Wattles (logs) are tubular erosion and stormwater runoff control devices, typically used on slopes and inclines or around construction sites. Wattles can also be used to stretch across storm drains to prevent sediment runoff into storm water systems. Due to permeability requirements for most sites, a majority of the wattles are made from natural fibers. As they filter water, they will retain sediment and enrich the surrounding area. Wattles assist in stabilizing construction disturbances by shortening the slope lengths, reducing water flow velocities and trapping sediment on site. These weed free, biodegradable wattles are made of coir fiber, straw, wood fiber and synthetic materials. They are great for unexpected floods or in construction with excessive runoff. Some types are available by special order only and not available for ordering online.
