Understanding Concrete Core Drilling

According to the Royal Society of Chemistry, concrete is the most widely used building material in the world. While it is already a remarkably strong and hard substance, the tremendous amount of energy it requires to produce is motivating scientists to create an even harder concrete. This will hopefully result in building projects requiring less concrete to obtain the same or better energy engineering strength.

Depending on the region of the United States where concrete is made, it ranges on MoHS (Measure of Hardness Scale) anywhere from 3-7. A diamond is the hardest substance in the world, coming in at number 10.

Just as large holes must be drilled through wood when homes are constructed to allow for the passage of wires, pipes, and HVAC (heating, venting, and air conditioning) components, large holes must also be drilled through concrete buildings. As concrete becomes harder in time, concrete cutting services will grow in importance. Here is what you should know about this rarely discussed, but important part of the building process.

How Is Concrete Drilled Through?

In order to drill through solid concrete, a powerful drill and a diamond drill bit are needed. The diamond drill bit is attached to a steel tube. Core drilling companies have to capacity to drill cores as small as an inch or less to several feet in diameter. Depending on the hardness of the concrete and the size of the hole, they may drill it dry, or they may use water to reduce the heat and friction.

For small holes, the drill may be handheld, but most applications require a drill that is mounted on a base or is held in place by suction. The drill removes a solid cylindrical core of concrete from a solid piece of concrete. Once the core is removed from the concrete, it is removed from the drill's steel core.

What Applications Require Concrete Core Drilling?

Concrete coring is used primarily for running utilities. Virtually every building must have running water, electricity, and heating. Large skyscrapers that house offices also usually need air conditioning and ventilation systems. Additionally, the way business is done has changed since the computer came to be, so now, not only are telephone lines important, but fiber optic cables are needed as well. Without concrete coring, all these wires, pipes, and cables could not be run throughout a building. Concrete coring is also used for other applications. For example, manholes can be drilled in the street, or blasting holes can be drilled through rock, enabling the demolitions expert to insert dynamite.
