DIY Concrete Installations– the best ways to get it done correct the very first time

Just one of the significant challenges with an installation is having a task that deals with concrete. Mounting onto concrete will involve core-drilling the holes into your concrete base and setting the posts with a speedy set grout. Considering this involves drilling into concrete, it can be more risky than simply attaching to a timber deck. A choice here is to have your fence line marked out, the position of where each post or spigot (mini-post) also marked distinctly and then to get the professional services of a concrete cutter. This would certainly remove the need to hire or buy an expensive concrete core-drill and most concrete cutting/drilling companies will often give you a fee per hole that you want cut.

Core-drilling Tips for Concrete

Safety and security is always essential! So if you do decide to drill the holes yourself please keep the following points in mind:

  • Always ensure your core-drill is safe to use mechanically and has no tears or splits in the electrical cord.
  • If using the hand-held selection ensure that the cable will not be wrapped around any piece of your body or nearby constructions.
  • If using the portable machine version with a platform, see to it that the area around the drill body is clear of any clutter and or other building products.
  • * Important * Always make certain that the core drill bit is vertical and that it could run down the full depth of the hole without going to one side. This is very important because if the drill piece does go slightly off the vertical axis it will snag on the edge of the hole and pitch the drill. This can cause major injuries to the operator.
  • Before drilling ensure there is adequate water supply to the drill and the water is activated, not only at the tap but on the core drill tool too.
  • When drilling, keep the down resistance up to the drill. If there is inadequate pressure applied, the drill bit will not cut down, if there is excessive force applied then the core-drill bit may cut a bit quicker but the bit will lose its edge quickly and not last.
  • After the core has actually been drilled and you have a round section into the concrete, the core can be removed sometimes with a gentle tap with a metal hammer on a slight angle. If it doesn’t come loose using this then try to edge a small cold chisel into the gap and softly tap it so to not harm the concrete or tiles, or whatever your surface is.
  • Some concrete will have steel reinforcement embeded in the concrete and this may be grabbing as you attempt to remove the core. It is best to gradually increase the force of your tapping with the cold chisel up until it comes loose. This will ensure there is no collateral damage to the bordering floor.
  • Once the core has come loose from the bottom then you can merely lift it out. If you can’t get an adequate grip then would suggest using a pair of metal kitchen tongs to grab the edges of the core. If it still doesn’t really want to come out then it is most likely that it is still fastened by some reinforcing steel. Complete the drilling technique in the same hole.
