Compost Filter Socks: What They Are and How They Work

Soil erosion is caused by a multitude of factors, but the main determinant is water runoff. Water runoff gradually transports topsoil, sediment, and even pollution into streams and rivers, negatively affecting its biodiversity and wildlife. Fortunately, an impactful and cost-effective way to control water runoff in areas such as gardens, construction sites, or farms is by implementing a compost filter sock. 

Compost Filter Socks

Compost socks consist of a mesh tube netting filled with compost that filters sediments, nutrients, bacteria, heavy metals, and petroleum hydrocarbons including gasoline, diesel, and oil residues. Unlike silt fences, filter socks have higher permeability that thoroughly filters water runoff while controlling sediment loss. Diamond Sock is a high-quality option that is made out of filter fabric and filled with a premixed blend of Kurtz Bros., Inc. mulch and compost. Heavy-duty compost filter socks are cost-effective and durable even performing well under extreme conditions.

Where to Place Compost Filter Socks

A compost filter sock is commonly used in landscaping and home gardening or commercial areas such as construction sites or parks. Filter socks can be installed in any downslope areas where erosion and sediment control are needed. Because filter socks are so flexible, they can also be used on paved areas, near sensitive trees, or on frozen ground. It is flush to the ground and prevents water from flowing underneath. A compost filter sock is reusable and easy to move and re-install. Moreover, it does not require trenching and does not disturb the ground in areas with established vegetation. 


An added benefit to using compost socks is that it is useful beyond its life cycle. When you no longer need your compost sock, only the mesh needs to be disposed of. The organic content in the sock is good can be added to the surrounding terrain. Besides filtering water runoff, its additional uses include:

  • Water Diversion
  • Perimeter Control
  • Slope Interruption
  • Inlet Protection
  • Ditch Check
  • River or Pond Bank Stabilization
