always. Cutting through a structural rebar bundle or a post-tension cable is a serious problem and an expensive one. Scanning lets us shift an opening a few centimetres to avoid it, which almost always works. ### help How do you control dust? expand\_more Wet cutting with water-cooled blades and core bits, with water collection where mess matters, or HEPA dust extraction where water cannot be used. Silica dust is a real health hazard and it is not acceptable to fill an occupied building with it. ### help Can you core through a foundation wall? expand\_more Yes. Foundation penetrations for services, sump discharge lines, radon systems and HVAC are routine. We core to the diameter your installation needs and can sleeve or seal the penetration if that is part of the scope. ### help How big an opening can you cut? expand\_more Cores up to around 250 millimetres diameter are standard. Larger openings are saw cut as rectangles and broken out. For a doorway or window opening in a foundation wall we would discuss temporary support and lintel requirements first. ### help How long does a typical job take? expand\_more Single cores are usually under an hour. A basement plumbing trench is typically half a day to a day depending on length. Multiple penetrations on a commercial site are scheduled together so you pay one mobilisation. ### help Do you refill or patch the opening afterwards? expand\_more We can. Once the trade behind us has installed their services, we return to backfill, compact and repour the slab section so the floor is continuous again. That is quoted alongside the cutting so you know the total up front. ### help Can you work outside business hours? expand\_more Yes. Occupied offices, retail units and restaurants usually prefer evening or weekend work, and we schedule accordingly. ### Still have questions?
