Coring Works
We provide professional core drilling and coring works in Singapore, using diamond core bits to create clean, precise holes through concrete, masonry, and other hard materials. Coring is commonly needed for installing piping, electrical conduits, air-conditioning lines, and other building services.
Our team uses specialised equipment to carry out coring work with minimal noise, dust, and disruption, whether it’s a single hole for a utility line or multiple cores for a larger installation project.
Diamond Core Drilling Services
We use diamond core drilling equipment to cut clean, accurate holes through concrete, brick, and masonry surfaces. This method produces minimal vibration and dust compared to traditional hacking, making it ideal for occupied buildings and sensitive environments.
Our team selects the right core bit size and drilling method based on the material and thickness involved, ensuring a precise result every time.
Wall & Floor Coring for Utilities
Coring work is often required to create openings for plumbing, electrical wiring, air-conditioning pipes, and other building services. We carry out wall and floor coring with careful attention to existing structures and utilities to avoid damage.
Whether it’s a single core for a pipe or a series of holes for a larger installation, we plan and execute the work to meet your project’s technical requirements.
Coring Works in Singapore: What Property Owners Should Know
Core drilling is commonly needed in Singapore homes and buildings for installing air-conditioning pipes, plumbing, electrical conduits, and other building services, since most HDB flats and condominiums are built with reinforced concrete. Whether you’re retrofitting an aircon system, running new pipework, or need openings for structural inspection, precise coring keeps the surrounding structure intact while getting the job done cleanly.
Before any coring work begins, we check for embedded services such as water pipes, electrical cabling and rebar, particularly important in older HDB blocks where utility layouts may not be fully documented. This helps us avoid striking PUB water pipes or SP Group power cables, which can cause costly damage and safety hazards if hit during drilling.
For coring through load-bearing or structural walls, a Professional Engineer’s endorsement is generally required to ensure the work complies with BCA structural guidelines. HDB flat owners will also need to apply for a renovation permit before coring works commence, and condominium owners should check with their MCST for any additional approval requirements. We’re familiar with these local requirements and can guide you through what’s needed for your property type.
Frequently Asked Questions
What is core drilling used for? | Core drilling is used to create clean, precise holes in concrete and masonry for piping, electrical conduits, air-conditioning lines, and other building services. |
How is coring different from hacking? | Coring uses diamond core bits to cut precise holes with minimal vibration and dust, while hacking involves breaking away larger sections of concrete. |
Can you core through reinforced concrete? | Yes, our equipment is capable of coring through reinforced concrete, though we assess each site beforehand to plan the safest approach. |
Is core drilling noisy or disruptive? | Core drilling produces significantly less noise, vibration and dust compared to traditional hacking methods, making it suitable for occupied buildings. |
What sizes of core holes can you drill? | We can drill a range of core hole sizes depending on your project’s requirements, from small utility openings to larger installation holes. |
