Concrete core drilling is the process of removing a circular, clean cylinder of concrete from the rest of the product. Since concrete is a very solid material, the process of core drilling is usually performed via a diamond core drill.

Various environments may have limiting factors, such as noise-sensitive spaces, e.g. schools, healthcare facilities, etc. In such situations, core drilling is preferred as it produces fewer vibrations and noise than traditional hammer drilling. The process is non-percussive, dust-free, and low-noise, so it’s not surprising why it is the most popular choice.

The Process

The tool list for the concrete core drilling process comprises wet saws, chain, rock, floor, and diamond drills. A diamond cutting drill is preferred as it perfectly cuts and removes the cylindrical concrete core from the surface that needs to be cut. The remaining concrete cylinder in the drill is known as the “core”. Once the drilling process is complete, core drilling service providers remove the concrete from the wall to get the perfect holes. In a nutshell, the process is straightforward: create multiple holes in the surface via a diamond drill and then remove the concrete afterwards.

 

Methods

Depending on the type of the job and the desired results, concrete core drilling services use different methods and techniques. These include (but are not limited to) the following:

1.Rotary Core Drilling: It is one of the most common methods. It’s ideal for making perfect holes in concrete and rocks. Depending on the surface, both dry and wet drilling methods are used.
2. Hydraulic Core Drilling: This method is commonly used in construction sites. It is preferred when deep and large holes are required in a concrete surface.
3. Electric Core Drilling: This method sets up gas lines, plumbing, and electric lines.

 

Applications

Concrete core drilling services are used for a wide range of purposes. One of its primary purposes is to make way for new plumbing piping, electrical cables and conduits, and reinforcement (hold down bolts, starter bars, etc.). Core drilling is typically required to create openings through existing brick or concrete structures. Its applications include the following:

– Bollard installation
– Commercial fit-outs
– Routing cables
– Electrical conduits
– HVAC systems
– Plumbing piping
– Creation of utility holes and vaults, and more.

 

Advantages

There are many advantages of choosing core drilling for the applications mentioned above. Core drilling is suitable for sensitive, remote, and confined spaces. It is an ideal choice for projects of all scopes and sizes. Diamond drilling is particularly very popular for its unique benefits. The overall advantages include the following:

1. A non-percussion method which means no structural integrity issues;
2. Effective, safe, and quick drilling;
3. Tidy and clean work area;
4. Vibration-free with low noise levels;
5. Ideal for finished or confined areas;
6. Precise cuts for slots and holes.

 

In conclusion, engaging core drilling services are highly recommended if you want a perfect cylindrical-shaped hole in a vertical or horizontal concrete object. For the best results, employ the services of a reputable company that offers timely and cost-effective solutions to satisfy your needs.
