The non-destructive GPR-method detects material changes, changes of compactness and disturbances of the grain structure with high accuracy in position and depth. Thus potential zones of weakness as fractures or voids can already be detected  at an early stage.

CAD-results map containing site map and cross-sections from longitudinal and cross profiles

The combination of longitudinal and cross profiles adds up to a virtual three-dimensional view. The knowledge of the sterical geometry of the dyke body is an essential precondition to evaluate the stability.
