One of the major obstacles with setting up a DIY pool fence is having a job that deals with concrete installations. Setting up onto concrete will involve core-drilling the holes into your concrete base and setting the posts with a rapid set grout. Due to the fact that this involves drilling into concrete, it can be far more harmful than simply fixing to a timber deck. An option here is to have your fence line marked , the position of where each and every post or spigot (mini-post) also marked clearly and then to employ the professional services of a concrete cutter. This would remove the need to hire or buy an expensive concrete core-drill and most concrete cutting/drilling companies will typically give you a price per hole that you want cut.
DIY Concrete Installations Core-drilling Tips
Safety is always crucial! So if you do decide to drill the holes by yourself please keep the following ideas in mind:
– Always ensure your core-drill is safe to use mechanically and has no cracks or splits in the electrical cable.
– If using the hand-held selection ensure that the cable will not be twisted around any piece of your body or nearby constructions.
– If using the portable machine version with a platform, make sure the area around the drill body is clear of any clutter and or other building components.
– * Important * Always make certain that the core drill bit is vertical and that it can run down the full depth of the hole without going to one edge. This is important because if the drill piece does go slightly off the vertical axis it will seize on the edge of the hole and pitch the drill. This can cause serious injuries to the operator.
– Prior to drilling ensure there is adequate water supply to the drill and the water is switched on, 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 insufficient pressure applied, the drill bit will not cut down, if there is a lot of force applied then the core-drill bit may cut a bit quicker but the bit will lose its edge promptly and not endure.
– After the core has actually been drilled and you have a round section into the concrete, the core could be removed sometimes with a gentle tap with a metal hammer on a slight angle. If it does not come loose using this then try to edge a small cold chisel into the gap and lightly tap it so to not damage the concrete or tiles, or whatever your surface is.
– Some concrete will have steel reinforcement set 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 see to it that there is no collateral damage to the surrounding floor.
– As soon as the core has come loose from the bottom then you can just simply lift it out. If you can’t get a sufficient grip then would advise using a pair of metal kitchen tongs to grab the sides of the core. If it still doesn’t really want to come out then it is likely that it is still attached by some reinforcing steel. Complete the drilling procedure in the same hole.
