Coir Geo Textiles
Coir
The thickest and most resistant of all commercial natural fibres, coir is a coarse, short fibre extracted from the outer shell of coconuts. Its low decomposition rate means is a key advantage for making durable geo-textiles.

Coir is extracted from the tissues surrounding the seed of the coconut palm (Cocos nucifera), which is grown on 10 million ha of land throughout the tropics.

The fibre
Coir fibres measure up to 35 cm in length with a diameter of 12-25 microns. A coconut harvest occurs once in 45 days. From 1000 coconuts it would be possible to extract 10 kgs of coir. Among vegetable fibres, coir has one of the highest concentrations of lignin, making it stronger but less flexible than cotton and unsuitable for dyeing. The tensile strength of coir is low compared to abaca, but it has good resistance to microbial action and salt water damage and needs no chemical treatment.

There are two types of coir: the more commonly used brown fibre, which is obtained from mature coconuts, and finer white fibre, which is extracted from immature green coconuts after soaking for up to 10 months. Mature coir fibres contain more lignin, a complex woody chemical, and less cellulose than fibres such as flax or cotton.

Environmental benefits
Coir is a material which is widely used to overcome the problem of erosion. When woven into geotextiles and placed on areas in need of erosion control it promotes new vegetation by absorbing water and preventing top soil from drying out. Coir geotextiles have a natural ability to retain moisture and protect from the suns radiation just like natural soil, and unlike geo-synthetic materials, it provides good soil support for up to three years, allowing natural vegetation to become established.

Geotextiles
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 a 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.

The coir geotextiles in the road construction
Coir geotextiles due to inherent properties like highest strength among all the natural fibres and high water absorption with maximum swelling of only 5% and very high extensibility of 30% have been found to be the ideal replacement of the geosynthetics normally used in the construction of roads to stabilize the sub grade agrarian soils.

Coir Netting is placed between the weak sub grade soil and the aggregate fill:
The Coir Geotextiles :
  • Provide a physical barrier to the intermixing of the aggregate and sub grade soil
  • Provide local reinforcement
  • Restrain the aggregate sub-base from downward and lateral movement in the rut
  • Restrain the sub grade soil from upward and lateral movement between the ruts
  • Act as a support membrane
  • Provide sufficient friction to limit lateral sliding of the aggregate

  • Coir Geotextiles as reinforcement material
    The Coir geotextiels find use to reinforce the soils that are poor in tension thereby reducing applied stress on the sub grade and preventing rutting caused by sub grade overstress.

    The Coir getextiles are having high tensile strength at low stains, ie high modulus, therefore are considered to be the best materials amongst other natural fibres used for this purpose especially in unpaved roads.

    Coir Geotextiles for filtration and driange.
    The Coir geotextiles provide an edge over the natural fibre geotextiles in providing good separation as well as adequate filtration by retaining soil particles and allowing water to flow across the plane due to the inherent porosity (40%) of the fibers.

    The above findings are based on the studies carried out at the laboratory level and field level by the CCRI in collaboration with the institutes having expertise in the Construction of roads in India, The Indian Roads Congress (IRC) has given accreditation to the use of coir geotextiles for the use in the construction of roads. It has mentioned that the coir geotextiles having mass per unit area of 400 t0 900 g/m2 could be used.

    These erosion control mattings are designed using coir fiber materials to create a strong mat for stabilization and erosion control along banks, slopes, hillsides, and streams. Designed to be strong and durable in their construction, these erosion mats are made from 100% machine-spun coir twines for effective erosion control in all locations. Mats are semi-permanent and offer a lifespan of approximately 4-6 years.

    This particular erosion control mat has an open weave design with .75” x .75” openings. These openings allow you to reseed before and after installation, as well as allow for planting plugs to be installed. 100% natural and biodegradable, there are no synthetic materials present in this blanket.
