What Is Concrete Core Drilling?
Core drilling is a process by which specific diameter holes are cored out through concrete walls and slabs in order to facilitate things like HVAC, plumbing, drainage, electrical services, and more.
Electric and hydraulic core drills use diamond coated bits in order to efficiently and accurately drill through hard materials such as asphalt, concrete and other masonry, and steel. The use of diamond coated bits also provides for a virtually vibration free drilling process, preserving the integrity of surrounding structure and materials.
Because diamond core drilling produces minimal dust and noise, it's well suited to sensitive and occupied work areas. For non-standard shapes and sizes, we use stitch drilling — overlapping a series of cores to cut out the exact opening needed. Need larger openings for doorways or trenches? See our wall cutting and slab cutting services.

FAQs
-
Core drilling uses a rotating diamond bit to extract precise cylindrical holes without fracturing surrounding concrete, unlike standard hammer drills that can create irregular openings.
-
Core drilling can produce a wide range of hole diameters and depths to accommodate plumbing, electrical, HVAC, and conduit requirements in commercial structures.
-
Yes, core drilling is designed to penetrate thick reinforced concrete, brick, and masonry with precision in most commercial applications.
-
For load-bearing walls or slabs, we evaluate reinforcement and structural conditions before drilling to avoid compromising the integrity of the structure.
-
Holes created by core drilling are immediately ready for installation of pipes, conduits, or ductwork without additional cleanup or shaping.
-
