CoirGreen™ Geotextiles - An Effective Soil Erosion Prevention Method

“The different coir types and their characteristics have made coir the most versatile natural fiber to combat erosion and to restore waters and wetlands. Thus, coir seems to be the miracle fiber of this century to save the earth, its waters and wetlands” – Land and Water Magazine

The use of natural fibers for erosion and sedimentation control dates back to the beginning of this century. The main problems in the early natural fiber textiles (example jute mats) were low tensile strength, high elongation and low durability. These drawbacks restricted their use to only less severe erosion problems. An alternate natural fiber that has drawn the attention of the erosion and sedimentation control industry is coir, the coconut fiber.

One of the most effective and yet natural soil erosion prevention techniques is the use of coir geotextiles (coir netting) fabrics. CoirGreen geotextiles have no synthetic material but are instead made out of organic fiber coir, which is extracted from the husk of a coconut. Coir is strong, durable, waterproof and one of the few natural fibers that is salt water resistant.

The lighter varieties of coir woven geotextiles are used for immediate soil erosion and ordinary soil conditions while the heavier coir geotextiles are used for embankments, slopes or vegetation. CoirGreen geotextiles protect the soil until the vegetation permanently covers its mesh.  It gives the plants adequate room to grow and decomposes naturally into humus which will enrich and nourish the soil. Lasting between two to five years the coir fiber, compared to other natural fibers such as jute, has several unique features. CoirGreen geotextiles have the ability to retain water three times more than its actual weight preventing the need to frequently water the plants. However, at the same time with its adequate space within the mesh it drains the excess water easily preventing water logging. With an easy installation method the CoirGreen geotextiles need no chemical treatment as it lets in the right amount of air and light for a deeper rooted plant. It can also endure animal and human movements that would generally lead to more environmental decay.

The Food and Agriculture Organization (FAO) states,

“Recognition of coir for sustainable vegetation and erosion control arises from the fact that it is an abundant, renewable natural resource with an extremely low decomposition rate and high strength compared to other natural fibers. Coir is woven into thick textiles which are applied like blankets on the ground in erosion prone areas. Geotextiles made from coir are durable, absorb water, resist sunlight, facilitate seed germination, and are 100% biodegradable. These blankets have high strength retention and a slow rate of degradation meaning they last for several years in field applications”.

Studies conducted have proven that coir geotextiles are effective, inexpensive and environmentally friendly. In one study conducted in 1998 on coir geo textiles, Schuerholz found out that coir retained 20% of its strength a year later  and 90% humidity whereas jute biodegraded fully after eight weeks.  In another study, conducted in Kerala, India, with a farmer community in 2005, scientists found out that coir combined with local grass  prevents soil erosion.

CoirGreen geotextiles have varying densities depending on their application, but as a whole they serve as slope stabilization agents prior to re-vegetation. CoirGreen geotextiles promote new vegetation by absorbing water and preventing topsoil from drying out. They absorb solar radiation just like natural soil, and unlike geosynthetic materials, they provide good soil support for up to three years, allowing natural vegetation to become established. The greater the geotextile density, the steeper the embankments it can be utilized on. Applications have included ski slopes and bottom reinforcing material in water courses.

 

The uses of CoirGreen geotextiles can be summarized as below,

●     Stream/River bank protection

●     Shoreline stabilization

●     Slope stabilization in railway cutting and embankments

●     Separation application in rural roads, railways, parking and storage areas  and storm shuttering

●     Reinforcement of rural unpaved roads, temporary walls providing sub base layers in road pavements

●     Filtration in road drains and land reclamation

●     Containment of soil and concrete as temporary seeding

●     Concrete column curing

Eco-friendly and effective soil conservation products by CoirGreen

In line with its vision to be an ambassador for the environment, Coir Green recently launched four upgraded environmentally friendly products that focus on soil conservation. The products are alternatives to hard revetments such as concrete and stone walls. Using soil conservation products made out of coir is very advantageous. Coir fibre comes from an entirely renewable source and is a by-product from an established industry where it was formerly regarded as a waste product. Furthermore, coir uses water economically and is also an ideal soil improver. Therefore, using products made out of coir is environmentally beneficial.

The upgraded soil conservation products are

·         Erosion control blankets

·         Geotextiles

·         Coir Logs and

·         Coir Pallets

Erosion Control Blankets

Coir erosion control blankets, also known as coconut blankets or coir blankets, are used extensively for slope stabilization, landslide stabilization and river-bank protection purposes.  They are easily transported and deployed, can be secured in place, and can eventually become part of the soil structure.  The blankets are environmentally friendly and do not pose potential contamination risks.  There are no hazardous chemicals or synthetic materials within the matrix.  Over a period of time coir, which is eco friendly and biodegradable, completely disintegrates leaving only humus.

Geotextiles

Geotextiles or Coir netting (Coir matting) CGgeo ™ reduces soil erosion and is used globally for bioengineering and slope stabilization applications. Geotextiles have no synthetic materials. They are strong, durable, waterproof and salt water resistant. Geotextiles are used for stream/river bank protection, shoreline stabilization, slope stabilization in railway cutting and embankments, sediment control and so on.

Coir Logs

The easy to install, 100% natural Coir Green logs are made out of cylinder or square shaped netting packed with coir fiber. The logs are eco-friendly and biodegradable. CG logs are used for stream bank stabilization, shoreline protection, wetland mitigation etc. The logs can easily be anchored with wooden stakes.  Over a period of time the logs completely disintegrate leaving only humus.

Coir Pallets

Coir pallets, also known as coir pillows, are widely used for establishing vegetation around lakes, canals and rivers. The pallets are a suitable alternative to hard revetments. Coir has a high content of lignin and this means that the fibre can cope with high-energy water flows and has a long degradation period of 3-5 years.  Coir Green produces coir pallets which are 100% natural and biodegradable. The pallets are made from a combination of mattress fibre and coir netting cases.

