Non-woven geotextiles are manufactured from polypropylene staple fibres, using needle-punching technology. In order to improve mechanical-physical characteristics of the material, surface of some particular types is odified by calendering (thermal bonding).
Non-woven geotextiles are resistant against the actions of microorganisms, fungi and moulds, simultaneously offering resistance against wide range of chemicals.
