Geotextiles are permeable fabrics which offer a cost-effective engineered alternative for scarce and difficult to locate natural construction materials. Geotextiles are used in many applications such as drainage, filtration, separation and soil reinforcement, while often being used to improve the performance of civil engineering and construction projects including roads, railways, and landfills
tunnel geotextile fabric features
- High extensibility and extremely robust to resist installation and in-service conditions
- Wide widths for minimum overlap (6m wide - 5.9m for export) saving on overlap wastage
- Very high permeability at all strains with negligible uplift in wave conditions
- Very good sand tightness at all strains retaining subsoil without washout
