Looking into subsurface voids and how we compile data to help the planning of effective investigations
Subsurface voids (whether naturally occurring or man-made) and associated areas of soft ground present a significant risk to future, and existing, infrastructure and buildings. Unknown voids can be discovered during construction and can cause hazards and expensive delays to a project. The use of ground-penetrating radar (GPR) can be effective in identifying small or shallow voids in structures or ground up to 5 m in depth. Detailed analysis of microgravity readings can identify the size and shape of voids and is the primary method of void detection, particularly for locating deeper voids.
RSK Geophysics can assist in the detection of unforeseen and unknown buried structures such as tunnels, shafts and basements. Often, records showing the location of features are inaccurate. RSK Geophysics can help better define their location to help reduce the risk on-site.
