1) Dynamic Compaction
Dynamic compaction involves lifting and dropping a heavy weight several times in one
place. The process is repeated on a grid pattern across the site. Trials in the UK indicate
that the masses in the range 5 to 10 tonnes and drops in the range 5 to 10m are effective
for compacting loose sand but not clay. Masses up to 190 tonnes and drops of 25m are
used by TLM (Technique Louis Ménard) in France. Such heavy compaction causes
fractures through which water can flow. This, according to the proponents of the system,
enables fine-grained soils to be compacted. Heavy compaction tends to annoy the
neighbours, which limits its use in built-up areas.
