Erosion Control Wales are organic filter tubes comprised of an open weave, mesh tube that is filled with a filter material (compost, wood chips, straw, coir, aspen fiber, or a mixture of materials). The tube may be constructed of geosynthec material, plasc or natural materials. Organic filter tubes are also called fiber rolls, wales, mulch socks, and/or coir rolls. Filter tubes detail the flow and capture sediment as linear controls along the contours of a slope or a perimeter control down-slope of a disturbed area.
