General
Weak or variable ground poses a challenge to the engineer;
geogrids provide a high performance solution, which also meets
economic and environmental constraints. Reinforcement of the granular
base layer with a geogrid allows the overall construction depth to be
reduced, saving on materials and excavation.
The Mechanism of Interlock:
When granular material is compacted over the geogrid it partially
penetrates and projects through the apertures creating a strong and
positive interlock. The high tensile stiffness of the grid allows load
to be developed at very low strains.
The Benefits:
· Savings in granular thickness of up to 40%
· Reduction of excavated soil together with conversation of natural
aggregates
· Reduced disturbance and weakening of sensitive subgrade formations
· Improved fill compaction
· Increased design life
· Control of differential settlement
