Abstract
A Composite Filter Sock Assembly includes a Compost Filter Sock and Secondary Tubular Seam Filling Device configured to be wedged beneath the compost filter sock, whereby the compost filter sock provides a pinning pressure to the Secondary Tubular Seam Filling Device and wherein the compost filter sock has a nominal diameter of 2-12 times a diameter of a tubular element of the Secondary Tubular Seam Filling Device. The Tubular Element may be least partially filled with a swell-able material such as sphagnum peat moss and may include a fastening mechanism on an exterior surface configured to facilitate coupling to a mesh tube of a compost filter sock.
