Installation on Slopes>> More
Place KoirWattle along horizontal contour of slopes in 2" to 4" deep anchor trenches (see Fig 1). Successive rows of KoirWattle can be placed 10’ to 20’ apart. Drive 1" x 1" x 24" hardwood stakes every 3’ to 4’ on center through the middle and ends of each KoirWattle. Place KoirWattle end to end tying ends together securely with KoirTwine or BioTwine. The selection of trench depths and the placement of stakes depend on the slope and soil conditions. KoirWattle should always be placed and secured such that water flows through or over the KoirWattle and never underneath.

Installation in Channels
Place KoirWattle in 2" to 4" deep anchor trenches across the channel perpendicular to the direction of the flow (Fig 2). Use 1" x 1" x 24" hardwood stakes at 2’ to 4’ intervals on centers and 1’ maximum from either ends to secure the KoirWattle. If two or more KoirWattles are used across a section, place KoirWattles end to end and tie the ends together securely with KoirTwine or BioTwine.

Installation Around Drop Inlets and Curb Inlets
Place Koirwattle around drop inlet and curb inlet in such a way that there is no space between the ends of the KoirWattle. (See Fig 3 and Fig 4 respectively.) KoirWattles must be secured to the ground using 1" x 1" x 24" hardwood stakes at 2’ on center. The top surface of the KoirWattle must be located above the ponding height. Use multiple tiers if necessary.
