Coir Geo-Textiles

Product Range Of Coir Geo-Textiles:

Coir geotextiles are emerging as an excellent media for soil bio engineering applications in the form of Meshes, Nettings, Needled felts, Geo Rolls, Blankets, Vegetation fascines, Geo beds and so on. They are being extensively employed to combat a variety of environmental challenges.  

  • Woven coir Geo-Textiles
  • Non Woven Felts
  • Coir Beds
  • Jute Geo-Textiles
  • Applications:

    Coir geotextiles are currently used in erosion control measures such as growing of vegetation on highway shoulders and embankments and also in protecting the banks of lakes, canals and rivers.   

    Coir geotextiles give maximum protection to the soil until the grass takes root and provides a permanent coverage. After the stabilization of soil, the nettings decompose gradually and provide nourishment to grass growing on the soil medium. The netting gives plenty of room to grow and at the same time provide a large number of “check daks”. 

    The accuracy of Coir geotextiles, with a density of 500g/m2, in reducing the water velocity and soil loss is reported to be 77% and 98.4% respectively relative to bare soil conditions (cammack-1988). Schurholz 1988 reports that coir retained about 20% of its strength after one year in incubator test with soil at 28-30ά c and 90% humidity whereas jute biodegraded fully after eight weeks. 

    Coir geotextiles can be used either as an overlay or an interlay – the former protecting the surface from run-off and the latter performing the functions of separation, filtration and drainage. Soil bio – engineering with Coir geotextiles finds effective application in the following situations:

    • Water course protection including stream bank protection
    • Shoreline stabilization
    • Storm water channels
    • Slope stabilization in railway cutting and embankments
    • Water course protection
    • Separation application in rural roads, railways, parking and storage areas
    • Reinforcement of rural unpaved roads, temporary walls Providing sub base layer in road pavement
    •  Filtration in road drains and land reclamation
    • Containment of soil and concrete as temporary seeding etc.
    • Concrete column curing
    • Fly ash dump waste protection and greening Forestry revegetation
    • Highway cut and fill slopes
    • Control of shallow mass waste and gully erosion
    • As sound barrier
    • UV protection for under earth crops
    • Roof top greening
    • Protection from wind erosion
    • Storm shuttering
    • Agricultural and horticultural applications like mulching, antiweed, vegetative water channels
    • High traffic areas
    • Mine site reclamation
    • High altitude ski slopes
    • Dune rehabilitation Wetland environments
    • Landscaping
    • Plant and tree protective systems
    • Agri and Horti engineering industry
    • Mud wall reinforcement
    •  Soil stabilization. 


    Coir nettings with tensile strength and the friction between coir and soil is adequate to justify its application for use in slope stability problems and helps development of shear surface and thus enables greater heights of fill to be built than would otherwise be possible. 

    Coir sub – base layer in Road pavements

    The use of closely knitted Coir geotextiles as an interface between the sub grade and the sub base increases the strength of the pavement and prevents intermingling of the soil and the granular sub base and improves drainage. Coir net also acts as a support membrane and reduces localized distress to the road surface by redistributing traffic loads over a wider area of the road surface. Figures show the suggested pavement with coir fabric. 


    Unique advantage of coir geotextiles when compared to other natural fibers is that frequency of watering can be reduced due to its high water retention capacity (can hold 3 times its own weight).

    Coir cut fibre: the small fibre bit which is waste during the sieving of coir dust is used as growing media in the horticulture and floral gardens.

    Coir basket and poles: the combination of soak and grow and the liner gives maximum moisture retention for your basket plants.

    Coir liners: all wall mounted baskets come with rubberised coir liner and universal wall mount. The wall mount is also ideal for attaching the basket to fencing without the need for drilling holes.

    Husk chips: dried husk are cut into various small, medium, large size mixed with charcoal and firewood and used as hot mixture for orchid and anthurieum plantations.

    Unique advantages of MAXIMA Coir Geotextiles

    • Faster binding of soil

    • Excellent air and water permeability

    • Enough sunlight passes through

    • Holds the seeds and saplings in place

    • High water retaining capacity

    • Excellent medium for quick vegetation

    • Degrades over a period of time (2.5 to 6 years)

    • Allows for deep rooting of plants and provides nutrients.

    • Easy to install and follows the contour of the soil surface.

    • Eco-friendly and nonpolluting.

     The unique properties of coconut fiber and Coir geotextiles to absorb water and degrade with time give it a definite edge over synthetic geotextiles in various applications. The use of geotextiles during the past three decades has increased from 10.2 million Square. Meter is 1970 to 1400 million square meter in 2000. But the Geotextiles made out of natural fiber account for only 0.001%. The rest is enjoyed by plastic materials!! The major drawback in coir Geotextile industry is non availability of proper specifications/procedure as well as that of well documented scientific field studies. 

    Application Techniques of MAXIMA Geotextiles

    Site assessment

    The first step in the application of Coir Geotextiles is to make a detailed study of the sites; Slope assessment, nature and consistency of the soil cover, the extent of damage, rainfall patterns etc. to make the right and relevant choice of Coir geotextiles for the site, as well as the seeds or saplings. Site preparation and laying procedure 

    The ground has to be prepared by removing protruding stones, earth masses etc. The surface must be made relatively free of weeds, stones, roots, sticks, rivulets, gullies, crusting and caking. 

    After preparing the soil surface, the seeds have to be applied on the surface by hand broadcasting or by hydraulic means and the blanket/mat must be laid over the seeds almost immediately. 

    The seeds/plants have to be obtained depending on the climatic conditions, preferably the local species as per client’s instructions. The seeds after germination should take up deep rooting system. The seeds should match the soil conditions to get optimum germination, root development, vegetation density and longevity. 

    The erosion control blankets are to be laid in the direction of the water flow starting from the top to the bottom. The top portion has to be anchored in a cut trench and stapled or spiked to fix properly. Similar procedure has to be followed at the bottom of the slope also for best results. The blankets may be anchored with 11 gauge wire staples, of size 8” x 2” x 8” (U shaped) One or two doses of sprinkling is recommended if the weather is hot and dry. For the first few days, the moisture levels must be properly monitored to facilitate easy germination of the seeds. 

    The blanket will protect the slopes against rain water. The vegetation will get established to protect the slopes permanently and achieve greening effect on the surface. 

    Seeding/Planting Methods: Quick germination, sod forming, grass species must be used whenever possible. While seeding/planting always match the seed/sapling to be used with the local soil conditions for optimum results. Standard seed broadcast methods are acceptable prior to erosion control blanket installation.
