Dynamic Compaction - 4 Pages
The Dynamic Compaction Technique
achieves deep ground densification using
the dynamic effects of high energy
impacts resulting from the drop of large
pounders. The technique was invented
and developed by Mr. Louis MENARD. Since
the early 70's, GEOPAC has applied this
technique to thousands of sites for very
different types of structures and conditions^
(port and airport platforms, heavy storage,
The basic principle behind the technique
consists in the transmission of high energy
waves through a compressible soil layer in
order to improve at depth its geotechnical
properties. Dynamic Compaction is usually
associated with an intensive in-situ testing
program in order to verify that the requi-
red improvement has been achieved.
Dynamic Compaction is applicable in any
type of granular soils. This technique is
particularly well-adapted to non-organic
heterogeneous fill, made ground and
reclamation areas with variable charac-
teristics, even with the presence of large
blocks. Dynamic Compaction is effective
in both unsaturated and saturated soils
below the water table.
