ZETICA

Zetica is the UK’s leader in engineering and environmental geophysics with an enviable reputation for objective advice, cost effective surveys, and easy to understand reporting. The company also has a standout track record for innovation with recent advances including a wireless borehole magnetometer to survey while you drill, a multi-sensor data acquisition system for multi-instrument surveys, and a train-mounted rail radar system for scanning at speeds of over 300km/h.

Company profile

Evaluating the surface potential of land assets is usually straightforward. But how can you measure possible underground liabilities? Potential problems include disturbance, erosion, poor compaction, cavities, buried channels, abandoned services, concealed working, buried hazards and unexploded ordnance. These, in addition to naturally occurring faults, folds, joints and fissures, can transform profitable prospects into costly mistakes.

Zetica offers a holistic, fit-for-purpose approach to site assessment. Our modern, cost-effective survey techniques turn complex streams of valuable data into clear images of the underground environment. This helps clients to avoid costly practical problems and maximise site potential. Zetica has extensive, global experience, working wherever an informed understanding of the sub-site environment supports engineering improvement and investment work.

Today, planners often call for an initial view of the underground environment before designing their traditional, quantitative core drilling programmes. Zetica can reveal the subterranean landscape, and identify important factors such as changes in material properties and the presence of concealed structures.
