Fiber Roll Installation and Entrenchment Detail

Materials

About this detail

Fiber rolls with a minimum diameter of 8 inches are installed along level contours on a slope, anchored by 3/4-inch by 3/4-inch wood stakes at a maximum 4-foot spacing. The rolls are entrenched into the slope with a minimum 2-inch depth and secured vertically. Adjacent rolls in a row must overlap rather than abut, with ends turned up-slope to prevent runoff bypass. Vertical spacing measured along the slope face ranges between 10 feet and 20 feet.
