Concrete Cutting Tips You Should Know

The durability of concrete makes it ideal for use in most construction projects. However, its toughness usually makes it challenging to repair or make modifications to existing concrete structures. This is so especially when it comes to cutting it. The following are concrete sawing tips that will come in handy in helping to make your sawing work as problem-free as possible.

Don't force the saw into the slab

Trying to force your saw into a concrete slab won't make it cut any faster. This is because applying force on your saw simply increases the risks of the blade's saw overheating. And since overheating increases the odds of the blade bending or getting torn, it not only makes your saw vulnerable to damage, but also decreases the blade's ability to cut through concrete.

Holding the saw in such a way that only its weight and that of the blade do the cutting is the ideal techniques to use on a material that is as hard as concrete. This, in addition to lifting the saw and allowing the blade to run free for a couple of seconds, will reduce the risks of overheating and will increase both the durability and efficiency of the saw.

Use water

The serrated rims of a dry-cutting blade usually allows for two things: cooling and waste escape. However, when cutting a concrete slab, the rate of cooling that the nature of these blades makes possible is rarely enough to dissipate the heat that is generated from the cutting. The concrete dust that escapes from the cut also needs managing.

Using water when sawing a concrete slab is advisable since it not only helps to keep the dust under control, but also cool the blade. Cooling the blade usually keeps the blade from bending. It makes making cleaner cuts possible while also increasing the cutting effectiveness of the blade. Using water when cutting concrete usually creates a slurry mix that is way easier to control, making for a smoother cutting experience.

Use a harder material

Different concrete mixes usually have varying degrees of hardness. And since diamond blades depend on friction to expose the diamond cutting edges, the cutting effectiveness of a given blade is bound to vary depending on the hardness of concrete that is being cut.

If you find that your diamond blade has stopped cutting into your slab, having a harder piece of concrete will come in handy. Simply use the blade to cut into the harder material. Doing this will expose the diamond cutting edges faster, something that will then restore the blade's cutting ability. When this is done at intervals, it will make for a less-labored cutting process.
