Deep compaction of in-situ foundation soil by Terra probe compaction:
It is a method of vibration compaction, company named L.B. Forester patented it. In this method a vibrating pile driver is mounted on probe and treats it by vibrating in and out of the soil. For soils which can be made denser using vibroflotation, this method is quite effective. The probe used can be inserted at 1.5 to 5m centers, depending on the degree of compaction.
