SwitchSoxx Light in weight, but not performance.
Install more filter sock each day with SwitchSoxx – a lightweight alternative to compost sock. Plus, the carefully sourced switchgrass fill promotes vegetative growth once your job is complete.
Performance matters – Independent testing shows that Switchgrass Filter Sock and Compost Filter Sock have similar hydraulic flow and sediment removal characteristics*.

Compared to Compost Filter Sock
Switch Sock is light in weight but not performance. Lay more down a day and keep up with demand.
-
Similar hydraulic flow and sediment removal rates
-
Same high-quality netting as palletized CFS
-
Stakes in kit for placement every 5 feet (CFS is 10 feet)
-
Available pre-filled diameters are 8, 12, 18, and 24 – inch
-
Palletized standard in a supersack and available in continuous or precut lengths
-
Much lower weight per pallet (650 lbs vs. 1750 lbs)
-
On average, 36% more footage per Tractor Load (1430 vs.1950 linear feet of 18 – inch).
Why Choose SwitchSoxx?
Switch Sock promotes vegetative growth better than Compost Filter Sock. Cut the sock, spread the fill and recycle the netting.
Promotes vegetative cover better than CFS fill
Can be stacked in a pyramid. Especially useful when CFS is placed on bottom rows and SGFS is placed on upper rows.
Frequently Asked Questions
SwitchSoxx is a sediment control filter sock filled with switchgrass, a natural, renewable fiber. It is designed to slow stormwater runoff, reduce sediment loss, and provide effective erosion and sediment control on construction sites and other disturbed areas.
As stormwater flows through the SwitchSoxx, the dense switchgrass fill slows water velocity and captures sediment within the sock. This process reduces erosion downstream while allowing treated water to continue flowing through the system.
SwitchSoxx is significantly lighter than traditional compost filter socks, making it easier to transport, handle, and install. Despite its lighter weight, independent testing has shown SwitchSoxx to provide sediment control performance comparable to compost-filled socks. The reduced weight also helps lower labor costs and installation time.
SwitchSoxx is commonly used along site perimeters, on slopes, as check dams in channels, and in other areas where runoff control and sediment reduction are required. Its lightweight design makes it especially useful on sites where access is limited or where frequent repositioning may be necessary.
Yes. The switchgrass fill can support vegetative growth over time, helping integrate the product into the surrounding environment and improving long-term erosion control performance.
SwitchSoxx is available in multiple diameters, including 8”, 12”, 18”, and 24”, allowing it to be selected based on site conditions, flow rates, and project requirements.
Yes. SwitchSoxx is lightweight and easy to handle, which allows for faster installation with reduced labor compared to traditional compost filter socks. It does not require trenching and can be installed directly on the soil surface. For secure placement and proper performance, stakes are typically installed approximately every 5 feet along the length of the sock to maintain alignment and stability during storm events.
Yes. SwitchSoxx has undergone independent testing that demonstrates sediment retention performance comparable to compost filter socks, while offering the added benefit of reduced weight and easier installation.
