Something good just got better (a little family competition never hurts).
Switchgrass Filter Sock is much lighter than a Compost Filter Sock of similar diameter. This allows for all sorts of efficiencies (see below). The biggest one – you can put down more sock each day. This is important for large projects where E&S crews have to keep up.
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).
Other Benefits
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.
