Above Piletec overcoming sandstone boulders, to mitigate vibration risks associated with traditional down the hole (DTH) equipment, we were able to utilise our heavy duty diamond drilling rigs & equipment.
Diamond Drilling
A diamond drill is a precision instrument, creating clean, accurate holes with diameters of between 10mm to more than 1500mm. As it is a non-percussive technique, structural integrity is maintained around the bore when drilling. Most diamond drills run water through the driving shaft to ensure that the workspace remains free of dust And the diamond tips are kept cool.They can be operated in any direction depending on the requirements.,
Diamond Drilling is a form of core drilling which uses a rotary drill with a diamond drill bit attached in order to create precisely measured holes. As diamond is the hardest naturally occurring material in the world, it is ideal for creating openings in a range of materials including concrete, metal and glass.
A diamond drill is a precision instrument, creating clean, accurate holes with diameters of between 8mm to more than 1500mm. As it is a non-percussive technique, structural integrity is maintained around when drilling. Every diamond drill runs water through the driving shaft to ensure that the workspace remains free of dust. They can be operated in either a vertical or horizontal direction depending on the requirements.
Although diamond drills are primarily used on concrete, it is a versatile tool that can be deployed on virtually any material including glass, metal, stone, asphalt and tile. Diamond Drilling is utilised in any situation where precise holes are required including creating large openings for ducts, smaller holes for pipes or wiring, creating holes for the placement of anchoring bolts, ground anchors or even for concrete sample analysis. Holes can be created to almost unlimited depth.
TYPES OF Diamond Drilling
Diamond core drilling 300mm diameter carried out by Piletec’s multi skilled team at Tottenham North Curve to allow access through 5m of masonry before auger drilling to 46m.

A traditional non-percussive drilling technique for strengthening bridge piers and wing walls is to Diamond Core Drill through the brick work or concrete structure.
Then to continue drilling using continuous threaded steel casings. through the infill, which is generally made up of Clay/Chalk/Railway Ballast. The main advantage of using this technique is it gives you the ability to temporary or permanently sleeve the borehole until the tie bar is fixed in place.
Piletec have adopted this technique because accuracy is a major factor when installing Tie Bars, also deflection is less of a risk.
This technique is also used by Piletec for core sampling through bridge piers and abutments.
Diamond stitch drilling is when you link single holes together to form a linear line. The holes are normally lapped by a small margin in order to maximise on the length per hole ratio to form the given line.
This method is often used on large openings to accommodate the corners between the longer saw cuts and small openings where saw cutting is not practically viable to form the opening or where access prohibits the saw cutting equipment to be utilised.
Diamond stitch drilling can also be used to form slots which is useful when forming door heads and lintel bearings, or even needle holes to accommodate the installation of temporary support prior to forming openings within load bearing structures.
