Geo grids, geo textiles, geomembranes, geo cells are some of the Geosynthetics.
They are made from petrochemical based polymers (plastics) that are biologically inert and do not decompose from bacterial or fungal action.
Applications:
a) It is used to improve soil properties
b) It is used for drainage
c) Also used for soil stabilization
d) Used for erosion control
e) Used for road construction
f) Used to improve level grade soil situations like roads, valleys, laneways.
g) To improve slope grade situations such as banks, hill sides.
