Geocells are lightweight, expandable cellular confinement made of high-density polyethylene strips that are expanded on-site to form a honeycomb-like structure.
When infilled with compacted soil, geocell creates a new composite entity that possesses enhanced mechanical and geotechnical properties. The 3D zone of confinement reduces the lateral movement of soil particles due to the stresses induced by incoming loads and increase the shear strength of the confined soil, which in turn creates a stiff mattress or slab to distribute the load over a wider area, increases shear resistance and bearing capacity, decreases the deformation and therefore provides efficient slope protection.
Geocells with multiple layers of geocells filled with granular material stacked on top each other make effective gravity walls. Their perforations ensure that hydrostatic pressures behind the wall are dissipated.
• They are easily transported as flat strips welded width‐wise at regular intervals, and hence large quantities is not a problem.
• Easy to install and do not require skilled labour and can be installed in any weather condition.
Geocells are widely used in construction for erosion control, soil stabilization on flat ground and steep slopes, channel protection, and structural reinforcement for load support and earth retention.
