Minshafts and archaeology might might not be a regular combination but they both cropped up on a site in Tyneside when Phase Site Investigations carried out a magnetic survey.

Phase SI carried out a GPR survey along a 300 m stretch of carriageway in Northumberland to check for features that could be causing localised subsidence.

Phase SI has been assessed and have had their Health and Safety procedures confirmed as being CHAS compliant and congratulations to Nikki for passing the NEBOSH General Certificate in Occupational Health and Safety.

Microgravity and GPR were used to check for additional voids after a major city centre road collapse.

Microgravity, electromagnetics (EM) and resistivity imaging were used to successfully map solution features, geological variations and voids at a site in North Yorkshire.
