EMerald’s unique method is based on a three-step approach:
Traditionally, the geotechnical industry has largely relied on drillings. When no prior knowledge exists, resources are typically spent on exploratory drillings to gain an overview of the project area. Many of these are later considered redundant and add little value. The gaps between boreholes remain too large to mitigate geological risk.
Geophysical investigations have been an exception rather than a rule in geotechnical works. When they are used, the geophysical products are often delivered with little interaction with geotechnical investigations. Only a few specialized engineers can use the delivered geophysical data to its full extent. Value is lost.
Nowadays at EMerald, we use geophysical and geotechnical investigations together to unlock their true potential. Rather than confusing geophysical parameters, we deliver engineering parameters with quantified uncertainty as 3D models that are directly used in planning works. Moreover, rather than getting point-wise data at geotechnical soundings locations, we can instead get a better overview of soil properties in the project area.
