You’ll love using Big Switch® instead of the typical silt fence, straw bale barrier, wood chip or mulch socks which may be detrimental to the environment.

And the best part is Big Switch®. . .

  • Doesn’t require any trenching or disturbing the soil surface
  • Is lightweight, making it’s user friendly, easier for you to install and less expensive to ship
  • Has a huge contact surface area
  • Greatly reduces your tannic acids, heavy metals and volatile organic compounds such as arsenic
  • Doesn’t need to be removed because it dissolves easily and naturally.

Big Switch Erosion Control System

Even Better, Big Switch® has earned the U.S. Department of Agriculture (USDA) Certified Biobased Product label.

Plus, it’s Third-Party accredited verification for it’s biobased content is administered through the USDA BioPreferred Program, an initiative created by the 2002 Farm Bill (and most recently expanded by the 2014 Farm Bill).

Big Switch® proudly displays the USDA label that highlights its 100% biobased content.

The Big Switch Is Perfect For Erosion Control?

You’ll use it for preventing soil erosion and providing filtration which is critical in protecting your property and exposed soil, whether from wind, weather, running water, and even the after-effects of forest fire.

Big Switch® is light weight vs. mulch, saving you back strains, shipping cost and headaches.

Here are some erosion/filtration applications you can do with Big Switch®:

The Big Switch® Erosion-Filtration Medium is perfect for construction sites or other disturbed areas where storm water runoff occurs as sheet flow.

Common industry practice for filter devices is that drainage areas do not exceed 0.25 acre per 100 feet of device length and flow does not exceed one cubic foot per second.

The Big Switch® can be used on steeper slopes with faster flows if they are spaced more closely, stacked beside and/or on top of each other, made in larger diameters, or used in combination with other storm water Best Management Practices.


What Exactly Is The Big Switch?

Big Switch® is a non-toxic, plant-based compost that serves as a sediment filter and erosion control.

It's way more environmentally friendly than wood based products that serve the same purpose. Why, because different woods can carry arsenic in the bark which can be harmful to aquatic life. 

The products are large “socks” made out of polyethylene that is filled with a 100 percent switch grass mixture.

Once placed in the desired location, the socks can absorb up to 40 percent of its weight in moisture and then dry out relatively quickly. 


The Big Switch®, is oval to round in cross section and is designed to provide a three-dimensional medium which retains sediment and other pollutants (e.g., suspended solids, tannic acid, nitrates, phosphate’s and motor oil) while allowing the cleaned water to flow through.

It can be easily used in place of traditional sediment and erosion control tools such as a silt fence.

They are generally placed along the perimeter of a site, or at intervals along a slope, to capture and treat storm water that runs off as sheet flow.

Big Switch®  is designed to be flexible and easily moved into position, making them especially useful on steep or rocky slopes where installation of other erosion control tools is not feasible.

Even better, there is greater surface area contact with soil than typical sediment control devices, because of this, you'll reduce the potential for runoff to create rills under the device and/or create channels carrying unfiltered sediment.

And, they can be laid adjacent to each other, perpendicular to storm water flow, to reduce flow velocity and soil erosion.

The Big Switch® can also be used on pavement as inlet protection for storm drains and to slow water flow in small ditches.

Available in 8, 12, 18, 24 and 32 inches in diameter and specialty sizes are available by request. 

You also have the option or either un-vegetated or vegetated. 

Vegetated product can be left in place to provide long-term filtration of storm water as a post-construction best management practice (BMP). The vegetation grows into the slope, further anchoring the filter.

Easy To Install And Easy To Move?

Once The Big Switch® is filled and put in place, it should be anchored to the slope.

The preferred anchoring method is to drive stakes through the center of the tube at regular intervals; alternatively, stakes can be placed on the downstream side of The Big Switch®.

Stakes should be wooden and of appropriate length to provide 12” embedding in the ground + the sock diameter + 2” sticking above the sock and up to a 10’ spacing.

Stakes can be easily pulled up to move the The Big Switch® to other areas for erosion control and filtration.

The ends of the Filter should be directed up-slope to prevent storm water from running around the end of The Big Switch®.

The Big Switch® are often cut open when the project is completed, and the filter material is spread around the site as a soil amendment.

By the way, to make it easier for you and your crew, installation services are available, simply ask about it when you call.

If you decide to give The Big Switch® a try, then we promise you won't be disappointed.
