As I have written in previous posts, compost socks make excellent perimeter berms, especially when used on impervious surfaces. Make sure to overlap the ends and don’t drive over them. Recycle the compost when done.

We used to use silt fence when we did construction on the airfield. More and more we are using compost berms. The airfield grades are very small, maybe 20:1.

Compost berms can contain bare soil areas, filtering turbid water. When complete, we spread the compost and hydroseeded.

We rarely use silt fence on smaller airfield projects because: the work areas are nearly flat, are surrounded by grass or pavement, the work takes a few months, usually in the summer or fall. Compost berms are frequently used to: contain water, divert water, prevent site runoff. A secondary benefit is filtration; there is some turbidity reduction. Lastly, when done,. we spread the compost out over the disturbed soil and hydroseed it, enhancing grass growth and eliminating the waste of land-filling silt fence.
