One of the best methods on the market for water management and erosion control is the
Erosion Control Sock developed by Light Green Rocks Distribution. This filtration sock is a polyethylene netting filled with Expanded Shale. When laid, it will separate water from silt, sand and other runoff contaminates such as oil, grease and heavy metals.
Light Green Rocks was recently contacted by the City of Salmon Arm to replace their straw erosion control socks which had become saturated after less than one year. Rob Hein of Salmon Arm credits the new Expanded Shale
Erosion Control Socks stating “the socks have worked very well”.
