Originally diamond drilling was used in the mineral mining industry to extract a diameter core of rock from the ore body. Geologists used the core material to determine what minerals might be found in the surrounding area. The name is due to the fact that a diamond bit is used to drill. Modified versions of this process are now being used to accomplish a variety of tasks associated with construction. Diamond drilling in the UK is an environmentally friendly way to drill holes through concrete, brick or some type of reinforced block work.
One of the advantages of the process is that it prevents or minimizes spalling, which is the breaking apart of surrounding concrete. In other words to create the hole does not entail damaging the area around the hole. It also reduces spelcing, which is the rock or other material that breaks away as drill bit exits the rock, wall, or whatever is being drilled.
Diamond drilling is exact, neat and creates precise clean hole in the mass being drilled. The diameter of the hole may be just a few millimeters or quite large up to thousands of millimeters. This method reduces the noise factor and also prevents air pollution. The dust from making the hole is suppressed with a water feed.
One example of an application of this type of drilling is to drill ducting tunnels under the foundation of a house. This innovative process is able to achieve the task without disturbing the surrounding area. There is no need to tear up floorboard or dig trenches under the foundation. Since there is no demolition or repair of the demolition, using this process saves time and money.
The type of drilling only makes circular holes. The depth of a hole may be quite small or quite large to suit the task. A decorative hole may only be one hundred fifty millimeters in depth. Whereas a hole that is several meters in depth might be used to serve a utilitarian purpose, such as to accommodate some heating ducts.
This is an oversimplification, but it will serve to illustrate the process. In this example there is a concrete wall about one hundred seventy millimeters in depth. The objective is to make three matching holes close to the bottom of the wall. When finished the holes will be about six hundred millimeters in diameter.
First something called a holding down bolt is screwed into the wall. Next a large drilling rig is mounted to the wall with the holding down bolt; the motor is attached to the rig. The diamond core is next screwed onto the motor. Concrete is drilled with water, so the technician proceeds with drilling the first hole with a water feed from a barrel. The drill will penetrate through to the other side of the wall.
Once the job has been finished, all that remains to be done is to clear the equipment. There is no mess to sweep away since material removed from the wall has been sucked back into the water barrel.
Thanks to this process, there are many jobs that can be accomplished quite accurately and with minimal noise and clean up. This method of making holes of almost any size and in almost any location is revolutionary in the construction industry.
