The standard Terram geotextile is typically used in ground stabilisation (between the sub-base and subgrade) and around drainage materials to enhance the performance and design life of the granular layers by providing the filtration and separation functions. 

Preventing granular materials and soils from mixing

When stone is placed on top of a soft subgrade, the load often causes intermixing of the two layers. This results in the contamination of the stone layer which can lead to a loss of bearing strength, causing the surface to rut and deformation at the sub-base/subgrade interface to occur.

Terram geotextiles provide an effective solution to this problem allowing the construction of a stable granular layer over soft foundation soils. 

Preventing fines entering into drainage media

Standard Terram geotextiles are perfect for preventing fines entering into granular or geosynthetic drains, such as open geocellular units.

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
