ABSTRACT:
A fiber block segment suitable for controlling erosion and stabilizing soil is described that comprises an elongated fiber block formed of a densely packed elongated thick fibrous material. The fiber block is wrapped with a fabric around three sides so that the fabric defines a top anchor portion and a bottom anchor portions extending from the block. The fiber block is securely attached to the wrapped fabric by another fabric or twine spanning the fourth side of the block. Additionally, the fabric is wrapped only up to the edges defining one end (a male end) and beyond the edges defining the opposite end (the female end) to define a pouch-like structure at the female end. The fiber block is made of coconut fibers (coir). The fabric is woven from coir twine, and coir twine secures the fabric to the fiber block.
