Core Drilling techniques are applied when precise, circular diameter cuts are needed.  Sizes of holes are ranging from diameter 10mm to 1000mm.

Technical Specification:

• Core Hole Diameter: 10mm – 1000mm
• Core Hole Depth: Above 10 M
• Core Inclined Hole: Angle ranges from +90C to –90C

Stitch Coring is an effective method for removing almost any thickness of concrete where other methods cannot be applied.  Core holes are drilled in a series of overlapping holes, allowing for one large segment to be removed.

Typical Application:

• Holes in reinforced concrete, pre-cast concrete, brick, block, asphalt and many other structural material
• Underground utilities construction: phone, electrical & plumbing lines
• HVAC duct
• Fire sprinkler installations
• Floor drains & sewer drains
