Geotextile fabric is a synthetic permeable textile material commonly used in civil engineering, construction, and landscaping applications to improve soil stability, provide erosion control, and aid in drainage.
Key Characteristics:
-
Material: Made from synthetic fibers like polypropylene or polyester.
-
Permeability: Allows water to pass through while blocking soil and other particles.
-
Durability: Resistant to biological and chemical degradation, UV exposure, and mechanical wear.
Types of Geotextiles:
-
Woven Geotextiles
-
Non-Woven Geotextiles
-
Manufactured by bonding fibers together through heat, needle punching, or chemical processes.
-
Excellent for filtration, drainage, and separation.
-
Commonly used in landscaping, erosion control, and French drains.
-
Knitted Geotextiles
Common Applications:
-
Road and railway construction (separation and stabilization)
-
Retaining walls (reinforcement)
-
Drainage systems (filtration)
-
Erosion control on slopes and riverbanks
-
Landfill liners and caps
Benefits:
-
Prevents soil erosion
-
