Tips for Concrete Sawing: Build It Right!
The ultimate goal of the construction industry is not to just build something; sometimes, it is important to modify or remove already built structures. This removal process for changing the shape or size of the concrete can be carried out in many ways, concrete sawing being one of them. Concrete sawing is the process of cutting or removing concrete in order to drill concrete and make holes in them of various sizes and shapes, be it square or round, with a big or small opening.
What is the best Advantage of Concrete Sawing?
One of the best advantages of concrete sawing is that it does not take too much time or manpower to complete the process. More importantly, most concrete sawing systems are extremely precise and accurate, with automatic functions and specialized features for different kinds of concrete surfaces. It does not disrupt your surroundings with excessive noise or pollution. If done properly, it does not cause any vibrations in the concrete material, so the integrity and super strength properties of concrete stay intact, without any fractures in the material structure.
Things to keep in mind before a professional in Concrete Sawing:
There are various kinds of saws that can be used for concrete sawing. There are broadly two categories of cutting saws:
- Walk-Behind Saw: These are wheeled saws pushed by the operator so that the powerful blade of the saw can make incisions and cuts on the concrete surface below the wheel. Also called wet-saws, since they are dust-free, these are the most common kind, useful for situations like adding joints to roads and curb removal. Their use is especially for work on horizontal surfaces.
- Cut-off Saw: This type of saw is useful for more challenging situations like making holes in a vertical wall for a window, or to install water or power lines. This saw is hand-held and is much more accurate and controllable. Like regular circular saws, it uses around blade for concrete sawing. However, the blade is usually of a high strength material, so that it can withstand the wear and tear caused by concrete.
Saws can be operated with Machines or with Hydraulic Power:
- These saws can be powered by means of hydraulic compression, or air compression, or electric, or gasoline. Depending on the usage, different power sources are preferred. Hydraulic saws are the most powerful, so they are reserved for experienced personnel.
- Air compressors are economical, light-weight and easy to use. Gas-powered saws offer the maximum level of portability and movement. Electric saws, on the other hand, are the most light-weight, which makes them easy to operate for long durations of construction. These unique advantages make these different saws useful for different situations.
- With a standard bit, much less or more materials are often required to be excavated. That is the reason why many companies use the special diamond-tipped core drills for drilling.
The right saw is important to have the best concrete sawing output. Usually, powerful diamond blades are employed for concrete sawing. The synthetic diamond crystals on their surface are prone to falling off over time.
However, simultaneously, the new crystals get exposed and get the job done. Also important is the way one goes about the process of concrete sawing. It is important to mark the cuts before proceeding, preferably with a guide board held firmly on the surface. One should focus on starting with a few shallow cuts before delving deeper into the surface. It is safer, precise, and lets the blade stay cool as well.
There are multiple branded companies that are used for concrete sawing and core drilling. They have instruments and types of equipment like core drilling chains, saws and drilling machines that can drill through any thickness of concrete.
