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. As this updated specification is implemented, trenching will become economically unfeasible.
I’ve had the tommy™ for five years now, and never had any problems on my sites, even with the stringent North Carolina regs. We run a couple of different companies, but with the tommy™ I can send out a relatively inexperienced crew and still get great looking fence. It gives us a very professional look with tight, non-sagging fence.
