4 Things You May Not Know About Concrete Core Drilling

Blog

Concrete core drilling is a convenient way to create installation holes through concrete walls or floors. Through a drilling rig, diamond embedded blades are used to cut clean cores out of the concrete in just a matter of minutes. The open holes can then be used to install plumbing, electricals, anchor bolts, etc. However, there's more to concrete core drilling. Read on to learn some interesting facts about this technology and how it can help you in your applications.

Can drill at an angle

Most people think that concrete core drilling rigs can only cut through surfaces in perpendicular angles. This is not the case. The rigs can actually be positioned in any angle, be it vertically or horizontally. This means you have more flexibility when it comes to making your installations. By cutting through angles, you can have holes drilled directly in between two points without having to settle for straight cuts. When it comes to the collection of core samples, angle cores will provide better profiles and more data for studies.

Can drill to any depth

Although the diameter of concrete core drills is limited once you reach just over a metre wide, the same does not apply when it comes to drilling depths. The drilling rigs can cut concrete as far as you need. All that is needed is for extension bars to be added in between the cutting head and the rig.

Stitch drilling

In some cases, conventional core drilling is not possible with some concrete surfaces. A good example is where an extra-large hole needs to be drilled. Alternatively, the same case applies where a core is required but the sample cannot be cut in a circle because of other installations inside the concrete that should not be damaged. In such cases, stitch drilling is applied. Here, smaller cores are cut along the perimeter of the main core (stitching). Once done, the primary core at the centre is extracted.

Can utilize electric or hydraulic power

The other detail you might not know about concrete core drilling is that there are lots of power options available. While smaller rigs might use pneumatic force, most standard units are electric powered. However, many also use hydraulic power, especially the heavier units that carry out engineering or civil works. Therefore, depending on the location of the job or the scale of the drill, there are numerous power options to pick from.

If you need a concrete core drilling service, utilizing the above ideas could help make your project more successful. Talk to a concrete drilling contractor and find out how this can be achieved.

Creating a new parking zone

We have had a space out by the back of the shop for parking since the shop opened. But we noticed that fewer and fewer customers were using it and more customers mentioned the lack of parking in our area. It turned out that they didn't like parking on the back, unsealed lot as this made their shoes muddy and their car dirty. We used a concrete contractor to come and seal the carpark as well as mark out defined parking bays. The customers love it and we have noticed an increase in business. This site talks about how small businesses can create parking spaces with concreting to improve their customer experience.
