Silt Fence Installation

Installation primarily refers to how it is installed in the ground. There are two generally accepted methods – traditional trenching, and static slicing. Environmental Protection Agency (EPA) co-sponsored research concluded slicing was a very consistent, dependable installation. Trenching was found to have vague specifications and generally performed poorly, but improved when the trench was over-backfilled and compacted. These elements have now been included in the revised ASTM standard.
If a silt fence can not be mechanically installed (sliced in), then it is not a proper placement area for silt fence. Generally, either the space is too small or too steep for ponding to occur, and thus not the right BMP.

Mechanical installation does not excavate soil and leave the spoil dispersed, provides consistent and dependable silt fence installation, and reduces many labor-related installation problems.
