Woven Coir Fibre Geotextiles
This woven geotextiles are made to matrix by running the yarns in warp and weft direction forming open mesh matrix. The open area will vary according to the number of  warp and weft yarn running in a specified area. The woven erosion control mats can be made out of either coconut coir yarn or high tensile bristle machine spun coir twine. The characteristics of these two grades of  geotextiles are as follows:

  • Coir Yarn Geotextiles - high wet tensile strength and functional longevity of 2-4 years combined with heavier weight is suitable for use in steep slopes and in channels with high flow velocities and high shear stresses.
  • Coir Twine Geotextiles -due to its high tensile strength and functional longevity of 5-7 years, these mats can be used in very steep slopes and in channels and ditches with shear stresses up to 5  lbs./sq. ft(240n/m2). This type of blanket, which is referred to as turf reinforcement mat (trm), is an ideal substitute for 100% synthetic blankets.

The standard weighs of the coir yarn and coir twine woven geotextiles are 400grms, 700 grams and 900 grams per sqm.

Stitched Beds

Stitched Erosion Control Blankets
The stitched erosion control blanket composed of processed, but not spun, fibres that have been made into a needled felt mat which is further structurally enhanced by a stitch binding manufacturing operation. These mats can be made to two basic types:

  • Open mesh netting grid placed on one surface of the mat
  • Open mesh netting grid placed on both surfaces of the mat

These blankets are made out of natural vegetable fibres such as coconut coir or straw (paddy) etc., with photodegradable or biodegradable top and bottom layers sewn together with degradable thread (i.e.: jute).

Also available filled with soil substrates or mulched with pre-seeded or and pre-cultivated blankets.

ProductGabion

Coco Gabion
Coir fibre stuffed and encased in a biodegradable netting, formed in a square shape structure. Coco gabion can be made with or without a steel frame.

This is an ideal product to be used in at a base of a slope where a low toe wall is needed to stabilize the slope and reduce slope steepness in a stream bank. Appropriate for use with soil bioengineering systems and vegetative plantings to stabilize the upper bank and secure a regenerative source of stream bank vegetation.

The main advantage of coco gabion is that it can be planted with live cuttings on any of its surface area.

Fibre substrate filled inside the coco gabion is an ideal medium for root development for the cuttings and, subsequently, these plants will consolidate the structure and bind it to the slope.

Gabion size can vary according to the buyer's specification.
Also available: coco gabion filled with coir fibre/chopped coir fibres and encased in a rectangular basket shape with galvanized wired steel mesh.
