Grids are used to stabilise both paved and unpaved roads |
The grids may be the only practical means of initial site access |
Ground Stabilisation
When these are to be sited over weak or variable ground this poses a challenge
to the engineer. Tensar geogrids provide a high performance solution, which
also meets economic and environmental constraints.
Reinforcement of the granular base layer with Tensar geogrid allows the overall
construction depth to be reduced; saving on materials and excavation.

| Significant saving in granular thickness |
Interlock leads to stabilisation |
When granular material is compacted over Tensar
TX geogrid it partially penetrates
and projects through the apertures creating a strong and positive interlock.
The high tensile stiffness of Tensar geogrids allows load to be developed at
very low strains.
Since 1980, several hundred million square metres of Tensar geogrids have
been successfully incorporated into a wide range of sites under diverse working
and climatic conditions.
The Benefits
Tensar TX geogrids combine major cost savings with considerable performance
benefits in granular capping and sub-base layers
- Savings in granular thickness of up to 40% with no performance loss
- Reduction of excavated soil together with conservation of natural aggregates
- Reduced disturbance and weakening of sensitive subgrade formations
- Improved fill compaction
- Increased design life
- Control of differential settlement
- Spanning of voids
- Very often, making possible the impossible
