Core Cutting India brings industry-leading, heavy-duty, dust-reduced Roof Cutting Services in Dharhara, Bihar, tailored specifically for residential, commercial, and industrial structures.
Modifying a cast reinforced cement concrete (RCC) roof requires precision, engineering knowledge, and specialized high-speed diamond tools.

At Core Cutting India, we utilize advanced hydraulic diamond wall saws, track saws, and wire saws to deliver razor-sharp, clean cuts without harming your building’s integrity.

When altering solid RCC slabs, precision and safety are paramount. Here is why property owners, civil contractors, and structural engineers in Dharhara trust Core Cutting India:
Comprehensive Roof & Slab Cutting Services Offered in Dharhara
We provide a wide range of concrete and roof cutting solutions custom-tailored for projects across Dharhara and neighbouring regions of Bihar:
1. Staircase Void & Opening Cutting
Creating a new opening for a spiral or straight staircase through a solid RCC roof demands exact dimensions and smooth vertical edges. We execute precise perimeter cutting so your structural frame remains sound and ready for stair installation.
2. Elevator & Lifts Shaft Cutting
Commercial buildings and modern multi-storey houses frequently require slab modifications to accommodate home lifts or commercial elevator shafts. We handle thick, high-grade concrete slabs with heavy steel rebar content smoothly.
3. Skylight, Ventilation & Duct Cuts
Improve natural lighting and air circulation inside your property. We cut smooth rectangular or circular voids for skylights, HVAC ducting, plumbing shafts, and exhaust vents across rooftops.
4. Edge Trimming & Cantilever Slab Modifications
Overhanging balconies, misaligned slab borders, or projected beam edges can be neatly trimmed down to accurate dimensions using our specialized wire sawing and track cutting units.
5. Controlled Roof Demolition & Segmental Removal
When partial or complete roof removal is necessary for renovation, we cut heavy concrete roofs into manageable blocks. These segments are safely lifted using cranes or rigging systems without disturbing surrounding structures.
Advanced Diamond Cutting Technology & Machinery We Use
Modern concrete cutting relies heavily on diamond technology. Core Cutting India deploys imported high-torque equipment to handle tough RCC slabs effortlessly.
-
Hydraulic & Electric Track Saws: Ideal for straight, deep cuts up to 500mm depth in heavy-duty reinforced concrete roofs.
-
Diamond Wire Sawing Machinery: Used for thick, heavily reinforced concrete structures where conventional blade diameters are insufficient.
-
Handheld Ring & Chain Saws: Designed for tight spaces, corners, and precise manual trim adjustments.
-
Core Drilling & Stitch Drilling Rigs: Employed along structural corners to prevent over-cutting and preserve reinforcing bars.
Step-by-Step Roof Cutting Process at Dharhara Sites
We follow a systematic, step-by-step approach to ensure maximum safety, site cleanliness, and speed:
-
Initial Site Assessment & Structural Survey: Our engineering team inspects the slab thickness, rebar arrangement, and load-bearing layout to select the appropriate cutting methodology.
-
Propping & Falsework Support: We install heavy-duty adjustable steel props directly beneath the cutting zone to secure the concrete segment being severed.
-
Precision Marking & Track Mounting: Guide rails are anchored to the target roof line using expansion bolts to ensure 100% straight and level cut edges.
-
Water-Cooled Diamond Sawing: Continuous water lubrication suppresses concrete dust completely while cooling the diamond blades, delivering ultra-smooth edges.
-
Controlled Block Lowering: Cut slab pieces are safely lowered down using chain blocks, hydraulic lifters, or crane rigs to avoid impact shocks.
-
Debris Clearance & Final Handover: The work site is swept clean of slurry and concrete fragments, leaving a ready-to-use opening.
Strict Safety Measures & Structural Integrity Standards
Cutting into load-bearing RCC roofs carries inherent risks if handled by untrained labor. At Core Cutting India, safety is integrated into every phase of our service:
-
No Structural Shockwaves: Unlike jackhammers and pneumatic breakers, our saw blades leave surrounding beams, columns, and structural footings entirely undisturbed.
-
Comprehensive Personal Protective Equipment (PPE): Our technicians are equipped with helmets, safety harnesses, anti-vibration gloves, eye protection, and dust respirators.
-
Dust & Water Slurry Containment: Wet cutting systems collect slurry at the source to prevent water seepage into lower levels of your property.
-
Propping Systems for Heavy Slab Slugs: Cut sections are clamped and hoisted safely to eliminate free-fall risks.

People Also Ask (PAA) & Frequently Asked Questions
Q1: Will roof cutting cause cracks in the rest of my house slab in Dharhara?
Answer: No. We use high-speed diamond blade track saws and wire saws that generate zero impact vibration. Unlike traditional manual jackhammers, diamond cutting keeps adjacent concrete, plaster, and structural beams completely intact and crack-free.
Q2: How long does it take to cut a staircase opening in an RCC roof?
Answer: A standard staircase void (e.g., $10\text{ ft} \times 4\text{ ft}$) in a 5-inch thick RCC slab typically takes 4 to 8 hours from track setup to final removal, depending on rebar thickness and floor access.
Q3: How do you handle slurry and concrete dust during indoor cutting?
Answer: We utilize wet-cutting diamond tools combined with slurry suction pumps and protective plastic sheeting. This process suppresses over 95% of airborne dust, keeping your interior space clean and safe.
Q4: Can you cut roofs with heavy steel reinforcement bars (rebar)?
Answer: Yes. Our industrial diamond saw blades and diamond wires cut through high-tensile steel rebars, TMT bars, and concrete simultaneously without blade jamming.
Q5: How is the price calculated for slab cutting in Bihar?
Answer: Pricing depends on running length (RFT), slab thickness (inches), steel density, floor height, and ease of site access. Use our online Rate Calculator or contact us at 7009679903 for a direct site quote.
Q6: Do I need to arrange electrical power at the site in Dharhara?
Answer: We require standard 3-phase or 1-phase power supply on-site based on the heavy machinery used. If site power is unavailable, we can arrange portable diesel generators upon request.
