Precise Round Openings, Cut Clean

Core drilling cuts smooth, accurate circular holes through concrete, masonry and stone using a diamond-tipped bit.

Whether it’s a single penetration for a pipe or a large-diameter opening for a duct or riser, we drill to the exact size, depth and angle your plan calls for. Cores come out clean with no over-break, so the surrounding slab stays intact and finished areas stay protected.

Every core is scanned first with GPR, so the bit avoids rebar, conduit and post-tension cables — reducing the risk of a costly strike.

What We Core For

Plumbing Penetrations

Holes for water, waste and drainage lines through floors, walls and foundations.

Electrical & Conduit

Clean openings for conduit runs, cabling and electrical service penetrations.

HVAC & Ducting

Large-diameter cores for ductwork, vents and mechanical rough-ins.

Risers & Sleeves

Vertical cores through multiple floors for risers, sleeves and service shafts.

Anchor & Dowel Holes

Accurate holes for anchors, dowels and rebar tie-ins in structural work.

Core Samples & Testing

Concrete cores extracted for strength testing and material analysis.

Our Coring Process

Scan & Mark

GPR checks the drill location for embedded steel and services before we start.

Set Up

The core rig is anchored and aligned to the exact size, depth and angle needed.

Wet Core

The hole is drilled with water cooling and slurry control to keep dust down.

Clear & Clean

The core is removed, slurry cleaned up, and the area left ready for the next trade.

Concrete Coring Questions

What hole sizes can you core?

Anywhere from 1″ up to 42″ in diameter. Tell us the size, depth and angle and we’ll bring the right rig and bits.

Do you scan before coring?

Yes — every core is GPR-scanned first to check for rebar, conduit and post-tension cables, helping reduce the risk of a strike.

Is coring messy?

We wet-core with slurry control to keep dust and water contained, so it’s suitable for occupied and finished spaces.

Can you core walls and ceilings, not just floors?

Yes — vertical, horizontal, overhead and angled cores are all possible with the right setup.

What can you core through?

Reinforced concrete, block, brick, stone and asphalt. Heavily reinforced or thick sections are no problem with the right bits.

What areas do you serve?

We serve Toronto and the Greater Toronto Area, including Mississauga, Etobicoke, Brampton, Oakville, Vaughan, Milton, Burlington, and surrounding areas.
