Integral to all buildings are their foundations and knowing their construction can help determine why structural defects above ground may have occurred.
GBG provide geotechnical investigations to determine existing ground conditions, geology and details of sub-surface structures and foundations through trial pits, boreholes and passive survey techniques.
Geophysical surveying comprises the collection of data for spatial studies relating to the subsurface. This provides answers / solutions to various industries who are involved in construction within the subsurface. It can also be used for hazard mapping of underground features such as sinkholes and solution features associated with the chalk landscape of southern England. The applications can equally be used to map mining hazards from abandoned shafts.
GBG investigates a wide range of structures from historically significant buildings to small private residences.
