Neoloyยฎ Tough-Cells โ€“ the Smart Innovation in Cellular Confinement Systems

Making Cellular Confinement Systems with Long-term Strength for Todayโ€™s Demanding Transportation and Infrastructure

What is a Cellular Confinement System?

A 3D cellular confinement system is a honeycomb geocell created by the 3D interaction of soil, cell walls and geometry. Cellular confinement systems maintainย  soil compaction, thereby increasing the structural strength of the infill and pavement layer.

The key geocell reinforcement mechanisms are lateral and vertical cellular confinement, beam effect and improved load distribution. When the confined soil within a geocell is subjected to loading, it causes lateral stresses on the cell walls. The 3D zone of cellular confinement reduces the lateral movement of soil particles while vertical loading on the contained infill results in high lateral stress and resistance on the cell-soil interface.

The high-strength geocellย mattress created byย Neoloy-based Tough-Cells, acts as a flexible beam, which reduces stress and settlement. In addition, cellular confinementย increases the elastic modulus values of granular infill materials, particularly marginal fill, such as fine granular soils and recycled materials.

These mechanisms highlight the importance of geocell tensile strength, & elastic stiffness and creep resistance critical differences between PRS-Neoloy Tough-Cells and other HDPE based Soft-Cells.
