Seismic Refraction Profiling is used to investigate the seismic velocity of subsurface layers to help identify the material type, layer thickness, material stiffness and rock quality of the subsurface layers.
Ground Penetrating Radar (GPR) is an electromagnetic technique used to image the subsurface and has many applications including investigating the underlying geology, locating buried objects such as pipes and tanks and mapping peat thickness.
Microgravity surveying involves the measurement of the Earth's Gravitational Field on the earth’s surface. Density variations of the underlying geology will result in variations of the recorded microgravity readings. These density variations may be caused by features such as air, water or sediment filled cavities, or changes in the nature of the subsurface material and bedrock or in the bedrock topography.
2D Resistivity Imaging is used to investigate lateral variations in overburden material, depth to bedrock and bedrock lithology.
In the Multichannel Analysis of Surface Waves (MASW) technique, Surface Waves (Rayleigh Waves) are utilised to determine the elastic properties of the shallow subsurface (<15m).
