1 GWRL- An ISO 9001 2000 Company© 2011 GARWARE-WALL ROPES LTD. ALL RIGHTS RESERVED Innovative Technologies Building Trust APPLICATIONS OF GEO-SYNTHETICS IN EROSION CONTROL GARWARE – WALL ROPES LTD. Geo-synthetics Division

2 GWRL- An ISO 9001 2000 Company© 2011 GARWARE-WALL ROPES LTD. ALL RIGHTS RESERVED SOIL EROSION  Soil erosion is a natural process which occurs due to detachment and movement of top soil by the action of wind and flowing water  Natural turfing does not provide required superior performance  Erosion control measures:  Garmat ® on Slopes upto 45 º  Geocell on Slopes upto 80 º

3 GWRL- An ISO 9001 2000 Company© 2011 GARWARE-WALL ROPES LTD. ALL RIGHTS RESERVED High performance product specially engineered as surface protection treatment for slopes Garmat ® is a composite geomat comprising a layer of bio- degradable mulching material sandwiched between two layers of polymer netting GARMAT ® Garmat ® Pre-cultivation on Garmat ®

4 GWRL- An ISO 9001 2000 Company© 2011 GARWARE-WALL ROPES LTD. ALL RIGHTS RESERVED SPECIFICATIONS OF GARMAT ® PROPERTY SPECIFICATION OF GARMAT ® Top and bottom layers of polymer net Material and structure Polymer netting comprising tensile elements of circular cross-section in two orthogonal direction with knotless joint Aperture size 25 (  4) mm x 25 (  4) mm Tensile strength≥ 2.0 kN/m (in both directions) UV Stability (Percent retention of tensile strength) ≥ 80% (500 hours exposure) Type of jointFirm Joint Middle layer of bio-degradable mulch MaterialCoir fibre Weight≥ 250 gms/m 2 Thickness≥ 6.5 mm Dimensions Length15 m (depending on site requirement) Width5 m (minimum)

5 GWRL- An ISO 9001 2000 Company© 2011 GARWARE-WALL ROPES LTD. ALL RIGHTS RESERVED ADVANTAGES OF GARMAT ® Promotes growth of vegetation by retaining moisture and conditioning the soil Root system interwined with the net binds and confines the soil Results in higher root density of grass cover upto (4500 kg/ha) compared to ordinary turfing (typically 1500 kg/ha) Mulch in the Garmat ® acts as porous filter to allow water while retaining soil Installation is simple and easier
