Compost Diversion Sock


Divert stormwater runoff, naturally.

DiversionSoxx, a conveyance BMP, replaces excavated freshwater diversion ditches.

Runoff diversion is a Best Management Practice (BMP) used to redirect stormwater runoff from areas at risk of flooding or eroding towards stabilized areas, storm inlets, conveyance systems, containment areas, or stormwater treatment systems. DiversionSoxx is a three dimensional tubular sock designed to act as a sediment control and filtration device, generally used up slope of disturbed areas undergoing excavation. In runoff diversion applications, our DiversionSoxx technology helps divert excess surface water from one area for use or safe disposal in other designated areas.

DiversionSoxx can be installed above steep slopes to limit surface runoff onto the slope, across long slopes to reduce slope length to prevent erosion, below steep grades where flooding, seepage, or sediment depositions may occur and around areas that are subject to damage from runoff.

DiversionSoxx is much heavier and denser than Compost Filter Sock, so water is conveyed along it, not through it. DiversionSoxx is placed above the job site in a diagonal orientation. Fresh water flows along (not through) DiversionSoxx and around the disturbed areas of the job site.

DiversionSoxx is used for diversion or redirection of runoff otherwise flowing to disturbed or highly erodable areas on and around construction activities. DiversionSoxx can be used as temporary or permanent runoff diversion device used to prevent soil erosion during excavation, or prior to erosion control practice installation, vegetation establishment, or final stabilization.

Runoff diversion should direct runoff flows to stabilized channels, heavily vegetated areas, on to flat surfaces, infiltration zones, collection ponds, or storm inlets. Runoff diversion can also be used for temporary diversion on paved surfaces to protect disturbed soils adjacent to paved areas.

For temporary applications, DiversionSoxx does not need to be seeded; however, for permanent runoff diversion the device should be direct seeded at the time of application, as vegetation will prevent UV degradation of the device. DiversionSoxx may also be used in sensitive environmental areas, where migration of wildlife may be impeded by the use of fences or trenching may damage plant roots.


Installed on a 5% diagonal fall, DiversionSoxx moves water away from your disturbed areas.

  • Little to no hydraulic flow through
  • 30% heavier than compost filter Sock – provides high surface contact
  • Can be vegetated as a permanent device
  • Can be adjusted/moved on the job site
  • Easier than excavating a freshwater diversion ditch – no trenching required
  • Can be installed on frozen ground
  • Can be installed on top of rolled erosion control products


Diversion Sock ships on a pallet or in a super sack to make your next freshwater diversion project even easier.

  • Available in 12, 18 or 24 inch diameters
  • Stakes included for every 5 ft
  • Available coiled on a pallet or in a super sack
  • 50% Compost Filter Sock fill plus 50% leaf compost
  • Minimum 12-diameter, 5% diagonal fall
  • Uses the same heavy-duty netting as Compost Filter Sock


  • Up-slope of disturbed areas
  • Divert sheet flow
  • Use prior to erosion control practice installation
  • Use prior to vegetation establishment
  • Use prior to final soil stabilization
  • Habitat or ecological restoration
