Terram standard geotextiles enhance the performance and design life of granular layers by providing the filtration and separation functions. Typical uses for Terram standard geotextiles include ground stabilisation (between the sub-base and subgrade) and around drainage materials.

Preventing intermixing of granular materials and soils

Terram geotextiles provide an effective solution to the problem of constructing a stable granular layer over soft foundation soils. When stone is placed directly on a soft subgrade, the imposed load often causes intermixing of two layers. This results in contamination of the stone layer and a resulting loss in bearing strength, surface rutting and deformation at the sub-base/subgrade interface.

Preventing the ingress of fines into drainage media

Whether it's a granular drain or a geosynthetic alternative such as open geocellular units, Terram standard geotextiles are ideal for preventing the ingress of fines.

Terram filters/separators are used extensively in the
construction of:

  • Paved and unpaved roads
  • Railways
  • Car parks and hardstandings
  • Cycleways and footpaths
  • SuDS installations
  • Green roofs

TERRAM NGS2, NGS3, NGS4 & NGS5 geotextiles for separation and filtration have gained the NorGeoSpec accreditation through a SINTEF-approved facility. PDF data sheets are available to download below.
