Core Drilling

Concrete Core Drilling or Coring consists of drilling perfectly round holes through concrete walls, structures and floors. The diameters of the holes range from 1" to 12" round but average 5" for most standard homeowner applications. In some commercial applications core holes can range anywhere up to 60" round and more. Concrete Core holes are used for "utility penetrations" such as electrical, plumbing and heating but are also commonly used for venting pellet stoves, furnaces or clothes dryers.
