Diamond core drilling for HVAC, plumbing, electrical, and structural penetrations through slabs, walls, and foundations. Clean holes, set-price quotes, no travel charges.
Concrete coring produces clean, round penetrations through any concrete surface — walls, slabs, ceilings, and foundations — using rotating diamond-tipped core bits.
Coring is how trades get their lines through concrete. Plumbers need drain stacks through slabs. HVAC needs duct penetrations through walls. Electricians need conduit pathways. We drill the hole so they don't have to chip.
Our diamond core bits range from 1 inch to 36 inches in diameter. We drill vertically, horizontally, and at custom angles — upward through ceilings, horizontal through foundations, angled for drainage fall. Whatever your spec requires.
Rebar is not a problem. Diamond bits cut through reinforcing steel cleanly. We track rebar encountered during drilling and flag it if structural implications need to be checked with an engineer.
Every core job starts with a utility locate confirmation. We don't drill blind. Once cleared, we're set up and coring in minutes — small footprint, fast completion, clean result.
Every mechanical trade eventually needs concrete cored. Here's where we spend most of our time.
Drain stacks, sewer laterals, and water service entries through foundation walls and slabs. We match diameter to your pipe spec — no over-coring, no gap-filling nightmares.
Round penetrations for duct runs, HRV intakes, exhaust vents, and fresh air supplies through concrete walls and slabs. Sized to the duct collar for a clean, air-sealed fit.
Conduit runs through concrete walls and floors for panel feeds, sub-panels, and service entry. Multiple core sizes available for single or bundled conduit runs.
Utility entry points through poured concrete foundations — sewer laterals, gas service, communications, and weeping tile connections. Angled cores for proper drainage fall.
Core drilling through concrete slabs and walls for sprinkler head installations, fire suppression lines, and standpipe penetrations in commercial and multi-family buildings.
Coring for structural anchor bolt installations, geotechnical testing samples, and strength verification cores. We provide the clean hole — your engineer or inspector does the rest.
We core from 1 inch up to 36 inches in diameter. Common trade sizes: 4–6 inch for plumbing, 10–16 inch for HVAC, 2–4 inch for electrical conduit. We match the bit to your spec.
Yes. Diamond core bits cut through rebar cleanly. We note any rebar encountered and flag it if you need structural documentation. In critical areas we can shift slightly if the design allows.
Yes — horizontal foundation wall coring is one of our most common jobs. Sewer laterals, gas entries, and weeping tile connections all require horizontal cores, often at a specific angle for drainage fall.
A standard 4-inch slab core takes 5–10 minutes per hole. Foundation wall cores take longer depending on thickness. Most residential coring packages (multiple holes) are completed in half a day or less.
For most residential coring jobs, an adult just needs to provide site access and confirm the utility locate is complete. We work quickly and cleanly — most homeowners are surprised how fast it goes.
