Geocells – Cellular Confinement System

Cellular Confinement System such as Miracell, Terram, StrataWeb, Geoweb

Geocell Cellular Confinement System stabilising a road

A Cellular Confinement System (Geocell) is made of lightweight, flexible, three-dimensional, expandable panels engineered from High Density Polyethylene (HDPE) strips and ultrasonically welded for maximum performance.

When infilled with compacted soil, concrete, sand or gravel, geocells reduce soil erosion caused by the lateral movement of particles. As pressure is applied to the soil, the tensile stress on the cell wall increases. The walls of the geocell are textured to increase soil‐geocell wall friction. The depth of the cells, size of each cellular unit and whether or not the sides are perforated depends on the design requirements. Perforations ensure that cells do not become water logged and cause the infill to lose its strength.

Geocell Applications

Cellular Confinement Systems (CCS) are widely used for erosion control and slope protection, load support, ground stabilisation and protecting channels from erosion. A soil slope reinforced with geocells creates a solid base that distributes the load over a wider area, reduces settlement of soft soil, improves shear resistance and load carrying capacity, and reduces distortion. Geocells help vegetation to establish and create surfaces that are easily maintained.

  • Erosion control
  • Load support – hard pads for heavy equipment, road and rail support
  • Slope protection
  • Channel protection
  • Retaining walls
  • Ground stabilisation
Geocell Installation

To minimize transport costs, geocell panels are folded flat and stored on pallets. During installation the panels are expanded to form cells. The sections are filled with material such as soil, sand, aggregate or recycled concrete, and then mechanically compacted. Where it is important to separate a clay substrate from a gravel fill, a geotextile can be laid beneath the geocell.
