The detail
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.
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, drain and sewer lines
- Gas and heating pipe penetrations
- Electrical and data conduit
- HVAC and vent penetrations
- Anchor bolts and dowel holes
- Sample cores for strength testing
- Handrail, post and bike-rack holes
- Utility work: manholes and water tanks
