Ground Stabilisation
Ground stabilisation can be a challenge for engineers, when the structures listed above are to be sited over weak or variable ground and Tensar geogrids are high performance solutions to these challenges, which meet environmental and economic constraints.
To save on excavation and materials, a reinforcement of the granular base layer with a Tensar geogrid allows the overall construction depth to be
reduced.

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