Techniques – Rock rolls and pre-planted coir rolls

Rock rolls are multi-functional and can either be used by themselves or in conjunction with the A.G.A Groups pre-planted coir rolls. Rock rolls provide a simple yet substantial solution to erosion problems, providing a solid revetment which will act to reduce sediment movement. When used in conjunction with the pre-planted coir rolls they provide a base to anchor the coir to which helps stimulate root growth and control erosion.
