Ground Investigation

Good quality ground investigations develop an understanding of anticipated ground conditions and ensure that project constraints and costs can be identified and allowed for early on.

All work is carried out in accordance with current legislation and best practice, including BS5930, BS10175, BS1377, CLR11 and Eurocode 7.

Ruddlesden geotechnical specialises in this field and utilises a full range of exploratory techniques.

Case Study

Multiple Ground Investigation Techniques on Site in Cornwall

A combination of trial pits and dynamic sampling (windowless sample boreholes)with in-situ and laboratory testing has been undertaken as part of an ongoing ground investigation for a large residential development on the outskirts of Newquay, in Cornwall.

The trial pits have allowed in-situ soakaway testing to be undertaken in accordance with BRE DG 365, to provide information for surface water drainage design.

The boreholes have allowed in-situ standard penetration testing (SPTs) to be carried out, to provide information for foundation and retaining wall design. The boreholes have also been used to install monitoring wells for long-term gas monitoring.

Both the trial pits and boreholes have been used to obtain representative samples for both contamination and geotechnical assessment purposes, which has included earthworks testing for the re-use of site-won soils.

Ruddlesden geotechnical’s knowledge of the ground conditions on this site has enabled the most suitable and cost-effective method of investigation to be used.
