Overview

TERRAM Geotextiles are trusted by the industry to separate granular layers of stone on a range of civil engineering and building applications, such as highways, roads, car parks and railways, among others. TERRAM Geotextiles are permeable to filter water, but stop particles from mixing with other layers, thus extending the life of the structures.

Frequent Problems

TERRAM geotextiles prevent the intermixing of the sub-base and subgrade layer in civil engineering and building applications.

Previous

Ground Filtration and Separation

  • No intermixing of sub-base and subgrade layers
  • Sustained filtration between layers while providing separation
  • Extended life structure

With Terram Geotextiles

  • No intermixing of sub-base and subgrade layers
  • Sustained filtration between layers while providing separation
  • Extended life structure

Sub-base and subgrade layer intermixing

Liable to ground deteriation, especially with poor weather Traditional solutions can cause surface water run off, and remove natural drainage Solutions may require re-working off the whole area, which can be costly and unnecessary

Without Terram Geotextiles

  • Stone layer contamination causes a loss in bearing strenght
  • Deformation of the pavement surface in paved and unpaved roads
  • Repairing of the damage requires a complete reconstruction, which can be costly and doesn’t always fix the structural damage
  • Low-cost woven textiles with little integrity won’t prevent intermixing
