If you are building or renovating in Hawai, you already know the challenges. The Lohit valley is beautiful but remote. Roads can be affected by rain and landslides. Supplies take time to arrive. And every job has to be done right the first time, because a second trip is costly.
That is exactly why a professional roof cutting service in Hawai makes sense. Instead of breaking a concrete roof with hammers, diamond saws cut it along exact lines. The opening is neat, the building stays steady, and your project moves ahead without repair headaches.
Core Cutting India provides RCC roof cutting, slab cutting, terrace openings and core drilling in Hawai and nearby areas of Anjaw and Lohit, including Walong, Tezu and Namsai. We also serve other parts of Arunachal Pradesh, Assam and cities across India.

Three Questions We Hear Most
1. "Can you really cut my existing roof without cracking it?" Yes. Diamond cutting is controlled and low in vibration. With the right propping, the surrounding structure stays stable.
2. "Will you travel all the way to Hawai?" Yes. We plan travel, equipment and schedule in advance for remote locations.
3. "How much will it cost?" It depends on the running feet, slab thickness and site access. Pricing is explained clearly in this page, and you can also use our rate calculator.
Quick Answer: What Is Roof Cutting?
Roof cutting is the process of cutting a concrete roof or slab along planned lines using diamond-tipped machines. It is used for staircase openings, lift shafts, ducts, skylights and removal of damaged sections. It is cleaner, faster and safer than manual breaking.
Why Careful Cutting Matters in the Hawai Area
Building in a remote valley region comes with its own set of risks:
- Limited access means a mistake is expensive to correct.
- Heavy rain and humidity can damage an exposed roof quickly.
- Slopes and steep plots make falling debris more dangerous.
- Slow material supply means you want to avoid damage that needs repair.
- Government and institutional buildings often have strict quality and safety expectations.
- Neighbours are close, so noise and dust spread quickly.
Diamond cutting reduces all these risks, which is why more owners and contractors prefer it.

Government, Institutional and Infrastructure Work
Hawai and the wider Anjaw district have many government offices, schools, health centres and infrastructure projects. These sites often need slab openings for stairs, lifts, ducts and services.
For such projects, we suggest the following:
- Share the drawing and cutting plan early.
- Arrange site entry permissions and any passes required for your location, as per local rules.
- Inform us about working hours and any safety rules.
- Plan for low dust and noise if the building is in use.
- Keep your engineer or consultant informed for approvals before cutting.
Our team follows your site rules and works with your project engineer to keep the job smooth and safe.
Our Step-by-Step Process
- You contact us with photos, slab thickness and opening size.
- We review and quote. You receive a clear rate and timeline.
- We plan travel and equipment, including water and power.
- We mark the lines exactly as per your plan.
- We secure the site with props, barricades and slurry control.
- We cut the slab and steel.
- We lower the blocks by pulley, rope or crane.
- We clean up and hand over a neat opening.
Safety on Every Job
Your roof is part of the load path of your building. We take these steps on every site:
- Check the slab, beams and columns before cutting
- Prop the section to be removed
- Use trained operators with helmets, gloves, shoes and eye protection
- Keep people and vehicles away from the area below
- Take extra care on wet, steep or uneven surfaces
- Control water and slurry near electrical points
- Pause work if weather conditions become unsafe
Please remember: If you plan to cut near a main beam or column, or open a large part of the slab, ask a structural engineer to approve it first. We will follow their drawing.

Planning Your Work Around Weather
The Lohit valley gets heavy rain in the monsoon. A little planning goes a long way:
- Cut in drier months when possible, so the next stage can start quickly.
- Cover and waterproof openings if the next stage is delayed.
- Avoid cutting in heavy rain, as wet surfaces add risk.
- Tell us about road conditions, so we can plan travel safely.
If your timeline is tight, call us. We will suggest the best approach for your site.
