Main Function of Geotextiles

•Separation•Filteration•Drainage

•Reinforcement•Protection

19

Function of Geotextiles Separation

• Prevent the soft subgrade from mixing

with the aggregate

• Construction at very soft subgrade

20

Function of Geotextiles Filteration

• Prevent the sand/soil of landfill from flowing out of

subsoil

• Land reclamation for sea coast

• filteration of drainage at underground

• filteration under concrete block at river bank

21

Function of GeotextilesDrainage

• Water drained from dampy soil by horizontal

drainage effect

• Drainage work at sports field/campus

22

Function of Geotextiles Reinforcement

• Protected from shear destruction of subgrade

• increasing the stability of embankment

• Reinforcement of embankment at road base, farmland and home foundation

23

Function of Geotextiles Protection

• Prevent the breakage of rubber sheet

• water drained through the fabric

• Protection of water-proofing geomembrance at water dam and tunnel workd
