Dynamic soil improvement

Dynamic soil improvement techniques are:


– Vibro replacement

– Vibrofloatation

– Impulse compaction


All of these techniques are widely used for various reasons, such as compaction, resistance to liquefication, bearing resistance, improvement of  seepage and so on.


Basically first 3 methods are used for non-cohesive poor to medium density soils.

Impulse compaction is a recent method for soil improvement; it is a cost effective method for compacting non cohesive soils up to 4 m depth.

The other methods such as vibro compaction are most effective for sandy, silty soils.
