Green Park has an interesting mix of old DDA-built flats, redeveloped private bungalows, and modern builder floors near the market and metro stretch. Each of these comes with a different wall and slab structure, which means a core cutting job here can't be approached the same way every time. If you need a hole cut for an AC pipe, a drainage line, or electrical wiring through a concrete wall or slab, you need someone who actually checks what's behind that wall before drilling — not just someone with a machine.
We've handled core cutting jobs across Green Park's residential blocks, the shops near Green Park market, and a few institutional buildings closer to the IIT Delhi side, where wiring and plumbing routing often needs to pass through reinforced slabs. Each property type — be it a 1970s DDA flat with thick brick walls or a newly redeveloped four-storey builder floor — needs slightly different handling, and that's exactly where our experience makes a difference.
On this page, you'll find our complete pricing, process, equipment details, safety practices, and answers to the most common questions Green Park residents and shop owners ask before getting core cutting work done.
What Exactly Is Core Cutting?
Core cutting is the process of cutting clean, round (or sometimes square) openings through concrete, brick, or stone using a diamond-tipped drill bit that spins at high speed. It's the modern replacement for breaking walls with a hammer and chisel, which tends to crack tiles, weaken nearby masonry, and leave behind a lot of rubble.
In simple terms: instead of smashing a rough hole, we cut a smooth, exact-sized opening — the kind you need for pipes, cables, or ducting to pass through cleanly.
Why Green Park Properties Specifically Need Skilled Core Cutting
- Older DDA flats often have thick brick-and-mortar walls that behave differently from RCC under a drill
- Redeveloped builder floors usually have denser steel reinforcement in slabs, requiring rebar scanning first
- Shops and showrooms near Green Park market need quick, low-disruption cutting during non-business hours
- Properties near the IIT Delhi institutional belt sometimes have stricter compliance needs for any structural work
Common Situations Where You'll Need Core Cutting in Green Park
- Split AC or window AC pipe installation through external or internal walls
- New bathroom or kitchen plumbing connections
- Drainage and sewer pipe routing in ground floor or basement units
- Electrical wiring and conduit pipes between floors of a builder floor
- Overhead water tank pipe connections on the terrace
- RO purifier and geyser outlet pipe installation
- Internet, DTH, and cable wiring through external walls
- Exhaust fan or kitchen chimney vent openings in shops and homes
Core Cutting Services Available in Green Park
Wall Core Cutting
The most common request — clean circular holes through brick or RCC walls for AC pipes, plumbing lines, or electrical conduits.
Slab and Floor Core Cutting
Needed for vertical plumbing risers and wiring shafts that pass between floors, common in Green Park's multi-storey builder floors.
RCC Beam and Column Drilling
For anchor bolting or structural fixture installation, always done only after checking the load-bearing impact beforehand.
Terrace and Roof Slab Cutting
For water tank inlet/outlet pipes and solar panel cabling, finished with proper sealing to prevent water seepage later.
Basement and Ground Floor Cutting
Used for drainage and plumbing routing in basement storage areas or ground-floor commercial units near Green Park market.
Core Sampling for Structural Testing
Used by engineers to extract concrete samples and test strength before renovation or floor-addition approvals on older DDA structures.
How We Carry Out Core Cutting – Our Process
- Initial Site Visit – We inspect the wall or slab thickness, material type, and overall structure at your Green Park property.
- Scanning for Hidden Utilities – Before marking anything, we scan for embedded wiring, water pipes, and steel reinforcement.
- Accurate Marking – The exact position and diameter are marked, with extra attention paid to shared walls in adjoining builder floors.
- Machine Mounting and Stabilising – The core cutting rig is fixed securely to keep the cut straight, especially important on vertical surfaces.
- Diamond Wet Cutting – Water-cooled cutting controls dust effectively and keeps the cutting edge smooth and accurate.
- Immediate Debris Clearing – Concrete cores, slurry, and water are cleaned up right after cutting, so the area stays usable.
- Final Inspection – We check the hole's diameter, edge smoothness, and alignment before calling the job done.
- Clean Handover – No leftover dust, debris, or water marks on your floors, walls, or fittings.
