Biodegradable Erosion Control Through Straw Blankets and Wattles

Because of their biodegradable straw fiber material, straw wattles and straw blankets provide similar benefits. Both are environmentally safe and completely biodegrade, limiting the need for extra labor to remove them, and will blend into the environment once they break down. Both are also made of natural, inexpensive materials popular for erosion control and are lightweight

Straw Wattle Features

Standard diameters of 9 inches, 12 inches, or 20 inches
Interior is biodegradable wheat straw
Exterior is synthetic photodegradable netting

Straw Wattles and Blanket Benefits

Will naturally biodegrade
Ideal for short term projects
Environmentally safe

Both are ideal solutions for short term erosion control on slopes, river banks, and anywhere with a low flow.

Straw Wattles

Straw wattles are constructed from 100 percent wheat straw and are used for filtration for storm drains, construction site perimeters, and other erosion-sensitive areas. Straw wattles retain sediment and prevent pollution. Because of their round structure, they are commonly used in places with low flows, usually around slopes and streams, and their rounded ends can be connected to meet project needs.

Straw Wattle Installation

When installing straw wattles, ensure that the ground is free of debris and place wattles in the desired location. Secure wattles in place with staples or stakes when used in sediment. If using wattles before storm drains on concrete or asphalt, straw wattles can be secured with sandbags, gravel bags, or other weighted materials. See our guide for more information on Straw Wattles Installation (PDF).

Straw Blankets

Straw blankets are made from either a single or double net of biodegradable jute, photodegradable polypropylene or rapid degrade material that creates a barrier around wheat straw fabric. Straw blankets are a short-term erosion control product that establishes vegetation and prevents erosion on slopes or places with low water flow.

Straw Blanket Installation

Installing straw blankets will depend on the steepness of the slope. First, prepare the installation areas by removing debris, leveling the soil, and adding vegetation or seeding. After preparing the area, lay the blankets in place.

The tops of each blanket should be installed into a 6 in. trench, which is then filled for added stability. Depending on the slope of the area, staples should be placed periodically throughout it.

For specific, step-by-step instructions, see: Straw Blanket Installation Guide (PDF)
