ADDITION9896 N MICHIGAN ROADCARMEL, INDIANA 46032CONCRETE WASHOUT BMP PLAN SECTION B-B SILT SOCK SPECIFICATION Size :8” diameter Definition: A silt sock is a tubular-shaped material comprised of a fabric exterior filled with wood chips or compost. The material used in the sock is an environmentally safe material. The silt sock fabric comes in rolls of 600 – 1000 feet. The silt sock is typically laid on the top of the ground along the down-slope areas and along side-slope areas as required to contain & reduce erosion. The silt sock is either lapped or butted at the ends to create a continuous line of defense. Staking the sock is not usually required. The first water to contact the sock is absorbed “staking” the sock in place by its weight alone. In greater sloped areas the sock may be secured in place by stakes or other supports. Care and Maintenance The following silt sock conditions require maintenance: ··Deformation due to drive-over or dragging. Action required: Re-contour by hand if applicable. If not, see applicable repair methods below. ··Sock rolling due to hydraulic force. Action required: Reposition and stake. ··Loss of ground contact. Action required: Fill in depressions and back-grout with chips from damaged section. ··Sediment accumulation of ½ sock height. Action required: Remove by hand or install a second row of sock positioned on top of or up slope of the original sock The following silt sock conditions require repair: ··Holes, rips or tears of the sock. Action required: Small holes or narrow rips shorter than 12 inches may be stitched closed using plastic zip-ties. Tears longer than 12 inches require the sock be replaced. ··Pinch or localized diameter reduction of more than ½ the original diameter. Action required: Install new section of sock upslope of the damaged section. SILT SOCK INSTALLATION
