Concrete cutting refers to the controlled process of sawing, drilling and removing concrete. There are a variety of methods used to complete the task, whereby proper machinery is required, usually different types of saws, to enable efficiency and accuracy, and most of all avoiding an entire mess, the job should be precise.
These methods include:
Also known as track sawing as it uses a machine mounted on a track using a circular blade which is used to cut holes in walls and vertical structures. The track is mounted on a wall or surface and the machine is run back and forth cutting the wall usually creating doors, windows or ventilation ducts. Wall sawing requires expertise and precision, therefore, should only be done by a professional, and such equipment should not be rented out to an amateur. The method is used to cut walls between 16-36 inches thick.
This method is used for cutting flat surfaces as the name would suggest, like driveways, parking lots and trenches in rehabilitation projects, the method is also referred to as slab sawing. An electric saw is better advised for this method of concrete cutting, a gas-powered saw can be, but the electric one is a better option. As they do not give off emissions they can are much kinder to the environment, however, they are dangerous to use on a wet concrete, they are much lighter in comparison though, therefore easier to move and maneuver.
This is yet another method that requires precision, in order for one to make holes through the concrete of any diameter from up to 60 inches. These holes are either be made mechanically, electrically or plumbing through walls, ceilings, and floors. This creates openings for wires, ventilation or air conditioning vents to fit properly. Again this is another method that requires professionalism, thereby important to hire one.
This is usually the method professional concrete cutters results when they need to cut large blocks of concrete. The equipment used here is a cable attached to a tiny diamond component supported by pulleys and integrated to a hydraulic power drive. Water is used as a lubricant during this process making it easy to reduce the large concrete chunks into more manageable sizes. That can also manage to make precision cuts where saws could not. This tool gets the work done and is not too expensive, however, care should be taken.
This method of cutting is similar to the workings of a carpenter’s circular saw. This type of equipment is on the much lighter scale, hence very effective and don’t tire one easily, they are commonly used to slice materials such as cider blocks. They hit a depth of about 6 inches and can effectively shave roughages and create small openings. It is, however, important to note that this type of saw should be used for much smaller construction projects, they would not be as useful if it was large-scale work.
This is a method that should only be used by contracts to be one the safer side. Besides that they have a tone of advantages, they are faster more precise and require fewer operations. To add on to the list, they are much quieter as creating fewer vibrations as compared to the other saw, and they are in a position to cut rebar and other metals. Easily the best option to battle with the durability of concrete and easily get the task done sooner rather than later, therefore, should greatly be considered in the case where one once to do a serious renovation that includes demolitions.
All these have their advantages as well as disadvantages, and consideration of the task at hand should be taken before settling on a particular method or saw. Hydraulic saws have the highest power to weight ratio and are convenient however they are more expensive. Gas-powered saws are popular as they are portable however they require a lot of maintenance. Electric saws are lightweight, simpler to use and better for enclosed environments, water is not their friend though. All these should be considered before a concrete cutting job is commenced, hence will be assured of a precise and properly done job.
