GROUTING CONTROL BY ELECTRICAL GEOPHYSICS: FINAL REPORT OF MODEL AND PROTOTYPE STUDIES
Changes in electrical resistivity of soil resulting from injection of grout have been measured and found to provide indications of the extent of grout penetration in both the vertical and horizontal directions. Electrodes attached to a special tube-a-manchette injection pipe above and below grout injection ports provide a means for measuring soil resistance. Measurements taken along the pipe prior to grouting are compared to those taken during and after injection to define the vertical grout movement. Measurements from similar electrodes on adjacent grout pipes are used to monitor horizontal group permeation. The technique was devised from laboratory model experiments, and preliminary tests have been conducted in the field.
