Methods of concrete cutting Sydney

Concrete cutting Sydney is the process of removing, drilling, or blasting through hardened concrete in a controlled and supervised manner. Examples of such works include drilling holes, removing slabs, breaking through walls, or destruction of a structure.

The methods of concrete cutting to employ depend on the job you want to carry out. Some concrete cuttings are more challenging than others and require stronger abrasives, while other concrete cutting jobs are more delicate than the others, and they need softer abrasives.

Diamond Sawing

The sawing tools are rotary blades laced with diamond grains, and make straight cuts on concrete materials. Diamond is one of the most rigid materials in the world; this makes an excellent cutting tool.

Diamond sawing does not affect the surfaces they cut, and the cutting tool is less likely to wear or corrode. It also makes accurate cuttings and leaves just little cut residue.

Core drilling

Core drilling is a concrete cutting method for creating cylindrical cuts or holes in surfaces. They use cylindrical drills installed into a rotary machine which you mount over the area you want to drill. Core drilling creates openings for pipes, air-conditioning vents, or ventilating units.

Core drilling processes are mostly delicate processes, and you should employ the services of professionals before you drill.

Wire Sawing

Where concrete cutting is difficult and almost impossible, you have to use wire saws to cut through the concrete. Wire saws are made from thin wires with diamond lacings, which allows them to cut through any intricate shape in a structure.

Wire sawing is the most versatile of all methods of concrete cutting, as they can penetrate and cut over most materials. Wire saws cut through concrete in reinforced rebar, large concrete walls, and reinforced concrete.

Flat Sawing

This method is for removing concrete on flat surfaces like floors, bridges deck, or other slabs; you need to place the cutting tool on a cart and push it. When you compare it to the conventional method of hammering, flat sawing is a very efficient and quick method for cutting concrete on horizontal surfaces, with lesser stress. Some popular applications of flat sawing are:

• Cutting on sidewalks

• Highway renovation & patching

• Residential and commercial improvements

Wall Sawing

This method is useful in the cutting of windows, doors, stairway openings, and other vertical platforms. It is just the 'upright' form of the flat sawing, and the cutting tools are similar. The cutting tool is installed in carts and pushed in sideways/up-down direction on the vertical platforms. Its tools can be driven electrically, with gasoline or hydraulic engines.

Hydraulic bursting

It is a very noiseless, easy, and dust-free method of breaking concrete. It makes use of bursters to supply the area to be cut with an enormous amount of force per area. The pressure build-up in the area cracks will crack the concrete; separate it from the structures.

Hydraulic bursters use hydraulic fluids that can be powered by gasoline or electricity. This method is efficient for large concrete breaking.

Pneumatic Bursting

It is similar to the hydraulic bursting method, only that:

• Professionals use it for smaller and faster concrete cutting/blasting jobs

• It has a pneumatic unit (air) rather than hydraulic fluids.