Equipment and Technology Used
| Tool/Machine |
Application |
| Handheld Diamond Core Drill |
Compact holes (20mm–150mm) for cables and pipes |
| Rig-Mounted Core Cutter |
Heavy-duty cutting for slabs, beams, and thick RCC walls |
| Rebar/Utility Scanner |
Locating hidden steel, wiring, or pipes before drilling |
| Wet Diamond Bits |
Dust suppression and smoother, cleaner cuts |
| Dust Extraction Vacuum |
Used for dry cutting in furnished interior spaces |
| Wall Chasing Tool |
Creating shallow grooves for cable routing alongside core holes |
Regular bit maintenance and replacement is something we take seriously — a blunt diamond bit slows down cutting, generates more dust, and gives rougher edges, none of which we want on a Green Park job.
Core Cutting Cost in Green Park – What to Expect
Pricing depends on the diameter of the hole, the thickness and type of material (brick vs. RCC), accessibility of the cutting point, and how many holes are needed in one visit.
| Hole Diameter |
Typical Price Range |
| 1 inch – 2 inch (cables, thin pipes) |
₹250 – ₹500 per hole |
| 3 inch – 4 inch (AC pipes, drainage) |
₹500 – ₹900 per hole |
| 5 inch – 6 inch (plumbing risers, ducting) |
₹900 – ₹1,500 per hole |
| 8 inch and above (HVAC, large utility lines) |
₹1,800 onwards per hole |
| RCC slab/wall cutting (openings, per sq. ft) |
₹150 – ₹350 per sq. ft |
These rates are indicative and meant to give you a starting estimate. Properties with very thick RCC walls, basement-level access challenges, or multiple cuts in one visit may have slightly different final pricing. We always confirm the exact cost after a quick site check or even a video call — call 7009679903 for a same-day estimate specific to your Green Park property.

Cutting concrete inside occupied homes, shops, and older buildings needs more than just a powerful drill — it needs a careful process. Here's what we always do:
- Scan for rebar, wiring, and pipes before marking any cut
- Avoid cutting load-bearing walls, beams, or columns without prior structural assessment
- Lay protective covering over furniture and flooring before starting work
- Use PPE — gloves, safety goggles, dust masks, and ear protection — for all on-site staff
- Manage water usage carefully to prevent slurry damage near electrical points
- Take extra precaution while cutting shared or party walls between adjoining properties
- Recommend waterproofing after any terrace or roof slab cutting to avoid future leakage

Frequently Asked Questions
1. What is the price of core cutting services in Green Park?
Core cutting in Green Park usually costs between ₹250 and ₹500 for small 1-2 inch holes, while bigger 6-8 inch holes can range from ₹900 to ₹1,800 or more. Slab or wall cutting for larger openings is priced per square foot, typically ₹150 to ₹350, depending on thickness and access.
2. Is core cutting suitable for old DDA flats with brick walls?
Yes, but it needs a slightly different approach than RCC cutting. Brick walls cut faster but can crumble if the wrong bit speed is used, so experienced technicians adjust the drilling speed and pressure to avoid unnecessary cracking in older Green Park flats.
3. How long does a typical core cutting job take?
A single hole, around 2 to 6 inches in diameter, usually takes 20 to 45 minutes. Jobs involving multiple holes or slab cutting across floors can take 2 to 4 hours depending on material thickness and access.
4. Does core cutting cause cracks in nearby walls or tiles?
No, that's the main benefit of core cutting over manual hammering. A diamond core drill cuts a clean, precise hole without spreading stress cracks to the surrounding wall or floor tiles, provided it's done correctly.
5. Can core cutting be done in shops without closing for the whole day?
Yes, most single or double-hole jobs near Green Park market can be completed within a couple of hours, and we can schedule the work during early morning or low-footfall hours if needed.
6. What is the standard hole size for split AC pipe installation?
Split AC pipe holes are typically cut between 2 to 3 inches in diameter, though the exact size depends on the AC unit's pipe and drainage specifications.
7. Do you offer same-day core cutting service in Green Park?
For straightforward jobs like a single AC or plumbing hole, same-day service is usually possible depending on technician availability. Larger multi-hole or slab cutting jobs may need a day's advance booking.
