RoLanka offers GeoNatural™ products made of coconut fiber (coir fiber) for sediment control BMP's. Tensile strength coir fiber exceeds that of straw and excelsior (wood fiber) and jute. Coir fiber is unpalatable to wildlife, which makes them a more suitable for sediment control without causing any damage to wildlife. Geonatural™ sediment control products can be left at the site or they can be buried on site upon use. Therefore, use of Geonatural™ for sediment control is more cost effective and healthy to the environment.
