3D Geophysics Data Plot

TerraDat is a European leader in state-of-the-art non-invasive Geophysical Site Investigations, Geological Mapping and 3D Geodetic Laser Scanning.

We have extensive experience in all areas of subsurface mapping in relation to the Geotechnical, Civil Engineering, Environmental Waste Management, Groundwater and Mineral Industries

Our services are used by public sector and commercial organisations to gain an in-depth understanding of the subsurface to reduce the risk of exposure to buried hazards and optimise budgets.

In addition to our geophysical survey capabilities, we have a specialist survey division for creation of 3-dimensional models using photogrammetry. Applications include heritage building models, forensic crime and accident scene reconstructions and geotechnical mapping.

TerraDat is part of a team of scientists who have been monitoring the melting of permafrost in Europe’s alpine regions for the E.U. and Swiss Government in a research project called PACE, Permafrost and Climate in Europe. The experience and innovations developed in this project are available commercially through TERRADAT and its associates.

Given that temperatures in the permafrost layer is only -2 or -3 deg. C, it will not take much warming to cause a melt. The combination of ground temperatures only slightly below zero, high ice contents and steep slopes, makes mountain permafrost particularly vulnerable to changes.

GPR profiling in the Alps to map permafrost interface		The likely consequences of degrading permafrost would be an increase of slope failures, mudslides and rock falls. There are some frozen rock slopes that are so unstable they can fail even before a thaw. The effects are likely to be most disastrous in the Alps where steep slopes mean villages, roads and railways are built directly below altitude permafrost zones, however this can be a global problem – especially where manmade activities such as pipelines or building services artificially degrade permafrost.

TerraDat Geophysics has been independently audited and certified to be in conformance with ISO 9001:2008. This marks the latest step in our efforts to lead the field of specialist high resolution ground mapping and runs alongside our commitment to investment in the latest instrumentation, processing facilities and staff training.

The South Wales valleys have one of the highest risks of active landsliding in the UK due to a number of complex geological, landscape and historical coal mining factors.

This joint initiative explores new and innovative ways to quickly assess areas in South Wales that are most at risk from landslides.

The team are using novel techniques, such as small hand-controlled helium balloons with digital cameras and GPS controlled high resolution geophysical surveying.
