Protection geotextiles prevent the damage of other construction layers, materials and products (for example lining membranes).
Nonwoven geotextiles manufactured from staple fibres by needle punching technology are most commonly used as a protection layer.
Key properties of protection geotextiles:
Tensile strength - EN ISO 10319
Elongation - EN ISO 10319
Static puncture test (CBR test) - EN ISO 12236
Dynamic perforation test (cone drop test) - EN ISO 13433
Pyramid puncture resistance - EN 14574
