When you need to cut concrete, there are a number of different methods and techniques that can be used. The type of concrete cutting method will depend on the specific needs of the situation, such as: what is being cut, how deep it should be cut (for example for rebar), where it is being cut (for example in an area with water or gas pipes), and what equipment is available.
With that, you might be wondering: what are the different types of concrete cutting methods and techniques? If you’d like to learn more about this, feel free to read more below!
What Are The Types Of Concrete Cutting Methods?
There are a number of different ways to cut concrete, each with its own different pros and cons. The main two types of concrete cutting methods include the following:
1). Dry Concrete Cutting
Dry cutting involves using saws to cut through the surface of the concrete without adding any water or chemicals. It is known for creating huge amounts of dust. This is why it is often employed in outdoor jobs where there is more air circulation available. Diamond blades are commonly chosen for this method because they keep the saw from overheating without water around to cool them down. These varieties can also minimise any dust buildup that would otherwise occur due to an abundance of dry particles.
2). Wet Concrete Cutting
Wet sawing has been around for a long time and is still used today. Unlike dry concrete cutting, wet concrete cutting does not produce harmful dust particles. This makes this technique environmentally friendly and safe for humans too! Water is used to help the blade stay cool which prevents or minimises the production of hazardous substances from contaminating your work area.
What Are The Types Of Concrete Cutting Techniques?
Now that you know dry concrete cutting and wet concrete cutting as the two main methods of concrete cutting, what about the techniques? Here are some of them down below:
1). Slab Sawing
Slab sawing is a process that cuts concrete slabs into manageable pieces. The slab can then be delivered to building sites and broken down for use in construction projects. Levelling damaged pavement, providing control joints or laying underground wires and pipes are some of the common applications of the slab sawing technique.
2). Wall Sawing
Wall sawing allows for cuts in both the vertical and horizontal planes. Wall saws are long blades with circular or rectangular cross-sections mounted on an armature that allows them to be pushed against one side of your cut line while pulling away from the other edge at the same time. Wall sawing is used for cutting out concrete so that doors and windows can be installed. Because of this, these tools are mainly used in construction projects where the installation of doors and windows is required.
3). Wire Sawing
Wire saws are capable of producing highly accurate cuts or openings in steel and reinforced concrete. A wire saw is a type of diamond embedded cable that can be used both to create holes and openings with different shapes depending on the desired outcome, while also giving contractors great flexibility when working. Wire cutting minimises wastage as it doesn’t produce any cracks around an opening made by a contractor. Additionally, this technique offers tremendous benefits because there’s no vibration produced at all!
4). Handheld Sawing
Handheld saws are a great tool for cutting concrete. This is because they can be easily carried and used on the go, without any of the expensive machinery that is needed for other concrete cutting processes. It takes less time than most methods as well. Moreover, handheld saws typically have an adjustable blade and can be adjusted depending on what size you need them for.
5). Ring Sawing
Ring sawing is a fast and even cost-effective way to cut concrete because the blade moves in an orbital motion around the circular saw body. They are commonly used to break down large pieces into smaller, uniform-sized sections. Ring sawing is technically another type of handheld sawing. It is commonly used for small scale or medium scale concrete cutting projects because of this.
6). Core Drilling
Core drilling is a process that requires the use of drills with cutting bits to generate small holes in concrete. These bits have different shapes and sizes depending on what you are looking for, but they all serve the same purpose which is to make it easier when installing bolts or anchors. This technique also allows you to expose rebar and other steel reinforcement inside buildings or structures without having to take them down completely.
Concrete cutting is a process that can be done by hand, or with the use of machines. A variety of methods are available for this task and each method has its advantages and disadvantages. Ultimately, choosing which type of concrete cutting tool best suits your needs depends on what kind of job you have planned.
