Highways

Terram Geosynthetics are extensively used in civil engineering in the construction of highways - from preventing intermixing of sub-base and subgrade layers, control erosion on cut slopes, for roadside drainage, as part of SUDS projects for infrastructure access and in the construction of retaining walls, bridge abutments and steep slopes.

Demarcation and warning layers


Demarcation and warning layers for underlying
contaminants and services
If the filter/separation functions are required for construction over contaminated land then there is an additional benefit that TERRAM products can provide – high visibility so that they also warn operators during excavation at a later date.


TERRAM Hi-Vis is a bright orange geotextile used to mark areas of soil prior to backfilling. Manufactured using orange fibres, it has the same filter/separator benefits of TERRAM Standard Geotextiles but provides a visible separation of clean and contaminated soils. Future excavations will see the visible barrier of the contaminated soils beneath.


TERRAM Indicator Mesh is available in red to protect bridge deck membranes and also act as a depth marker during re-surfacing operations. The mesh is a proven alternative to using red sand and is much easier to install.


TERRAM Detectamesh detectable underground warning tapes, provide two functions when installing highway pipelines, drainage, cables and communication fibre optics: 1; Provides a visible warning to future excavators of the utility service beneath. 2; Contains a traceable element to enable the detection of plastic pipes and un-energised cables using a cable avoidance tool, preventing damage to the services.
