What is puncture resistance?
The relative ability of a geotextile to resist objects or stones from bursting or pushing through the material. TERRAM nonwoven geotextiles have a high puncture resistance essential to resist construction damage during installation and placing of fill material with compacting equipment. Woven geotextiles generally have much lower puncture resistance and often (unseen) damage occurs during installation resulting in reduced performance or failure in the longer term. Static puncture resistance consists of pushing a 50mm diameter plunger through the geotextile and is measured in kN (higher is better). Dynamic puncture resistance consists of dropping a cone into the geotextile and measuring the size of the hole in mm (lower is better).
