In a soil grouting agent injection region surveying method for use in surveying the grouting agent injection region in a soil stabilisation process at least two electrodes are arranged in the area to be surveyed and the resistance of the soil therebetween measured. In the arrangement shown rods (Q,R) carrying electrodes (1 to 8) are positioned in the soil spaced from a chemical grouting opening carrying an electrode P. A potential is applied between the electrodes and changes in the resistance determined to obtain the extent of stabilisation of the soil. A chemical grouting pipe assembly including a swivel joint may be provided with an electrode. Alternatively two earth augers can carry the electrodes. <IMAGE> |
