Writing a complete Non Woven Geo Textile specification ensures the supplied fabric actually performs the function the designer intended.
A typical tender specification should call out: polymer (polyester or polypropylene), weight per unit area (g/m²), tensile strength (kN/m, machine and cross direction), CBR puncture resistance (N), apparent opening size (microns), permittivity (s-1), thickness, UV resistance, and acceptable test methods.
Application-specific tweaks: for separation between sub-grade and sub-base emphasise CBR puncture and grab tensile; for filtration behind walls and drains emphasise permittivity and opening size relative to soil grading; for drainage in landfill or capillary breaks emphasise transmissivity and in-plane flow; for protection for geomembranes emphasise CBR puncture and thickness.
Documentation required at supply: mill test certificates, manufacturer's data sheet, batch traceability and applicable approval certificates. MORTH Section 700, IRC: SP: 59 and IS 16391 are the typical Indian references.
