About Lesson
Brush layering
•Brush layer is a layer of plant material intercepted between layers of soil on cut slopes or fill slopes.
•Made of live cuttings planted in line, on terraces across the slope, covered with soil.
•Re-vegetation technique, combines layers of dormant or rooted cuttings with soil.
•Brush layers act as live fences to capture debris moving down the slope.
•Primary use- to minimize bank erosion & additional use – enhance aesthetics.
•Works better on fill than cut slopes because of the use of longer stems infill.
•Used to stabilize a slope against mass wasting & erosion protection.
