Non- woven geotextiles are permeable, felt- like fabrics made by bonding polypropylene or polyester fiber (e.g., via needle- punching or heat- bonding) to create a flexible, cushioning, and drainage- friendly material. They're widely used for filtration and drainage, allowing water to pass while retaining soil particles ideal for Subsurface drains, French drains, and Retaining walls. These fabrics also provide soil separation, preventing fine subgrade soils from contaminating coarse aggregates in roads, railways, and embankments. Additionally, Non- woven offer moderate reinforcement and erosion control, reinforcing slopes and embankments and protecting geomembrane liners in landfills.
