Coir geotextiles – Soil erosion can be avoided by using the land according to its capacity. The position of the land, the type of soil, and the slope determine its vulnerability to erosion. May not be suitable for agriculture or solely for erosion control activities.
There are a number of resources to help determine how soil should be used to prevent erosion:
* For Farmland: Land Management Field Guides show and describe land types in many regions and provide land use and management recommendations for each soil type. Browse our library catalog and find land management field guides.
* For Grasses: soil and land type maps are available for most regions. They give ranchers an idea of the nature of the soils on their property and are a useful planning tool.
Using Coir Geotextiles for Surface cover and Runoff
The surface cover is an important factor in erosion control because it reduces the impact of raindrops falling on bare soil and wind-carrying soil particles. It also slows down the speed of water flowing over the land. The risk of erosion is considerably reduced when the soil cover is greater than 30%. Full coverage can be achieved for many grazing and cropping systems.
Runoff is concentrated when it flows downward. When rivers that drain large basins reach the coast, they are usually several hundred meters wide. Although surface cover helps disperse runoff, runoff concentration is unavoidable. Basin-scale coordination is important to implement flow control measures. Runoff can cross multiple properties and cross multiple roads (sometimes railroads) as it travels from the outermost part of the watershed to the main drain line or creek.
Erosion Protection Covers with Coir Geotextiles
Coir geotextiles is a natural geosynthetic erosion control product that is a flexible, lightweight 3D mat made from a high strength coir geotextile that is used to protect surfaces of slopes or protect against soil erosion, reducing emissions and promoting infiltration. The erosion protection mat serves both to protect the soil surface from washing away and to quickly create a lawn.
In other words, coir geotextiles stabilized coir geotextile reduces the possibility of erosion caused by torrential rains and provides a green layer of vegetation on streams, river banks, pond banks, slopes steep and grassy marshes. The vegetated coir geotextiles not only prevent soil and sediment erosion but also provide excellent filtration and vegetation, improving soil condition and slope stability.
Categories of coir geotextiles
Coir geotextiles are made from coir fiber which has undergone various processes. As a natural product, coco geotextile is a biodegradable and environmentally friendly product. They are divided into 2 categories according to their method of preparation:
- Woven Coconut Geotextiles
- Nonwoven Coconut Geotextiles
1. Coconut woven geotextiles
This form is the simplest. The coir geotextile is traditionally made manually using the 2-axis weaving technique. This form is primarily used for erosion control applications. The variations of this one are made according to the intensity of the rains, the type of soil, and the slope of the surface. Each variety can be identified by its weight per m2 and its type of yarn.
2. Non-woven coconut geotextiles
The type of coir geotextile is often referred to as coir filter cloth. Made from the same materials as nonwoven coconut shell geotextiles in sheets and nonwovens. The coconut fibers are pressed and heated with special glue.
Coir Geotextiles Manufacturing Process
Materials and tools:
- Slightly aged coconut fiber
- Coir decomposer
- Coir spinning machine
Manufacturing process :
- Prepare fairly old coir
- Grind coconut shell into coir with coir crushing machine
- Sponge the ground coconut fiber dry.
- Spin the coir in a mine with the coir spinning machine
- Weave the rope into a net (cocomesh)
- Ready-to-use coir/cocomesh netting
