Why Compaction is Required

ASTM D6462-03

Recently updated in 2003, ASTM D6462-03 on silt fence materials and installation requires compaction to be at least 50% of the insitu soil. To facilitate compaction, the specification also better defined the trench to be level full after compaction. (Click here to read ASTM D6462-03) As this updated specification is implemented, trenching will become economically unfeasible.
