Concrete core drilling is an essential method for creating precise, clean openings in concrete structures.
Our services cover all major core drilling techniques, including Standard Wet Core Drilling, Stitch Drilling, and Upside‑Down Core Drilling.
Standard Wet Concrete Core Drilling
Our standard wet core drilling method delivers accurate, smooth holes through reinforced concrete, brick, and masonry. This technique is ideal for a wide range of construction and engineering applications.
Key Applications
- Utility Installations: Creating openings for plumbing pipes, electrical conduits, HVAC ducting, and communication lines.
- Structural Modifications: Installing anchor bolts, sleeves, and other systems required to secure machinery or structural columns.
- Core Sampling: Extracting intact concrete samples for geotechnical testing, including density, strength, and structural integrity assessments.
Stitch Drilling (Stitch Coring)
Stitch drilling is used when large or irregular openings are required. By drilling a series of overlapping diamond core holes, we can create custom‑shaped penetrations in concrete, masonry, or stone.
This method is:
- Quiet and non‑percussive
- Low vibration, ideal for sensitive structures
- Suitable for thick or heavily reinforced concrete
- Known for producing a distinct scalloped edge
Stitch drilling is commonly used for doorway enlargements, ventilation openings, and structural alterations where saw cutting is not feasible.
Upside-down Concrete Core Drilling (Inverted Drilling)
Upside‑down core drilling—also called inverted drilling—is a specialised technique for drilling from the underside of a slab or structure. It is essential when top‑side access is restricted or impossible.
Typical applications include:
- Ceilings
- Bridges
- Tunnels
- Elevated slabs
This method allows safe, controlled drilling without compromising the structure above.
