Wattles installed on flat surface as perimeter control or inlet protechion may not require an anchor trench and can be secured directly to the ground surface.
Prepare site by removing debris and obstructions and minimize disturbances to yeild a smooth, even ground surface. If seeding is required, place seed, as specified, prior to instllation of wattles
Determine if an anchor trench is required. Based on site specific characteristics and product properties. Map out placement of wattle to determine location and profile of anchor trench
A one foot overlap, directed up-gradient is recommended for most products; however abutting and securing with a common stake is recommended for more porous wattles.
For channel applications, the wattle should be placed across the width of the channel and perpendicular to the center line of the channel. The wattle must to installed suffiently up the channel banks to prevent flanking or concentrated flow around the ends of the wattle
Secure the wattle with stakes or pins along the length of the unit. Stakes should be driven in vertically, perpendicular to the ground. An optional method is to drive stakes on both sides of the wattle and lace rope between the stakes holding the wattle tightly to the slope.
For slope applications, the terminal ends of the wattle should be turned 45 degrees upslope and secured by stakes to prevent water flow around the terminal ends of the wattle.
For trenched wattles, place soil on up-slope side of the wattle and compact it well. The compacted soil is placed to act as a sealant for the wattle and soil to prevent erosion from starting under the wattle.
