Geotextiles and geotextile-related products

European standards

ASTM standards

Non-woven geotextiles geoNETEX are manufactured in compliance with harmonised European standards:

EN 13249, EN 13250, EN 13251, EN 13252, EN 13253,
EN 13254, EN 13255, EN 13256, EN 13257, EN 13265.

When applied in engineering projects, they perform the functions of FILTRATION (F) and/ or SEPARATION (S) and/ or PROTECTION (P) and/ or DRAINAGE (D).
