Dynamic Compaction (DC)

Dynamic compaction (DC) is soil improvement method that impose high energy on ground by applying heavy weight repeatedly tamping using different pounder weight up to 25 tons from height up to 30m. The technique concept is applying low frequency tamping and high energy.

The impact of the weight fall creates two types of waves; P wave and S wave causing densification of soil. Dynamic compaction is widely used on cohesionless soils with margin permission of fine content up to 30%.

This soil improvement method is widely used in open areas for global treatment.
The depth of improvement can reach up to 10m below ground level with total cautious in case ground water level exists.

Like all compaction techniques, the dynamic compaction technique is designed through trial area on site by calibrating the energy needed to achieve the target design criteria (bearing pressure, foundations’ settlements, and liquefaction). The calibration mainly determines the grid spacing between DC prints, number of drops, pounder weight and height of fall.
