Cable percussion drilling is the UK’s most common form of drilling for standard geotechnical and ground investigations. Boreholes are formed using a shell or clay-cutter (the drill bit which is used depends entirely on the formation being bored into). Then, as the percussive drilling progresses, steel casing is lowered into the borehole to ensure the integrity and stability of the surrounding borehole walls. One of the main benefits to cable percussion drilling is that it can tackle most types of ground situation, both consolidated and unconsolidated substrate formations. Cable percussion drilling can also drill deeper, and drill further into the water table than other drilling methods.
our crew & process
A cable percussion crew consists of two fully NVQ trained operatives, one lead driller and an additional support operative. Our drilling operatives also have various certifications such as SSSTS, cable avoidance, first aid training, etc. The image to the right shows one of our cable percussion crews in full flow.
The rig is typically towed into position using a four by four vehicle, and is subsequently erected into the correct position via an electronic winch . To avoid any potential service disruptions, hand pitting is also carried out beforehand.
At Borehole Solutions Ltd, our fleet of Cable Drilling rigs are widely used on various public, private and governmental construction projects. Each crew typically also carries with them a tablet and mobile printer, so that logging can be performed on site, we can provide logging in PDF and AGS format for importation into systems such as Holebase etc.
