Coir Geo Textile
- Coir Geo textiles will be used for construction of rural roads under the Pradhan Mantri Gram Sadak Yojana (PMGSY-III).
- The project will be implemented by the National Rural Infrastructure Development Agency (NRIDA) under Union Ministry of Rural Development, Govt. of India.
- In March, 2020, the government had announced National Technical Textile Mission and the use of geo-textiles in highways, railways and ports were envisaged in the proposed mission.
- As per the PMGSY new technology guidelines for road construction, 15% length in each batch of proposals is to be constructed using new technologies.
- Out of this 5% roads are to be constructed using Indian Road Congress (IRC) accredited technology. The IRC has now accredited coir Geo textiles for construction of rural roads.
- As per these instructions, 5% length of the rural roads under PMGSY-III will be constructed using Coir Geo textiles.
- 1674 km road will be constructed using Coir Geo textiles in 07 states for which there will be a requirement of One Crore Sq. mtrs of coir Geo-textiles, estimated cost of which would come to Rs.70 Crore.
- The decision will give a big boost to the coir industry especially in these difficult times of COVID-19 pandemic.
- Geo textiles are permeable fabrics which, when used in association with soil, have the ability to separate, filter, reinforce, protect, or drain.
- Typically made from polypropylene or polyester, geotextile fabrics come in three basic forms: woven (resembling mail bag sacking), needle punched (resembling felt), or heat bonded (resembling ironed felt).
- Geotextiles and related products have many applications and currently support many civil engineering applications including roads, airfields, railroads, embankments, retaining structures, reservoirs, canals, dams, bank protection, coastal engineering and construction site silt fences or geotube.
- Usually geotextiles are placed at the tension surface to strengthen the soil.
- These are also used for sand dune armoring to protect upland coastal property from storm surge, wave action and flooding.
Coir Geo Textiles
- It a permeable fabric, natural, strong, highly durable, resistant to rots, moulds and moisture, free from any microbial attack, has finally been accepted as a good material for rural road construction.
- Totally biodegradable, geo textiles help soil stabilisation and renew vegetation in varying slopes.
- 100% Natural fibre, extracted from coconut husk
- Adds organic material to soil
- Promotes vegetative growth
- Environmentally friendly
- Tough, durable, versatile and resilient
- High tear-strength resistance
- Easy to install/maintain/ patch-up.
- Follows the contour of the soil surface.
- Hygroscopic properties (absorbing or attracting moisture from the air)
- High tensile strength
