We drill clean.

What core drilling is

A core drill turns a hollow diamond-tipped barrel through the concrete, removing a solid cylinder and leaving a smooth, exact-diameter hole. Because it's a rotary cut rather than an impact, it doesn't crack the surrounding concrete.

Typical jobs

• Plumbing and drain lines
• Electrical and data conduit
• HVAC and vent penetrations
• Anchor bolts and dowel holes
• Sample cores for testing
• Railing and post holes

How NoCo does it

Scan first, mark the centre, anchor the rig, drill wet to depth, remove the core and leave a clean hole. Angled cores and stacked holes for larger openings are routine.

Every job starts with a scan

Every NoCo job starts the same way. We scan the slab or wall with ground penetrating radar to map rebar, post-tension cables, conduit and voids. Then we choose the right tool — a track-mounted wall saw for openings, a rig-mounted core drill for round penetrations, a walk-behind flat saw for slabs and pavement — and cut once, straight and to depth. When we open something up, our pour-back service can close it again with concrete matched to the surrounding grade and finish.

Who we work for

General contractors and builders who need openings cut on schedule. Plumbers, electricians and HVAC contractors who need clean penetrations without collateral damage. Property owners and managers modifying an existing building. Homeowners adding a basement window or a new door. Municipal and commercial crews cutting roads and slabs. Residential or commercial, one hole or a whole floor — the standard is the same.
