Is the term dry concrete cutting new to you? If yes, keep reading, and we will tell you about it. Diamond cutting is one of the most efficient and widely used methods for sawing concrete because they are less prone to fracture the surface of the concrete. Diamond saws are also renowned for producing cleaner cuts than other types of saws. They are made using synthetic diamonds that are incorporated into the saw blade, and when the crystals break, new cutting surfaces are exposed to the saw. There are two distinct approaches to cutting concrete with a diamond saw: the first is called wet cutting, and the other is called dry cutting.
However, in this blog, Advance Cutting will focus mainly on discussing the purpose of dry concrete cutting, its procedure, and aftercare.
When cutting in a dry environment, a specific diamond blade that is able to resist more heat is used. Small-scale construction often calls for the use of a hand-held saw that has a modest horsepower rating. Since the saw does not have a water reservoir for cooling, it relies on the air around it to bring the temperature of the blade down. Because of this, the blade has to be allowed to spin freely between cuts to maximise the flow of air. In order to collect concrete dust in a bag, you may use a dry-cutting saw in conjunction with a dust extractor or a vacuum.
The Purpose of Dry Concrete Cutting
Dry concrete cutting is a handheld method that is employed occasionally. It is most suited for small-scale applications such as ornamental patterning or in-house structures, where you want to maintain the work site as clean as possible.
To begin, the diamond-coated cutting blades used in dry cutters are also suitable for use in wet cutting machines. This versatility makes dry cutters a very useful tool. They perform well in both cutting and slicing motions without posing a threat of harm to the user or to the concrete. Cutting with a dry blade is preferable when doing menial jobs or when there is an urgent need for cutting, such as when you need to make repairs quickly and possibly have limited time to clean up.
Cutting in dry conditions is not only efficient but also helps to keep workspaces dry and makes them simpler to clean. In addition to this, working with a dry cutter is more pleasant for concrete cutting contractors because of how much simpler it is to handle. In addition to this, it enables you to cut considerably more rapidly while also providing enhanced control over the depth to which the cut is made. Lastly, dry cutters have a longer lifetime and spare you the effort of seeking for water to work on your project. This frees up more time for you to focus on the task at hand.
Methodical Procedure for Dry Concrete Cutting
Depending on the project and your particular preferences, decorative concrete cutting procedures may vary, but here are some common rules to follow:
Step 1: Evaluate your workplace
Assess your workspace to verify that it has enough ventilation and is devoid of impediments. You may use drapes to prevent dust from collecting on neighbouring objects and spaces. If the operation is being performed inside, gently cover any openings and HVAC systems to prevent the dust from spreading.
Step 2: Wear appropriate safety gear
Put on the required safety gear. Remember that anything in the air poses a risk to operators.
Step 3: Determine the proper cutting depth
Adjust the saw and blade to the proper depth. The body of the saw may be covered with masking tape to prevent the blade from damaging the concrete surface.
Step 4: Outline the areas to be cut
Mark your cutting lines with chalk or candle wax. Outside of the marks, place and fasten a straight board.
Step 5: Continue with dry concrete cutting
Typically, dry concrete cutting is meant for occasional usage using hand-held, low-horsepower saws. When sawing ornamental pattern lines into concrete, dry-cutting blades are often the best option for achieving precise, clean cuts. These ornamental incisions are generally just 1/16 to 1/4 inch deep and have no structural purpose.
To continue, firmly hold the saw by its handles. Be conscious of the incline of your starting point and steadily direct the saw’s motions away from your body and close to the cutting surface. The pressure you apply to the saw may vary depending on the direction of the cut. When cutting horizontally, the saw’s weight needs just guiding. When cutting vertically, more control and pressure will be required.
Step 6: Ensure no debris or obstructions exist on the concrete.
After cutting, verify that the region is devoid of water and dust. Be cautious of any sharp or jagged objects or edges, as well as loose concrete. You may use a chisel to remove tough areas and sandpaper to smooth off the finished area.
Step 7: Clean the workspace
With your protective equipment still on, remove any remaining water, dust, or debris from the finished work site.
