Concrete cutting Sydney involves the demolition, shattering, or removal of concrete, either in; slabs, beams, and walls or floors partially or totally. Concrete cutting has to be done delicately and carefully, especially where the concrete material is a support for the structure(s).
Hydraulic bursting is one of the methods of concrete cutting, but unlike other methods, hydraulic bursting is a more advanced and stress-free method for concrete cutting. Hydraulic bursting involves a high, non-percussive pressure method, which consists of the use of buster heads inserted in holes previously drilled into the area close to the concrete part to be demolished or destroyed.
Before the hydraulic bursting is applied to the concrete, a hole is first drilled into the concrete material/structure. The hole sizes may vary (48mm to 200mm), depending on the thickness and toughness of the structure to be cut. Holes can be drilled using different drilling methods or materials, the most notable of them all being the diamond drilling machines.
Once the drilling is complete, the buster concrete grinding machine hire head of the hydraulic bursting machine is inserted into the drilled hole(s). Then, the pressure it exerts on the walls of the concrete, and the holes are increased to up to 2000 tons per square meter (2kpa).
The increased pressure exerted on the concrete makes the concrete crack up in larger areas at first, then continuous application further cracks it into smaller pieces. This ensures a safer and noiseless method of shattering the concrete structure. This pressure is maintained on the concrete structure until the whole concrete is shattered (for total structural demolition).
Advantages of Using the Hydraulic Bursting for Concrete cutting Noiseless and moderately inexpensive
The hydraulic bursting technique is a highly noiseless process, apart from the pre-drilling. Hydraulic bursting also involves the use of hydraulic (liquid) pressure, and this is an otherwise silent process. This can be very helpful in areas abhorrent to noise like hospitals, workplaces, schools.
