Excellent high quality geotextile

Naptex® is a non-woven geotextile, thermally welded, 100 % propylene. It is a material of a wide application range. Owing to an excellent combination of high initial modulus and high elongation (up to 50 %), as well as a unique structure, it demonstrates superlative mechanical properties in all directions.


  • High energy absorption capacity
  • High initial rigidity modulus
  • High elongation at rupture (up to 50%)
  • Long lasting filtration (resistance to clogging)
  • High material structure homogeneity
