1. What Is Geotextile Drainage Fabric?

Geotextile drainage fabric is a permeable, synthetic textile engineered to facilitate water flow while retaining soil particles, making it ideal for landfill leachate management, filtration, and separation. Typically made from polypropylene (PP) or polyester (PET), these fabrics are produced through needle-punching (80% of nonwoven applications) or thermal bonding (15%), creating a felt-like structure with high permeability (100–150 gpm/ft²) and moderate tensile strength (80–425 lbs), per ASTM D4491 and D4632. In landfills, they prevent 50% of clogging in drainage systems and extend geomembrane lifespans by 20–30 years, per Geosynthetics Magazine (2024). Used in 65% of U.S. landfill projects, they ensure 95% filtration efficiency, per bpmgeosynthetics.com (2025).
