Highways

Highways

TERRAM Geosynthetics are used extensively in the construction of highways in civil engineering applications  - 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

Application Function

Filter separators


Demarcation and warning layers for underlying
contaminants and services
In addition to the filter/separation functions required for construction over contaminated land there is usually an additional requirement to warn operators, during excavation at a later date, of the contaminated land below.

TERRAM Hi-Vis is a bright orange geotextile used to mark areas of contaminated 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.
