Cellular Confinement

Cellular confinement

Strengths of Cellular Confinement

The confining cell structure imparts an effective cohesion to the infill material, thereby increasing its shear strength and stiffness. 

This improvement results from the hoop strength of the cell walls, the passive resistance of the adjacent cells and the high frictional interaction between the infill and the cell walls.

The cell wall structure shows improved lateral load spreading as the result of increased wall-infill interface friction. 

The blocks create a flexible structure bridge system of increased stiffness. 

The structural bridge results in significant improvements in the long-term performance of the load support system and helps to reduce the thickness of structural support elements.

The advantages of using cellular confinement system (geocells) for singlelayer road bases, yards or paved surfaces is the reduction of costs of ground works and infill materials. 

The cellular confinement system enables also the application of less expensive on-site aggregate infill in place of more costly imported materials. 

As loads are distributed through the structural bridge over the soft subgrade, the thickness and weight of structural support elements can be reduced by 50% or more in comparison to the conventional load support.
