Cross-Hole Verification of the Effect of Grouting for Ground Improvement

The Applied Geophysics Department at Orbis Terrarum has developed a technical article analyzing the results of a study using Cross-Hole tests as part of a stabilization project for a railway embankment where differential settlements were observed.

Cross-Hole for Slope Stabilization

The objective of the study was to investigate the embankment and its foundation from a dynamic behavior perspective, quantifying the improvement achieved by calculating dynamic moduli before and after grouting.

Two Cross-Hole seismic measurement campaigns were carried out: one prior to the injections and another after execution. Six (6) boreholes were drilled to evaluate the efficiency of the grouting treatment by comparing the dynamic moduli of the embankment.
