Polypropylene woven geotextiles were the first synthetic forms of geotextiles after those of natural fibres. Originating in the Netherlands in the mid 20th century, they grew fast in applications for coastal, road and embankment and reclamation works. They are weaved from polypropylene tape yarns, mostly Ultra Violet stabilized with carbon black.
The weight range is typically from 120gsm to 500gsm exhibiting a tensile strength of 30kN/m to 100kN/m in a combination of either or both directions. Within this range, the woven polypropylene geotextile is a more economic solution in applications where fine filtration is not anticipated but in place, higher strength with limited elongation is preferred.
Whilst nonwoven geotextiles have an elongation of 50% to 80%, woven polypropylene geotextiles have an elongation between 15% to 30%.
