Rotary Borehole Rig Craned-In, in Devon

Rotary cored boreholes were undertaken as part of a geotechnical investigation for the proposed retaining wall in North Devon.

Restricted access meant that the drilling rig had to be craned onto the site.

Cores of the rock were recovered and logged by our engineering geologist to confirm the strength, composition, and state and geometry of discontinuities within the bedrock, for use in the design of the proposed retaining wall, which was supporting a public highway and required to facilitate the development.

Downhole geophysics was subsequently undertaken to provide further information on the fracture orientation and in-situ condition.
