    Validation Testing in Somerset to Satisfy NHBC and Local Authority

    Ten years after carrying out the original contamination investigation and assessment, Ruddlesden geotechnical returned to the site to carry out the validation testing of the remedial works. The validation testing included hand-excavated trial pits in garden areas, to obtain samples for laboratory testing to confirm the cleanliness of the capping soil in garden areas and to provide a photographic record of the depth of the capping layer, as well as documentary evidence of the gas protection measuresand upgraded water supply pipes. The site visit was attended promptly and the laboratory testing was expedited, following which the report was issued without delay, to ensure they were no problems with sales.

    Pile Mat Design, Plymouth

    Geogrids were used as part of a pile mat design for a site in Plymouth. Calculations, which were undertaken in accordance with BRE 470: working Platforms for Tracked Plant, showed that a significant reduction in the platform thickness could be achieved if geogrid was incorporated into the platform construction, reducing the temporary works costs. Calculations were carried out for geogrids of varying tensile strength so that cost-benefit analyses could be carried out.
