When preliminary information from previous investigations and desk top studies is complete but understanding of the ground conditions below the development site are not fully understood – Geotechnical investigation is still the first and best means of physically exploring the subsurface.
All said and done, to truly understand ground condition below your site, nothing beats the quality of information gained from the recovery of soils and rock core via boring and rock coring.

When shallow ground investigation is required trial pit and slit trench analysis provide the best means of determining soil conditions and pinpointing the location of any buried underground services.

Rather than intrusive removal of materials for laboratory testing often in- situ testing and / or non-destructive testing (NDT) offers a more beneficial and effective approach to assessing ground condition and concrete structures.

Although soils are initially identified in the field as they are recovered it is also important to schedule laboratory testing of soils in order to aid their final classification. Whiteford Geoservices undertakes a range of such soil tests to aid classification at our in-house laboratory and has arrangements with other accredited laboratories for more specialist tests should these be required.

Thermal resistivity is a lesser known property of soils and rock that has a significant impact on the performance of buried electrical cables.
