Dynamic compaction (DC), also known as dynamic deep compaction, was advanced in the mid-1960s by Louis Menard. The process involves dropping a heavy weight on the surface of the ground to compact soils to depths as great as 12.5 m. The purpose of this method is to reduce foundation settlements, reduce seismic subsidence and liquefaction potential, permit construction on fills, densify garbage dumps, and reduce settlements in collapsible soils. This method is most effective in permeable, granular

Dynamic compaction is a ground improvement technique that densifies soils and fill materials by using a drop weight. The ground is subjected to repeated surface tamping using a heavy steel and concrete weight. Typically the tamper weighs between 10 and 12 tonnes, dropping in free fall from heights of up to 10 metres. | Civil Engineering&Architecture
