Guide to Concrete Coring


The process of concrete coring explained

Concrete coring or concrete core drilling is the process of removing a concrete cylinder from a structure. Some of the concrete coring applications are utility holes, drainage, maintenance holes, HVAC, and structural testing.

We use concrete core drilling for both diagnostic testing and specific concrete removal.

How does concrete coring work?

Concrete coring utilizes a diamond cutting drill to cut a perfect round hole in any concrete structure – in a floor, wall, or ceiling. The process is low-noise, dust-free and non-percussive, meaning it is the most popular choice for cutting.

Concrete coring uses a drilling tool made with a diamond cutting end attached to a steel tube to pierce concrete. Holes can be drilled at any angle – whether vertical or horizontal. We can use electric or hydraulic rigs for drilling in sensitive locations or confined spaces.

As the rig drills, we cool the cutter with water to reduce friction. When the cutting process is complete, we remove the slug, leaving a perfect hole with no cosmetic damage or aftercare requirement.

What are the applications of concrete coring?

There are many applications across various fields, including plumbing, electrical, drainage, HVAC, the creation of vaults and maintenance holes, and structural testing. Most commonly, we core concrete for utility penetrations.

Some examples of concrete coring use:

  • Utility Penetrations
  • Water Pipes
  • Sewer Lines
  • Air Circulation
  • Phone Lines
  • HVAC Openings
  • Computer Lines
  • Aggregate Analysis

Coring is necessary whenever there is a requirement for a hole through concrete or the aggregate needs to be analyzed.
