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.

Development projects range from single dwellings and extensions to large housing estates, multi-storey flats, offices, industrial units, roads, slopes, schools, hospitals and basements.

The services and projects listed on this web-site provide an indication of those undertaken by Ruddlesden geotechnical, but others are carried out. If your requirement is not readily identifiable on this web-site, please contact us as we may still be able to help you.

    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.

    Economical Recommendations Provided for Ground Floor Slab Design, Devon

    Ruddlesden geotechnical were commissioned to review historical site investigation data to form a ground model and provide guidance on the use of a ground bearing slab for a proposed warehouse for a regional wholesaler. Consideration was given to the bearing capacity of the subgrade, volume change potential of the soil, slope of the ground, groundwater table, ground aggressivity and the presence of non-engineered fill materials. To avoid the requirement for a suspended floor slab, it was recommended that the superficial shrinkable soils be removed and engineered fill be imported to support the proposed ground bearing slab.

    Geotechnical Considerations for Basement Construction for Proposed Hospital

    For a proposed basement car park at a hospital in Dorset, Ruddlesden geotechnical were commissioned to undertake a geotechnical investigation. The geotechnical investigation indicated that a thick succession of river gravels was present beneath the site, for the base of the proposed basement. Widespread collapse of strata was observed in machine-excavated trial pits during the investigation and elevated groundwater pressures were recorded during subsequent groundwater monitoring. In light of the ground conditions encountered, it was recommended that a top-down construction approach be undertaken, e.g. using a secant bored pile wall, to mitigate the effects of collapsible ground and the need to dewater excavations. It was also considered that, depending on the weight of the proposed structure, tensioned piles might be required to resist flotation of the structure as a result of the high groundwater pressures.
