Silt Barrier for Drainage Ditch

I am looking for a silt barrier to prevent silt build up in a drainage ditch near our site. I know that they are usually deployed in deeper water. Do you have any ideas?

Thanks for contacting Granite Environmental! I would be happy to help you with this. You are correct that a silt barrier is usually deployed in water, but we have something that would be ideal for your need.

Our staked silt barrier is designed specifically for storm water run-off and sheet-flow control at job sites and silt & sediment control in water shallower that 30 inches such as road side ditches, canals, shallow ponds and lakes. These are excellent BMP's (Best Management Practices) for along road side ditches, shallow marshes and lakes where a floating turbidity curtain, floating silt barrier or traditional silt fence would not work well. We use the very best A-grade industrial membrane with 350 lbs tensile strength and is safety yellow in color, so it's easily located. This system can be used in water depths less than 30" and no flow. In place of back-fill use sand bags to create bottom seal.

Installation is easy too! To install this BMP, dig an 8 inch deep trench along the desired flow control path placing fill on up slope side of trench. On down slope side of trench install 1"x1" wooden stakes (re-bar of similar) on 6' centers maximum. These are to protrude 36" above the gradient.

Unroll the Silt barrier and fasten to stakes with ties - 36 inches attached to stakes and 8 inches in trench (HEMMED EDGE IS TOP). Once entire run is in place and desired flow diversion path is in place then back-fill the 8 inch trench trapping the bottom 8 inches of the silt barrier, effectively creating a runoff seal.
