Before we drill any boreholes, it is recommended that checks are made to see if planning consent is required from your local planning authority. In the majority of cases, planning consent will already exist under permitted development provisions. Sometimes however, local restrictions may apply if, for example,. .

(Image: Water coming from borehole) We require and use water during the drilling process (we do need you to have a good water supply for our use), we will almost always hit water whilst drilling at some point / depth. The volumes involved can be considerable, as. .

(Image: Sump filled with spoil) In addition to water, the drilling will produce a wet aggregate of broken rock and soil from the borehole – generally about 1.5 tonnes of aggregate per 100m of depth. Unless otherwise stated, disposal of this spoil is the responsibility of.
[pdf] Geotechnical drill rigs are specialized equipment for the rigorous demands of construction and geological projects. These rigs play a key role in geotechnical investigation, providing the capability to assess ground conditions.

Mobile offshore drilling units (MODU) Semi-submersible rigs make stable platforms for drilling for offshore oil and gas. They can be towed into position by a tugboat and anchored, or moved by and kept in position by their own azimuth thrusters with dynamic positioning. The International Maritime Organization. .
