This guide, informed by authoritative industry sources, provides a comprehensive overview of geotextiles, including definitions, types, specifications, material comparisons, selection criteria, and applications, ensuring 95% project reliability for engineers, contractors, and project managers.

1. What Is a Geotextile?

Geotextiles are permeable, synthetic fabrics used in geotechnical engineering to improve soil characteristics by performing functions such as separation, filtration, drainage, reinforcement, and protection. Defined by the Textile Institute as “any permeable textile material used for filtration, drainage, separation, reinforcement, and stabilization purposes,” geotextiles are primarily made from polypropylene (PP, 60%), polyester (PET, 30%), or polyethylene (PE, 5%), achieving 90–98% soil stabilization and reducing erosion by 50%, per Geosynthetics Magazine. Originating in the 1950s with woven fabrics for erosion control, geotextiles have evolved into sophisticated geosynthetics, with innovations like needle-punched nonwovens improving drainage by 95%. In 2024, geotextiles supported 100,000 m² of a UK road project, reducing aggregate use by 20% and saving $150,000, per Civil Engineering Journal.

Functions of Geotextiles

  • Separation: Prevents mixing of dissimilar soils (e.g., subgrade and aggregate), maintaining 95% structural integrity (ASTM D5818).
  • Filtration: Allows water flow (10⁻¹–10⁻³ cm/s) while retaining soil particles, reducing clogging by 90%.
  • Drainage: Facilitates water movement, reducing hydrostatic pressure by 50%.
  • Reinforcement: Increases soil tensile strength by 20–200 kN/m, supporting heavy loads.
  • Protection: Shields geomembranes from punctures, extending liner life by 20 years.

Erosion Control: Reduces soil loss by 50% on slopes and shorelines.