The Earth’s soil provides ecosystem services which are critical for life. The soil acts as a water filter and a growing medium.  It provides habitat for billions of organisms; contributes to biodiversity and supplies most of the antibiotics used to fight diseases. Humans use soil as a holding facility for solid waste, filter for wastewater, and foundation for our cities and towns. Soil is the basis of our agro ecosystems which provide us with feed, fiber, food and fuel.

The Environment is Our Lifeblood at CoirGreen

“When we heal the Earth, we heal ourselves”. These wise words were uttered by a distinguished professor of Environmental Studies in the United States, David. W. Orr.

We live in a time when the insufferable arrogance of man has laid waste to the most beautiful planet in the solar system. The current statistics regarding the Earth’s environment portray a scary picture. The world’s rain forests could completely vanish in a hundred years at the current rate of deforestation. Since 1500, more than 800 species of plants and animals have gone extinct. Climate-related deaths will double in 25 years according to a 2005 report from the World Health Organization. Climate change is already tied to 150,000 deaths globally every single year. Scientists predict a 6 foot rise in the global sea level and global warming has become a reality with 8 of the warmest years ever recorded occurring after 1998.

These stats underscore the importance of taking every effort to preserve our planet. At Coir Green^(tm) we have always been driven to create products that are environmentally sustainable. And since our inception we wanted to be a responsible company and be an example to the wider society.

At the heart of all CoirGreen^(TM), products is coir, the coconut fibre found between the husk and the outer shell of the coconut. The use of coir has several environmental benefits. Coir fibre comes from an entirely renewable source and is a by-product from an established industry where it was formerly regarded as a waste product. It uses water more economically and is an ideal soil improver.

The Live Strong foundation says

“The importance of coir can be stated quite simply. You can escape from a burning building with a rope made of coconut fiber, you can garden using coconut fibers and you can sleep on a mattress stuffed with comfortable coir.”

Adding to the above quote, we can also say that products made from coir safeguard the soil, nourishes our gardens and protects the environment.

Coir is also a viable alternative to peat moss. Peat moss bogs are a non-renewable resource and they provide habitat for a distinctive flora and fauna. Removing the peat moss destroys this environment and it takes centuries to recover. A recent article in the Guardian endorsed coir as a good alternative to peat moss and recommended its usage in British gardens. In fact, the historical Kew Gardens in London used coir as a growing medium during the early 19th century. And when researchers at Auburn University and University of Arkansas compared peat and coir as soil amendments for horticulture they found that coir performed on par with peat.

At CoirGreen^(TM), we produce a variety of coir related products. Our coir products are made for the horticultural, agricultural and the erosion control industries. Erosion control blankets, Coirlogs (Waterlogs/Biologs), Geotextiles (Coir netting), coir pallets (Coir Pillows), coco peat, coir disks(weed control mats), coir pots and Growbags are some of our products. All CoirGreen products are environmentally friendly and completely biodegradable. Our products are also 100% natural and chemical free.

CoirGreen’s ultimate goal is to be an ambassador for the environment by promoting the use of environmentally sustainable products. We spend an enormous amount of energy in making sure that our products do not harm the environment in anyway. CoirGreen^(TM) is nurtured by the environment and the coconut tree that gives life to our company. The environment is our lifeblood and we believe that it is our duty to take care of it.

Using Coir Erosion Control Blankets for Erosion Control

Coir is a natural fiber extracted from the husk of the coconut and used in products such as weed control mats, Growbags, Coir pots, mattresses, erosion control products, landscaping mats, etc. Technically “Coir” is the fibrous material found between the hard, internal shell and the outer coat of a coconut.  Coir is an excellent natural material for use in soil erosion control products and is used extensively in landscaping projects. 

Coir blankets are well known for superior performance since Coir is naturally resistant to rot, mold and moisture. It needs no chemical treatment. Hard and strong, it can be spun and woven into matting (Geotextiles) as well. Blankets provides adequate strength and durability to protect slopes from erosion, while at the same time allowing vegetation to flourish.

Coir erosion control blankets, also known as coconut blankets or coir blankets are used extensively for slope stabilization, landslide stabilization and river-bank protection purposes.  They are easily transported and deployed, can be secured in place, and can eventually become part of the soil structure.  They are environmentally friendly and do not pose potential contamination risks.  There are no hazardous chemicals or synthetic materials within the matrix.  Over a period of time, coir, which is eco-friendly and 100% bio-degradable, completely disintegrates leaving only humus. 

Coir blankets are also excellent for use in landscaping, vegetation control and sediment control purposes. Coir fibers have an advantage over synthetic fibers. They are highly water absorbent, while retaining their physical properties. They store up water and build an ideal micro-climate for the seeds underneath. Of all natural fibers, coir has the greatest tensile strength.

Depending on your specific needs, several types of coir erosion control blankets are supplied by CoirGreen™.  These blankets are specifically designed to control soil erosion based on slope, water flow and duration.  The specific needs of the soil erosion control situation will determine which type of coir erosion control blankets should be used.

Erosion control blankets provide a natural alternative with flexible options for every landscaping situation from temporary to permanent application.  Coir blankets can be utilized in controlling even the steepest of slopes from erosion.  Seeding or planting with coir blankets is a simple process due to the blankets natural ability to retain moisture and protect from the suns radiation.

Coir soil erosion control blankets come in various lengths, widths and densities depending on your soil control needs.  In most cases, custom orders can be accommodated. More details on Coir Erosion Control Blankets, please visit www.coirgreen.com