Step 8: Disassemble and clean your saw
Disassemble and clean the saw and its blade. Check the manufacturer’s directions and ensure that your equipment is completely dry before storing it.
What Should You Do Following the Procedure?
Utilize dust extraction technologies, such as powerful vacuum cleaners with specialised air filters. These dust extraction devices are attached to a tool to aid in dust extraction at the cutting point. It is essential to ensure that the dust extraction equipment is suitable for the tool being used to successfully catch all dust. Ensure that the dust collecting bags and filters are periodically emptied, cleaned, and replaced to prevent them from becoming clogged or overfilled. Dry concrete cutting may not seem particularly hazardous at first look. However, you must have protective equipment and a strategy. Additionally, you must comprehend the safety standards. Lastly, respect for everyone’s safety on the work site. Without these items, you might very possibly suffer significant losses in the future.

5 Things You Can Avoid When You Hire A Dry Concrete Cutting Contractor
1. Hitting Things Than Can Cause Delay in Work
Many items can be concealed under a concrete wall or slab. It might have rebar, piping, or electrical lines in it. Cutting through concrete without first knowing what is inside would be a very bad idea. In light of this, the dry concrete cutting contractor ought to examine the layout to ascertain what lies beneath the concrete. Before cutting through concrete, concrete scanning and imaging may be used to determine what is below the surface if the blueprint does not provide enough information.
2. Inadequate Cutting Methods and Techniques
The method you use to cut the concrete will depend on the type of concrete you are working with. Dry concrete cutting involves more than merely drawing a chalk line and following it. Using improper cutting methods could result in tool and/or concrete surface damage. The cutter should choose the suitable equipment, lay down the cut saw lines or drill points, and then cut to the proper depth. The cutter should most importantly cut at the proper pace. Too much speed when drilling or sawing could harm the blade fragments. Additionally, you should cease cutting and polish the surface after the saw lines are no longer visible.
3. Using the Wrong Equipment
Using the wrong tools might harm the tool or the concrete surface. For instance, cutting or drilling through freshly cured concrete with equipment intended for older, dense concrete could result in harm to the concrete surface. However, the tool can be harmed by drills and saws made for recently cured concrete. When cutting various materials simultaneously, such a slab of concrete and tiles, the same rule applies. It is erroneous to believe that a diamond drill or masonry diamond blade can cut tile, asphalt, wood, or other materials. In order to handle the many sorts of material you can come across, you should switch to the proper blade, bit, or equipment.
To prevent making this error, your dry concrete cutting contractor must carefully assess the concrete slab before selecting the appropriate tools. To ensure that your tools easily cut through concrete, constantly keep them sharp.
4. Improper Curing
Concrete sets up in just two days after being poured. The recovery process could take up to 28 days. Inadequate curing may come from inappropriate curing processes and care. It’s crucial to look after the concrete and make sure it cures properly for the full 28 days. Otherwise, when being sawed or drilled, the concrete can collapse, split, or become unstable.
5. Inadequate Safety Precaution
The construction business is rife with hazards like noise, dust, and others. It is crucial that you take the appropriate safety measures. Dry concrete cutting is an unpleasant, dusty job. When ring sawing concrete, you should use personal protection equipment and adhere to safety regulations. For example, put on gloves to protect your hands, safety glasses to protect your eyes, work-appropriate clothing that fits snugly, and earplugs to protect your ears. Wear a face respirator, reflective clothing, a hard hat, and boots with steel toes as well. Finally, spray water on the concrete surface to reduce dust generation. When core drilling and concrete sawing, dust is a major problem. Dust generation and ejection from the concrete surface are reduced by wetting the surface.
When you are doing dry concrete cutting mistakes are easy to make especially if you didn’t hire the right person for the job. There are, however, a variety of ways you may increase the safety of your concrete cutting job, lowering the possibility of making errors that detract from the quality of the work. You should hire people who are skilled and knowledgeable about dry concrete cutting. Similarly, you can take safeguards to reduce the possibility of making errors that could endanger your health or the health of others at the worksite.
