Installing Pipes in Concrete Wall Blocks
Posted Jan 27th 2014 | By:
This is not an easy venture when it comes to pipe installation. The manual process of drilling a hole through concrete can be harrowing at best, and the equipment necessary to get the job done can be expensive. However, expenses can be minimized through renting the equipment, or all the better if you have a friend who has such equipment. It is a necessary job if you plan to add a bathroom, or any type of plumbing fixture in your basement, and it could save you a bundle by not having to deal with a contractor. The type of drilling I'm talking about will be for concrete block walls, the most common type of construction for garage or basement walls.
The main piece of equipment you'll need will be a core drill, a heavy piece of machinery that is very expensive to use, and requires plenty of handling. However, there are some portable and lighter models for one-man jobs.

For other versions, you'll have to have some muscle to deal with this type of equipment, and you may need the assistance of another to help you move it. You'll also need to have some water nearby, since the drill diamond bit can get very hot as drilling commences. There will usually be a water feed source connector that will keep the diamond bit cool while drilling. But the good news is that it is a fairly simple process, and the drill bit required is usually large enough to install pipes. Use a core drill bit size that is one inch larger than the pipe to give you some extra space when fitting the pipe. Always wear goggles or protective clothing when drilling. If you are buying a new piece, it will come with instructions, or ask an associate about using the drill before renting it.
Also, you will need to get a inch hammer drill to help anchor in the core drill.

When applying the core drill, do not force it, but instead use consistent pressure. The best thing to know is to let the drill do most of the work. Forcing it too hard can tear the diamond bit from the mount, resulting in a damaged piece. And since this form of equipment is not the cheapest, you'll want to tread carefully.
Once all is finished, install the pipes and make the necessary connections. If you are dealing with an interior wall, expanding foam will keep the pipes fomented in places, but masonry patching is necessary for outside walls.
