Geotex fabric is a permeable synthetic textile material used in geotechnical engineering and construction projects. It is typically made from polypropylene or polyester and comes in woven, non-woven, or knitted forms. Geotex fabric are designed to improve soil stability, provide erosion control, and aid in drainage, among other functions.

1.1 Geotex Fabric – Woven Geotextiles

  • Made by weaving fibers together.
  • High tensile strength, ideal for reinforcement and stabilization.
  • Commonly used in road construction and embankments.

1.2 Geotex Fabric – Non-Woven Geotextiles

  • Made by bonding fibers together (mechanically, thermally, or chemically).
  • Excellent for filtration, drainage, and separation.
  • Often used in drainage systems and erosion control.

1.3 Geotex Fabric – Knitted Geotextiles

  • Combines flexibility with strength.
  • Used in specialized applications requiring both durability and adaptability.

2. Key Functions of Geotex fabric

2.1 Geotex Fabric – Separation:

  • Prevents mixing of different soil layers (e.g., in road construction).
  • Maintains the integrity of materials and improves load distribution.

2.2 Geotex Fabric – Filtration:

  • Allows water to pass while retaining soil particles.
  • Used in drainage systems to prevent clogging.

2.3 Geotex Fabric – Reinforcement:

  • Adds tensile strength to soil, improving stability.
  • Commonly used in retaining walls, slopes, and embankments.

2.4 Geotex Fabric – Drainage:

  • Facilitates the flow of water through or along the fabric.
  • Reduces water pressure and prevents waterlogging.

2.5 Geotex Fabric – Erosion Control:

  • Protects soil surfaces from erosion caused by water or wind.
  • Used in riverbanks, coastal areas, and slopes.

2.6 Geotex Fabric – Protection:

  • Acts as a cushion to protect geomembranes or other structures from damage.
  • Often used in landfill liners and reservoirs.

3. Applications Of Geotex Fabric

3.1 Road Construction:

  • Separates soil layers and reinforces road bases.
  • Extends the lifespan of roads by preventing cracking and rutting.

3.2 Railway Construction:

  • Stabilizes tracks and improves drainage.
  • Reduces maintenance costs and enhances safety.

3.3 Landfills:

  • Used as a protective layer for liners and drainage systems.
  • Prevents contamination and improves waste management.

3.4 Erosion Control:

  • Protects slopes, riverbanks, and coastal areas from erosion.
  • Often used with vegetation for added stability.

3.5 Drainage Systems:

  • Used in subsurface drainage, retaining walls, and sports fields.
  • Ensures efficient water flow and prevents water accumulation.

3.6 Agriculture:

  • Improves soil stability and drainage in agricultural fields.
  • Used in greenhouse flooring and weed control.

3.7 Retaining Walls:

  • Reinforces soil behind retaining walls.
  • Prevents wall failure and improves structural integrity.
