The conventional Dynamic Compaction has been processed by utilizing repeated applications of the impact delivered by a large mass weighing from 10 to 50 tons and giving them a free fall from the top. Normally 10-30 meters of height is required to create high energy waves within the ground to achieve a desired friction grip and densification on the ground.
This type of working method is somewhat not an accurate way of reaching to appropriate densification but anyways it happens until these days.
The overall design of the treatment should be in accordance with the total energy imparted to soils per square meter on site.
This technique is just fit for application to granular soils rather than cohesive soils because the sandy soils can easily lose and liquefy their friction grip each other.
It fills and serves to improve the bearing capacity and ground settlement for the foundations of civil constructions, embankments and where loose soils can be improved to render them serviceable.
Dynamic Compaction is benefitted for the foundation providing a very economical working method.
