Dynamic compaction

Method of increasing soil density

Dynamic compaction is a method that is used to increase the density of soils when certain subsurface constraints make other methods of soil compaction inappropriate. The process involves dropping a heavy weight repeatedly on the ground at regularly spaced points, usually laid out in a systematic fashion such as a grid. The weight and the height from which it is dropped determine the force delivered to the ground surface and thus the amount of compaction that occurs. Depending on the degree of compaction desired, the weight may vary between 8 and 36 tonnes, and the height between 1 and 30 metres.
