Concrete coring · Sydney

Core drilling, round, clean and exactly where you need it.

Diamond core drilling through concrete slabs, walls and beams for plumbers, electricians, fire services and HVAC contractors across Sydney. Scanned first, so you know what's in the way before we drill.

Core drill rig mounted on a wall

Core drilling is how services get through concrete. A diamond-tipped core barrel cuts a perfectly round hole through a slab, wall or beam and lifts the concrete out as a single solid core. There is no hammering and no spalling, so the surrounding concrete stays sound and the hole is ready for a pipe, conduit or sleeve.

Cutaway cores every day for plumbers running stacks and floor wastes, electricians needing risers and cable penetrations, fire services contractors and mechanical trades running ducts and refrigerant lines. We drill vertically through floors, horizontally through walls and at angles where the design calls for it.

Coring is a precise job, and the expensive mistakes happen when the drill finds a post-tension cable or a live conduit. That is why we scan before we core wherever the slab hasn't been cleared. One visit covers both.

Floor, wall and overhead coring

Our rigs anchor or vacuum-mount to the surface so the barrel runs straight and true. We core down through suspended slabs, sideways through block and concrete walls, and overhead where access means drilling up.

Wet coring keeps the barrel cool and the dust down. Water and slurry are controlled at the hole and below it, which matters when there's a finished ceiling or an occupied floor underneath.

Penetrations for every trade

Hole sizes range from small cores for cable and condensate lines through to large penetrations for stormwater, sewer stacks and ductwork. We match the core to the sleeve or fire collar you are installing.

On multi-level jobs we can set out and core a full stack of penetrations floor by floor, keeping them aligned so your risers run straight.

What's included

Concrete Coring scope.

The core of what we deliver. Every job is quoted to the site, so tell us what you need and we'll tailor the scope.

Plumbing penetrations

Floor wastes, stacks, stormwater and sewer through slabs and walls.

Electrical and data

Cable risers, conduit and communications penetrations.

Fire services

Sprinkler and hydrant penetrations sized to suit fire collars.

HVAC and mechanical

Ducting, refrigerant and condensate line penetrations.

Anchor and dowel holes

Holes for starter bars, anchors and structural fixings.

Concrete test cores

Cores taken for strength testing when your engineer requires them.

Our process

How the job runs.

Planned before we arrive, scanned where it matters, wet-cut and cleaned up before we leave.

Step 1

Set out

Confirm hole sizes, locations and depth from plans or your mark-up.

Step 2

Scan the area

Clear each location of reinforcement, conduits and post-tension cables.

Step 3

Mount and core

Rig fixed in place, wet-cored straight through, core removed whole.

Step 4

Clean up

Slurry contained above and below, holes ready for sleeves and services.

FAQs

Concrete Coring questions.

Can't see your question? Call 0400 929 963.

What size holes can you core?

We cover the range of everyday penetrations, from small holes for cables and condensate lines to large cores for stormwater, sewer and ducting. Give us the pipe or sleeve size and we'll core to suit.

Can you core through post-tensioned slabs?

Yes, but only after the slab has been scanned and the tendons located. Post-tension cables are under very high load and must never be cut. We scan, mark the safe zone, then core.

Will water leak through to the floor below?

We control water at the hole and set up containment under the penetration where there's a finished space below. Let us know what's underneath when you book.

How long does each core take?

Most standard penetrations take minutes once the rig is set up. Set-up, scanning and access usually take longer than the drilling itself.

Do you need power on site?

We can work from site power or bring our own. Let us know what's available when you book.
