About this detail

The geotextile fabric is secured to two-inch by two-inch wood, steel, or equivalent fence posts spaced at a maximum of six feet, which can be increased to eight feet when wire backing is used. Standard strength fabric requires a two-inch by fourteen gauge wire or equivalent for support. Joints in the geotextile fabric are spliced at posts and attached using staples, wire rings, or equivalent fasteners. The bottom of the fabric is anchored in a minimum four-inch by four-inch trench backfilled with native soil or three-quarter-inch to one-and-a-half-inch washed gravel.
