When you need to install new utility lines through the basement, you have to drill through the concrete material used for the foundation. Concrete is a strong material, but this strength can work against you when it comes to drilling. Due to its sturdiness, it is best cored using a diamond drill. Unfortunately, just because you are making use of one of the hardest meterials to drill doesn't mean that the project will be easy. Various problems are bound to occur when drilling, and they can result in significant downtime. That's why you need the following tips to accomplish a successful concrete drilling project in your basement.
Use adequate water
Unlike dry drilling, diamond drilling involves wetting the concrete surface to clear dust from the wall and create a fresh surface for the drill to work on. Water also cools the drill bit and protects it from premature wear. One mistake that most people make when wetting the surface is using too much or too little water. When too little water is used, the drill bit will end up getting stuck in the core. Similarly, when too much water is used, the dust becomes too thick, and it seizes up the drill bit. So, the question is, how much is too much?
The secret is to use little water, but not so little that it does nothing to control the dust. Add water until the mixture resembles creamed coffee. You can also start with a little amount, observe the dust being produced and adjust the water accordingly.
Hold the drill correctly
If you are a renovation enthusiast, you are probably taking on the utility placement project without professional help. It's good to know that drilling requires the right technique is you don't want your bits to get stuck in the core. Plant your feet firmly on the ground and hold the drill with your two hands (like you would a gun). Start with slow speed and feel how the bit is breaking through the concrete. You can gradually increase the speed, but don't use much pressure as this will cause the equipment to overheat.
Watch out for wear
If your drill bits start to wear prematurely, you should stop working and identify the problem. The first sign of wear is when your bit develops brown, yellow, or black marks on the tip. Continued use will cause damage to the diamond. Turn of the drill and let it cool before proceeding. Also, reduce the speed and use some water to lubricate the concrete and cool the bits.
Follow these tips when drilling holes through your basement for utility lines. Consider hiring a drilling contractor if you don't have previous experience in handling concrete drills.
