Straw wattles are intended to help prevent soil erosion, chemical and water runoff, and increase healthy infiltration within the ground. They are installed on slopes that have less than 30% of its original ground cover and are considered at risk for increased erosion.
What do straw wattles do?
Straw Wattles increase infiltration, add roughness, reduce erosion, and help retain eroded soil on the slope. Straw Wattles should be effective for a period of one to two years, providing short term protection on slopes where permanent vegetation will be established to provide long term erosion control.
Can you drive over straw wattles?
When straw wattles are used for flat ground applications, drive the stakes straight down; when installing wattles on slopes, drive the stakes perpendicular to the slope. If you have difficulty driving the stake into extremely hard or rocky slopes, a pilot bar may be needed to begin the stake hole.
How do you use wattle for erosion control?
BEGIN AT THE LOCATION WHERE THE WATTLE IS TO BE INSTALLED BY EXCAVATING A 2-3” (5-7.5 CM) DEEP X 9” (22.9 CM) WIDE TRENCH ALONG THE CONTOUR OF THE SLOPE. EXCAVATED SOIL SHOULD BE PLACED UP-SLOPE FROM THE ANCHOR TRENCH. 2. PLACE THE WATTLE IN THE TRENCH SO THAT IT CONTOURS TO THE SOIL SURFACE.
What is a straw waffle?
Straw Wattles in VARIOUS SIZES Straw Wattles are man made tubes of compressed straw, wheat or rice, also known as erosion logs. They provide perimeter protection along contours or at the base of slopes, inlets and roadways to reduce soil erosion, runoff and retain sediment.
What is a wattle trench?
Installation of wattles begins by constructing a shallow trench, 2 to 4 inches deep, and shaped to accept the wattle, along the contour of the slope. The wattle is placed in the trench, and excavated material from the trench is packed tightly along the base of the wattle, on the uphill side.
How do you prevent erosion on a slope?
To guard against these slow but sure soil eroders, you can use a combination of these five techniques. 1) Build A Garden Terrace. Preventing soil erosion on a hillside is a steep challenge. 3) Use Sandbags As Diversions. 5) Use Geotextiles Or Erosion Control Blankets.
What is the purpose of a fiber roll?
A fiber roll is a temporary erosion control and sediment control device used on construction sites to protect water quality in nearby streams, rivers, lakes and seas from sediment erosion. It is made of straw, coconut fiber or similar material formed into a tubular roll.
What is jute netting?
Made from the woven fibers of the jute plant, jute netting, or mesh, is a biodegradable, natural, and flexible material used for temporary erosion control and selective plant establishment. Jute mesh has openings in the weaves, which trap seeds and provide a protective environment for germination.
Is Rip a rap?
Riprap is a permanent layer of large, angular stone, cobbles, or boulders typically used to armor, stabilize, and protect the soil surface against erosion and scour in areas of concentrated flow or wave energy.
How do they make straw blankets?
The straw is sewn together with netting on both sides to form the blanket. The blankets are rolled out at road construction sites to keep dirt from washing away while still allowing new grass to grow under the blanket. Another product they make are called wattles.
What is a waddle in landscaping?
erosion control landscaping watershed restoration Mar 20, 2017. Straw wattles (aka fiber rolls) are fiber filled mesh tubes used to interrupt and slow water descending a slope through sheet flow and/or minor rill/gully formations.
What is a fiber log?
Fiber rolls (also called fiber logs or straw wattles) are tube-shaped erosion-control devices filled with straw, flax, rice, coconut fiber material, or composted material. Each roll is wrapped with UV-degradable polypropylene netting for longevity or with 100 percent biodegradable materials like burlap, jute, or coir.
Do rocks help with erosion?
Rocks are typically used to prevent erosion by water, not wind. Rounded stones are not as effective as rocks that are jagged or angular in shape that tend to “knit” or lock together. Rocks should be less than one-third as wide as they are long.
How do you keep soil from washing away on a slope?
Mulch. Mulch is a good choice if your slope is less than 33 percent, and the right mulch can help to keep soil in place on a gentle slope with or without plants. Use at least 3 inches of mulch that resists washing or blowing away during a rainfall or high winds.
Do wattles work?
They do a good job in catching water as it goes down the slope. Wattles can be made out of straw, and as time passes, it blends in with the soil and adds moisture. Wattles also work very similarly as erosion control blankets since they maintain ideal conditions for the soil below.
How long is a wattle?
They are usually 37.5–45 centimetres (14.8–17.7 in) long. Body mass in males averages 168 g (5.9 oz) and in females averages 123 g (4.3 oz), with the largest males weighing up to 260 g (9.2 oz). They are named for the wattles hanging from the cheeks. Yellow wattlebirds are slim birds with a short, strong bill.
When should we use jute mesh?
When to Use Jute netting can be used on areas that may erode near structures such as homes, roads, and bridges or on small, steep, disturbed areas. Netting can also be applied alone (without mulch) as an alternative to straw or wood mulches on flat sites for dust control and seed germination enhancement.
How much does jute netting cost?

How long does jute netting last?
Jute erosion control netting is best used on sites with low-to-moderate slopes (up to 3:1). Water flow through the project area should also be low-to-moderate (no more than 6 feet per second). Under these conditions and if properly anchored, it should last in the field for 6-to-9 months.
