Terram standard geotextiles can be used to provide ground stabilisation in the construction of roads and hardstandings, and filtration within granular drainage and SuDS systems.
The standard geotextiles are available in a range of tensile strengths and permeability characteristics. The range also includes NorGeoSpec accredited geotextiles (product grades NGS2, NGS3 and NGS4).
Composition and manufacture
Nonwoven geotextile manufactured from UV stabilised, high tenacity, virgin polypropylene fibres, by mechanical and thermal bonding.
