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
