The shallow geology beneath Ipswich is dominated by the complex interfingering of glacial till, sands, and gravels left by the Anglian glaciation, overlying the Crag Group and, eventually, the Chalk bedrock. Mapping these transitions is not straightforward. A borehole gives you a point; a resistivity survey gives you the full transect, revealing where dense boulder clay gives way to water-bearing sand lenses that can surprise an excavation crew. Our vertical electrical sounding (VES) programmes cut investigation time by targeting the interfaces that matter: the top of rock, the base of made ground, or a suspected contaminant plume migrating through the Orwell terrace gravels. In a town where river terraces meet glacial deposits, guessing the stratigraphy is a budget risk few projects can absorb.
Resistivity profiling in Ipswich's glacial terrain exposes the hidden sand channels and clay lenses that boreholes alone often miss.
