There are two basic approaches for controlling dangerous concrete dust while cutting, drilling, or grinding concrete: wet cutting and dry cutting. Knowing when to utilize each approach is critical for improving safety, selecting the proper machinery, maintaining saws and drills, and limiting environmental implications.
Wet Cutting Concrete – What Exactly Is It?
Wet concrete cutting entails directing a steady stream of water to the cutting surface to keep concrete cutting dust from getting airborne.
Utilizing water to reduce concrete dust is 85% more successful than employing dust extraction techniques in confining dust. Water aimed towards the cutting surface when cutting prevents dust from getting airborne in the first place, lowering the risk of inhalation or collecting on nearby furniture or valuables. Water also functions as a lubricant and coolant, extending the life of cutting blades.
Wet concrete cutting needs a dependable water supply, either from the mains or from a portable reservoir. It must be applied on equipment that will be safe to use while exposed to water. There must also be adequate containment and disposal of the concrete slurry.
Using Dust Extractors to Cut Concrete
Dry concrete cutting is when a customized dust extractor is attached to the concrete saw, drill, or grinder and sucks the concrete dust as it is made and collects it in a bag.
Because there is no need to connect a water supply, using an extractor is more adaptable. Electrical saws can also be used freely with an extractor without fear of electrocution. Finally, keeping the dust confined in a sealed plastic bag makes cleanup easier.
The major disadvantage of dust extractors is that they are ineffective in containing airborne concrete dust. There will still be concrete dust in the air no matter how good the extractor is, therefore there is a high risk of inhaling concrete dust. When cutting dry concrete, diamond-coated blades will also wear out faster. Finally, the gathered concrete dust must be properly disposed of.
When cutting concrete, it is critical to understand the advantages and disadvantages of cutting concrete in both wet and dry environments. It can have an impact on cleanup, the longevity of your saw, and, most critically, the quantity of dangerous concrete dust. Using a skilled concrete cutter will guarantee that concrete is cut in the proper manner.
