Fiber Roll
A fiber roll is a temporary erosion control and sediment control device used on construction sites to protect water quality in nearby streams, rivers, lakes and seas from sediment erosion. It is made of straw, coconut fiber or similar material formed into a tubular roll. Installation Each horizontal contour level row of fiber rolls is installed on slopes, ending with one at the base of the slope, below an active construction area before soil disturbance (earth moving) begins. The space between each row of fiber roll is dependent on the steepness of the slope. The steeper the slope, the more rows of evenly spaced horizontal contour level fiber rolls are used. Each fiber roll is installed on a horizontal contour level in shallow trenches 2 to 4 inches (5 to 10 cm) deep and fastened to the ground with wooden stakes. Properly installed fiber rolls are effective at trapping sediment, generally more effectively than straw bales.U.S. EPA"National Menu of Stormwater Best Manage ...

Fiber or fibre (from la, fibra, links=no) is a natural or artificial substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene. Synthetic fibers can often be produced very cheaply and in large amounts compared to natural fibers, but for clothing natural fibers can give some benefits, such as comfort, over their synthetic counterparts. Natural fibers Natural fibers develop or occur in the fiber shape, and include those produced by plants, animals, and geological processes. They can be classified according to their origin: *Vegetable fibers are generally based on arrangements of cellulose, often with lignin: examples include cotton, hemp, jute, flax, abaca, piña, ramie, sisal, bagasse, and banana. Plant fibers are employed in the manufacture of paper and textile (cloth), and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
