Frequently Asked Questions (FAQs)
Q1: What is the cleanest method to cut an RCC roof slab in Kumhrar?
A: The cleanest and safest method is diamond wall sawing or wire sawing. It uses a continuous water feed to suppress dust completely, operates with minimal vibration, and leaves smooth, millimetric edges that require no additional civil plaster finishing.
Q2: Will roof cutting create cracks in adjacent walls or ceiling plaster?
A: No. When performed using diamond saw track cutters by Core Cutting India, there is zero impact vibration. Unlike jackhammers, diamond blades slice through concrete and steel rebar cleanly without stressing adjacent structural members.
Q3: How long does it take to cut a staircase opening in a residential roof?
A: A standard residential staircase opening (e.g., 10 ft x 4 ft on a 6-inch RCC slab) typically takes between 4 to 8 hours to mark, prop, cut, and safely lower the concrete block.
Q4: Do you offer site visits and rate estimations in Kumhrar?
A: Yes! We offer fast on-site inspections across Kumhrar and Patna. You can also estimate prices using our Online Rate Calculator or call us directly at 7009679903.
Q5: What safety precautions are taken during slab cutouts on upper floors?
A: We install heavy-duty hydraulic or steel props directly underneath the target slab section, bind the block with lifting slings, and use mechanical hoists or cranes to control the lowering process safely.
Q6: Can diamond blades cut through heavy iron rebar inside the concrete?
A: Yes. Industrial diamond blades and diamond wires are engineered to cut through high-tensile steel rebars, TMT bars, and high-strength concrete simultaneously without getting jammed.
