Diamond core drilling makes perfectly round, clean holes in concrete — no hammering, no cracks, no damage. It's THE way to go through a slab or foundation wall.
Most common uses
- Plumbing: pipe pass-throughs, French drain, sewer outlet
- Electrical / cabling: wire pass-throughs between floors, service entries
- Ventilation / HVAC: dryer vents, air exchangers, range hoods
- Commercial buildings: network cable pass-throughs, sprinklers, technical sleeves — see our commercial section →
- Concrete testing: core extraction for strength analysis
Why coring instead of a jackhammer?
- Perfectly round, clean hole, easy to seal
- No cracks in the surrounding structure
- Quiet and dust-free (wet cutting)
- Fast: a standard hole often takes under an hour
$150 – $400 / hole
Depending on diameter, thickness and access. Volume discounts for multiple holes — common in commercial projects.
