    Geoff’s birthday treats!

    We recently celebrated a special birthday of Geoff Davis, in a place that is close to his heart: the East Devon coast.He treated us to his knowledge of the geology and landslide systems in the area, and we treated him to an ice cream on the beach!

    Large Retaining Wall, Devon

    As part of the redevelopment of an existing large, residential property in Chagford, Devon, a large retaining wall was proposed. Ruddlesden geotechnical were commissioned to undertake a geotechnical investigation and to provide characteristic parameters for design of the wall. Ruddlesden geotechnical also provided on-going support during construction and inspected the retaining wall excavations to confirm that the ground conditions were as anticipated.

    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.
