Ruddlesden geotechnical

Ruddlesden geotechnical provides ground investigation, geotechnical consultancy and contamination assessment services.

Based in Exeter, but covering the whole of the UK, albeit primarily concentrated in the South West, Ruddlesden geotechnical was formed in 2004.

Ruddlesden geotechnical works on behalf of a wide client base, including local, regional and national housing developers, housing associations, commercial developers, building contractors, structural and civil engineers, architects, building consultants, quantity surveyors, local authorities and private individuals.

    Creative geotechnical photography

    Inspired by her surroundings at RHS Rosemoor, where she was carrying out the ground investigation for a new educational facility, and with one eye on the Ruddlesden geotechnical site photograph of the year competition, Catherine Greed got creative with her site photography recently, framing the dynamic sampling rig within the last of the summer flowers.

    Cable Percussive Boreholes for Piled Foundation Design and Settlement Analysis

    Cable percussive boring was undertaken as part of a geotechnical investigation to determine the ground profile for piled foundation design and assess the settlement of soft and compressible ground beneath a proposed embankment at the site of a proposed residential development in Shropshire. Cable percussive boring was considered the most suitable method for this project as they facilitated the recovery of relatively soft soils to depths of up to 20m, which could not have been achieved using dynamic sampling/ windowless sample boreholes, trial pits or conventional rotary boreholes. In addition to facilitating in-situ standard penetration tests (SPTs), the cable percussive boreholes allowed undisturbed samples to be taken for undrained triaxial and oedometer consolidation laboratory testing to be carried out, for foundation design and settlement analysis.

    Asbestos Testing Allays the Concerns of Locals

    As part of a larger contamination investigation and assessment for the residential development of a former power station, asbestos testing was undertaken. Anecdotally, asbestos containing materials (ACMs) arising from the decommissioning of the former power station had been encapsulated in a buried concrete chamber. Concerns were raised by locals and the local authority about how safe this was and whether the proposed development would endanger the general public, end users and construction workers. Intensive asbestos investigation and assessment, undertaken in accordance with the Control of Asbestos Regulations (CAR, 2012) and which included asbestos quantification testing, identified that the proposed remedial strategy to mitigate other contaminants at the site, which included raising the site levels and capping with inert soil, would also protect from the low levels of asbestos recorded in the soil., with no further measures required protect end users. The asbestos testing also enabled safe methods of working to be determined for construction workers.
