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 purchased the tommy™ in 1997 as I anticipated potential growth of the erosion control industry. We’ve grown by leaps and bounds since then, and the tommy™ has led the way. We run the heck out of it and it just keeps working. It goes into very hard ground and doesn’t take much H.P. It’s also important that we can use it on different equipment, which really gives us flexibility.
