Coconut coir fiber is one of the thickest and most resistant natural fibers available for commercial use. Because it takes a long time to decompose and it is very strong, coir erosion control products are ideal for many restoration projects and for landscaping in areas where erosion is a problem.
Restoring Riverbanks and Wetland Areas
Riverbanks and wetlands are essential to wildlife and their habitats, but they can become unstable. Using coir blankets and mats to control erosion will help. The erosion control blankets contain the natural coconut fibers, and when placed along a riverbank or on a steep slope, they help to stabilize the soil. This, in turn, allows vegetation to take root and reduce further erosion. These coir blankets are the perfect solution for areas where the climate or shade increases the time it takes for seeds to germinate.
Coir logs are an effective tool for stabilizing the banks of rivers, streams that run along steep banks, or waterways with strong waves and currents. Coir logs are strong and flexible, making them ideal to place along the banks to help control erosion. The densely-packed logs contain the biodegradable mattress coir and create a natural control area. The logs are easy to place and easy to connect together, and they are strong enough to hold up against crashing waves. Since they last anywhere from two to five years, it gives seeds enough time to root and grow. The logs will slowly biodegrade, leaving behind a sturdy riverbank.
Support Vegetation Growth
Coir is a natural product that contains no weeds. This makes it an ideal product to protect landscaping from weed growth and support the growth of vegetation that will grow to defend against long-term erosion. The design of coir mats includes a structure that prevents weeds from growing through while allowing new plants to root and grow strong.
Coir to Filter Sediment
A combination of coir mats and coir wattles will filter sediment in streams and drainage ditches. This helps control erosion by reducing flows in the streams and control bed erosion around trenches. Construction companies often use this technique to protect the drains near their construction sites and to prevent runoff. A small coir wattle placed in front a drain will retain the sediment and sand while allowing the water to flow through. This keeps the water flowing and prevent flooding around the drains, which can lead to erosion.
Add Stable Height to Shorelines
Coir products are successful in adding height along riverbanks. Placing coir erosion blocks along the banks will build stability and strength. The blocks often come in sections that are 12 to 18 inches high, and they are easy to join together to support stretches of riverbanks. The rectangular shape of the blocks creates a layered design. The coir lasts for several years, allowing seeds to germinate and grow so the area will protect itself long after the coir decomposes.
Coir is a versatile, plentiful, and renewable material that can be creatively used for many different purposes. Erosion control is one of the valuable and ecologically sound uses for this remarkable product.
