Tips For Core Drilling To Make The Task Easier

Posted on: 16 September 2016

When installing or working with concrete as part of an overall construction build, the cement needs to be as secure and durable as possible. Core drilling is typically done on concrete to test its core strength and overall durability, and is a very important aspect of the concrete contractor's job. After all, before a concrete sidewalk, overhang, or driveway is considered complete, it needs to be deemed safe and able to withstand the weight it is designed to support. While you may want to hire out this part of the concrete service you provide, you can do core drilling on your own without causing damage to your project. Here are tips for core drilling you can use for many construction projects involving cement. 

Choose the right drill

Since core drilling isn't the only thing you will likely need a drill for in your concrete projects, you want to choose a versatile drill. You can choose whichever diameter and horsepower of drill you want (based on the thickness of the cement you are working with), just make sure you pick a drill you can also use on wood, electrical work, and other parts of construction. If you don't plan on using a core drill for any other purpose than testing cement, then it's wise to rent a model instead. You can rent or buy a drill that is operated by air, electricity, or hydraulics. Choose whichever power style works best for your common job sites or personal preference.

Choose the right bit

The most common type of drill bit for core testing is a diamond bit. As a general rule, you want to use a diamond bit that matches the type of concrete you are working with. Harder concrete requires a softer bond diamond bit, whereas softer concrete benefits from a harder bond diamond bit. The right bit will allow you to effectively drill as deeply into the concrete surface you need to without causing cracking or stalling along the way.

If you have any concerns about core drilling, talk to an expert at your local concrete supply store or rental facility. You can then explain the type of project you are on to helpful staff who can guide you to choosing the best diamond drill for your needs. If you plan on keeping drills for future use, you may want to consider buying a variety of bits so you are prepared for every concrete job you encounter.

Getting Bids From Concrete Contractors

After we bought a home that had a large, completely unfinished RV pad, I realized that we needed to do something to fix it up. Instead of leaving it barren and ignoring the weeds, we decided to start getting bids from concrete contractors. We got bids from about ten different companies, and it was really great to hear what they could do for us. This blog is all about getting bids from contractors, knowing how to compare pricing, and avoiding issues with concrete. By taking a few extra steps, you might be able to completely avoid concrete problems and paying more than you should.
