Ground Investigation

OVERWATER GI

Central Alliance is comfortable taking on a variety of overwater ground investigations. Whether using pontoons or jack-up platforms, we are used to delivering overwater GI work safely, acquiring data where it is needed most.  Previous work has included rotary drilling, dynamic sampling, cable percussion boring and structural investigations. Work is typically in rivers, canals, lagoons, reservoirs, docks and harbours, though we also have near shore experience.
