A quiet, non-percussive way of forming holes from 6mm-1200mm in diameter in reinforced concrete structures. The result is free from spoiling and requires no or very little reinstatement, with water control being used in highly sensitive areas.

Stitch drilling can be used to form large or abnormal sized openings in walls and floors. Stitch drilling entails a series of 107mm diameter holes over-lapped by approximately 10mm to form the required shaped opening. This method can also be used to create larger diameter holes of 1.0m and greater.

Diamond drilling motors vary in size and power depending on the diameter of the hole required. Drills can be powered by several different power sources, including: 110 volt electric, 3-phase high frequency electric or hydraulic motors which can be driven by either petrol or diesel power packs.

There are also various types and sizes of drilling rigs that can be used. Ranging from a hand-held machine for small diameter holes to the latest in technology with our 3-Phase High Frequency Rigs for larger diameters.
