Flat sawing technique is generally the ideal method for cutting horizontal surfaces such as floor slabs or pavements. It involves attaching a diamond blade to the machine, and the operator walks behind the machine, operating it as it progresses. This method is commonly used for tasks like joint cutting in concrete floors, cutting deteriorated pavement for replacement or removal, and cutting pavement sections for laying pipes like electricity, telephone, gas, water, and sewage. Core drilling method is used for creating holes in buildings for electrical, plumbing, and air conditioning systems, as well as for drilling holes for fence or guardrail installations. It is also employed for tasks like extracting test pieces for concrete strength analysis, drilling holes for anchor bolts in seismic reinforcement, line cutting when partially removing thick walls, and creating holes during the dismantling of concrete structures.
