iGGtecx - Woven Coir Geotextile
Erosion control fabrics from the product group iGGtecx KGW, woven coir geotextiles, oftentimes are a more suitable alternative to iGGmat erosion control blankets, especially for construction projects on exposed areas at risk from erosion, as well as on shorelines of still waters and streams. A huge advantage is the long lifetime of three to five years due to the high lignin content of the coir fibers. Furthermore it is used if the desired vegetation needs more than one vegetation period to be established. The individual woven fibers slow the water speed of rainfall or of water streams and thus protect the soil surface and young plants. The denser the mesh, and thus denser the woven coir that is used on the soil surface, the greater is the protective effect. We recommend wooden pins or U-shaped fixing pins from the iGGfix product group for fastening iGGtecx KGW.
Woven coir is used as surface erosion protection for slope and embankment reinforcement in exposed terrain, water engineering and for shoreline stabilization. The selection depends on the slope of the area and the required duration of protection.
iGGtecx is applied on a prepared surface. The woven coir geotextile must lie completely on the soil with no spaces. The individual strips must be placed perpendicular to the slope of the embankment, next to each other over the entire area. Overlapping on the vertical longitudinal joints should be approx. 10 cm and on the transverse joints approx. 10-20 cm. The open edge of the overlap must be away from the predominant wind direction. Transverse joints must basically overlap from top to bottom. The top and bottom ends of the erosion control mat must be dug into the top and bottom of the slope approx. 10–20 cm deep and fastened. Fastening is done using iGGfix U-shaped wire pins or iGGfix wooden pins.
iGGtecx woven coir geotextiles KGW® is 100 % pure two-ply coir fiber and is not treated with chemicals. This means it is 100% biologically degradable.
Three types of weight are available: KGW®400, KGW® 700 and KGW® 900. The numbers represent the weight per unit area in g/m², which is the result of the thread spacing in warp and weft. The denser the yarn, the heavier the woven fabric.
In contrast to iGGmat erosion control blankets, iGGtecx woven coir geotextiles KGW® have an especially long durability and higher tensile strength.
