REASONS FOR COMPACTION
lead to one or more problems occurring.
3. Materials with voids are more susceptible to water seepage, leading to erosion. Water ingress may also cause the soil
to expand during freezing temperatures and contract during dry spells. Expansion and contraction is a major cause of
damage to building foundations and normally leads to the structure requiring underpinning.
Compaction increases the density of the material and therefore increases its load bearing capacity. Reduces air voids
and therefore reduces the risk of subsidence, expansion and contraction, due to ingress of water.
APPLICATIONS
Applications/materials fall into three categories:
optimum compaction can not be guaranteed, however, if layer depths are reduced and number of passes increased, results can be
improved.
the plate instead of compacting. If the moisture content is too high the material may dry out after compaction and shrinkage will occur.
