Straw Blankets Erosion Control

I am interested in straw blankets erosion control products and I have some questions. What is the difference between a single net and double net blanket? How long will these blankets last? Is there any limitations on how, where, and when they can be used?

The Straw Erosion Control Blankets are an excellent choice for short-term erosion control on a bank, slope, stream or channel. Depending on your application, different erosion control blankets may work better than others at controlling your erosion.

Single or Double Net Blankets

In general, the main differences you will fine between a single or double net straw blanket is in terms of their construction. The single net blanket will feature a filler of straw, surrouded by only single polypropylene netting. The double net blanket will use the same filler material, but instead feature double polypropylene netting for added strength.


Single Net Blankets

Different single net blankets may work better than others, but the general lifespan for this blanket will be approximately twelve months (12 months). Places where you may find these blankets being used have included:

  • Low-Flow Channels
  • 3:1 Slopes or lower


Double Net Blankets

Some of the strongest double net blankets can be used over a time period of approximately twelve to twenty-four months (12 - 24 months). Areas where these blankets may be used have included:

  • Medium Flow Areas
  • Channels
  • Slopes Ranging from 3:1 to 2:1



PLEASE NOTE:
While this may provide a general overview regarding straw blankets erosion control products, the details for individual products can always vary. Some double net straw blankets are lighter in strength (approximately 90 days) while others can be higher.

In addition, many straw blankets erosion control materials will also include the use of a coir material. Coir is typically a much stronger material than straw and can help increase the lifespan of your blanket.
