Why Choose Diamond Roof Cutting Over Traditional Chipping Methods?
Traditionally, contractors in Bihar used heavy sledgehammers, jackhammers, and manual breaking methods to cut concrete roofs. While cheaper initially, manual demolition produces strong structural vibrations, leading to hairline cracks across adjacent beams, weakened columns, dust pollution, and uneven edges that require expensive plastering work.
Modern concrete roof cutting with diamond blades revolutionizes the modification process:
Applications & Use Cases of Roof Cutting in Dhaka
Our engineered roof cutting solutions serve a wide range of structural modification needs across residential, commercial, and industrial sites in Dhaka and East Champaran district:
-
Staircase Cutouts: Neat cutting through RCC floor slabs to make way for duplex staircases, spiral stairs, or escalators.
-
Skylights & Ventilation Shafts: Creating perfectly square or rectangular slab openings to allow natural light and fresh airflow inside multi-story houses.
-
Lift & Elevator Shaft Openings: Precision floor slab trimming for vertical elevator shaft installations in commercial complexes and hospital buildings.
-
HVAC & Pipe Duct Passages: Heavy slab cuts for running large air conditioning ducts, plumbing mains, and electrical conduits.
-
Partial Roof Demolition: Removing overhanging chajjas, balcony slabs, or dangerous structural extensions safely without harming main load-bearing structures.
-
Industrial Floor Jointing & Trenching: Deep blade cutting for drain channels, factory floor expansion joints, and equipment foundations.
Our Step-by-Step Diamond Roof Cutting Process
We follow a rigorous structural engineering protocol to execute every concrete slab cutting job smoothly and safely in Dhaka.
1. On-Site Inspection & Layout Mapping
Our engineers evaluate the concrete thickness, steel rebar density, beam locations, and load-bearing dynamics. Markings are made exactly according to your architectural blueprints.
2. Under-Slab Propping & Safety Rigging
Before making a single cut, steel props, jacks, and safety catching platforms are installed underneath the slab section being cut to prevent accidental drop-downs and ensure total worker safety.
3. Dust-Suppressed Wet Saw Cutting
We mount heavy-duty floor saws or tracks fitted with industrial water-cooled diamond blades. High-purity diamond segments slice through tough RCC, steel rebar, and hard aggregates smoothly while water suppresses all airborne concrete dust.
4. Controlled Debris Lowering & Disposal
The severed slab pieces (blocks) are safely lowered down using chain blocks or crane attachments, avoiding damage to lower floors. We cart away concrete debris to keep your construction site spotless.
Advanced Roof Cutting Technologies We Use in Bihar
To handle varied concrete thicknesses—from thin residential terrace roofs to heavy 300mm+ industrial concrete bridge decks—we bring specialized equipment directly to your site in Dhaka:
A. Electric Concrete Floor Saws
Ideal for flat horizontal roofs, terraces, and bridge decks. These high-torque walk-behind saws utilize 350mm to 1200mm diamond blades to execute straight, deep cuts up to 500mm deep at remarkable speeds.
B. Track-Mounted Diamond Wall Saws
When working on angled roofs, sloped slabs, or ceiling perimeters where floor saws cannot maneuver, track saws are anchored directly to the concrete surface to make laser-straight automated cuts.
C. Diamond Wire Sawing Systems
For ultra-thick RCC roofs, heavy mass concrete blocks, or silent demolition requirements near sensitive operational buildings, diamond wire sawing wraps diamond bead cables around the structure to slice through unlimited thicknesses effortlessly.

Personal Protective Equipment (PPE): Every crew member operates in full safety gear—helmets, steel-toe boots, eye protection, ear defenders, and safety harnesses for high-elevation roof work.
-
Vibration-Free Technology: Diamond blade sawing eliminates micro-fractures, safeguarding remaining roof slabs from future water leakage or structural weakening.
-
Dust & Water Slurry Containment: We use slurry collectors and wet-vacuum systems to maintain clean surrounding indoor spaces during modification projects.
Frequently Asked Questions (FAQs)
Q1. How much time does it take to cut a staircase opening on a roof in Dhaka?
Answer: A standard residential staircase opening (approx. 10 ft x 4 ft) in a 5-inch to 6-inch thick RCC roof slab is usually completed within 4 to 8 hours using our high-speed diamond slab saws.
Q2. Will roof cutting cause cracks in the rest of my house slab?
Answer: No. Unlike manual breaking with sledgehammers or jackhammers, diamond blade cutting uses non-impact rotary cutting. It creates zero vibrations, keeping the surrounding ceiling, beams, and plaster completely intact without hairline cracks.
Q3. Do I need to supply electricity and water at the site during cutting?
Answer: Diamond saws require a continuous water supply to cool the diamond blade and eliminate dust. Standard single-phase or three-phase electric supply is required based on the machinery used. If your site lacks high-power connections, let us know in advance so we can arrange portable generator setups.
Q4. Can you cut through thick concrete roofs with heavy steel TMT rebar?
Answer: Yes! Our diamond-impregnated steel blades and wire saws slice through high-grade reinforced concrete (RCC) containing heavy TMT steel bars seamlessly.
Q5. What is the cost of concrete slab cutting per square foot or linear foot in Bihar?
Answer: Cutting rates start around ₹150 to ₹250 per linear foot for standard 4 to 6-inch thick roof slabs. For precise budget calculations based on your project dimensions, use our online Rate Calculator.
Q6. Do you provide core drilling along with roof cutting services in Dhaka?
Answer: Yes, Core Cutting India provides complete structural concrete services in Dhaka including core drilling (for plumbing, electrical, and AC pipes), wall sawing, beam cutting, and floor trenching.
