•Dynamic Compaction is the process of systematically tamping the surface with a heavy weight dropped from a height, it improves the bearing capacity of a wide range of materials, but works better in general – loose granular fill materials.
•The reasoning behind the use of Dynamic Compaction is to increase the density of materials therefore reducing the void spaces.
•Dynamic Compaction is a quick and cost effective way of ground improvement, for large open sites, such as the large colliery spoil sites.
•Dynamic Compaction as with other improvement techniques requires preliminary considerations into:
•Design Constraints such as sensitivity of the new embankment/facility, relative to settlement and bearing capacity
•Type of deposits at site to be evaluated to identify D.C.’s appropriateness.
•Proximity of existing structures/services
•Cost compared to other alternatives.
