Concrete core drilling results in a precise, circular hole in brick, asphalt, precast concrete, concrete and many alternative structural materials. Diamond drills allow us to create holes up to 500mm in diameter in structures with a range of orientations like floors, ceilings and walls. These core holes are required for a variety of purposes like plumbing, heating, electrical wiring, air conditioning services, phone lines, data cabling, manhole taps, water pipes, computer lines, fibre optics and sprinkler systems.
