Installation on Slopes
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 KoirWattle™s are used across a section, place KoirWattle™s 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.) KoirWattle™s 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.
