Sediment Control - Fiber Rolls

Fiber rolls, commonly called rice straw wattles, are a very effective sediment control measure. Straw wattles are typically used in sediment control applications around jobsites, often replacing silt fence.   Straw wattles are also proven effective as Slope Interruption Devices, (SID’s). Tests done at San Diego State University show that properly installed Earthsaver™ Straw Wattles provide up to 58% reduction in the loss of sediment on the test slope.

Rice straw wattles, when properly installed, reduce the rate of water flow, absorbing water and filtering sediment. A significant amount of sediment will drop out of the water behind the wattle during a rain event. On steep slopes, wattles used in conjunction with a properly designed and installed erosion blanket results in an extremely effective BMP. Rice straw is naturally biodegradable, enhancing the soil and helping vegetation become established. The rice straw used in the Earthsaver™ straw wattles is certified weed free by the Department of Agriculture.

Earthsaver™ wattles come in a variety of sizes. The standard is 8"-8.5" diameter, with 12” and 20” diameters available for more severe applications. Rice straw wattles are contained by photodegradable netting which is designed to last at least two construction seasons. Also available is a 100% biodegradable version with burlap netting for installations with environmental concerns.

Earth Savers

Excelsior Logs are available in 9”, 12” and 18” diameters.  Excelsior Logs perform a filtering function.  These products are a non-food source and are weed free.  Excellent when used as check dams, site perimeter protection and to break up the slope length.

Western Excelsior EXCEL Aspen Excelsior Sediment Control Logs & Wattles

Coir Fiber Logs.  Coir logs are manufactured using coir fiber that is very fine.  Normal density is 7 lb/cubic foot and 12” diameter.  This log will last on a construction site three or more years.  This product is frequently used for stream, pond or river bank protection.  Aquatic plants are normally planted in the log and the root structure takes over the erosion protection job as the log biodegrades.
