FAQ
What is core drilling used for in electrical and construction work?
Core drilling creates clean, circular holes through tough materials like concrete, asphalt and brick. These holes allow for safe and accurate installation of electrical conduit, plumbing, HVAC ducting, data cabling and other infrastructure. It's a precise, low-impact method often used during upgrades, renovations or new installations.
Can core drilling be done in hard-to-reach areas?
Yes. With the right equipment and experience, core drilling can be carried out in tight, awkward or elevated spaces — including walls, ceilings, tunnels and confined areas. Professional drillers use specialised rigs and vacuum systems to manage dust and debris, even in sensitive or high-traffic environments.
Is core drilling noisy or messy?
While drilling through concrete and other dense materials naturally generates some noise, modern equipment is designed to reduce impact. Most jobs use a wet vacuum system to manage dust and slurry, keeping the workspace cleaner and reducing the need for post-job cleanup. It's a much tidier process than many expect.
