Load support of roads and railways bases by Tough cells Neoloy and biaxial geogrids

Tough cells Neoloy and Biaxial geogrids are used to stabilize and reinforce road and railway bases. By interlocking with the stone base aggregate, they increase the shear resistance and lateral restraint. The loads are better distributed, and stress concentrations are reduced. Differential settlements are reduced, and bearing capacity is increased.

Load support of road and railway bases by tough cells Neoloy and biaxial geogrids  – advantages:

  • Reduces construction costs for paved and unpaved roads in weak soil

  • Increases soil modulus/bearing capacity

  • Reduces aggregate structural pavement and asphalt layer thickness

  • Retains cell wall stiffness for project lifespan

  • Maintains compaction by eliminating particle movement

  • Allows utilization of local, inferior and recycled materials for infill

  • Reduces long-term maintenance costs

  • Provides sustainable solutions with significant environmental benefits

Other Applications

  • Drainage, separation and reinforcement of sub-bases by geotextile

    Drainage can reduce the negative influence of confined water on the bearing capacity of the base layers. Reinforcement can improve the bearing capacity.


  • Asphalt reinforcement against reflective cracking

    The application of an interlayer between two asphalt layers can retards reflective cracking between asphalt layers.


  • Lining of clay subgrades

    Lining with HDPE Geomembranes enables the clay to maintain a constant moisture content and thus prevent its swelling.
