Cellular confinement systems, also called geocells, are commonly employed in the construction industry for a variety of purposes, such as erosion control, soil stabilization on both level and inclined terrain, channel protection, and structural reinforcement for both load-bearing and earth retention. These systems typically consist of geosynthetics made from ultrasonically welded high-density polyethylene( HDPE) or a novel polymeric alloy ( NPA), which are then expanded on location to create a honeycomb-like structure and subsequently filled with materials such as sand, soil, and rock, gravel, or concrete.
Geocell reinforcement is a technique for fortifying soil by utilizing a three-dimensional cellular confinement system. The system comprises high-density polyethylene (HDPE) sheets that are fused together to generate a honeycomb-like configuration. This configuration is subsequently filled with soil, gravel, or other granular materials to form a reinforced soil composite. The cells of the geocell act as a confinement system, obstructing the soil from shifting or eroding. This renders it an efficacious remedy for fortifying slopes, retaining walls, and other edifices that are susceptible to erosion or instability.
Geocell reinforcement is used in the construction of highways. The reinforced soil mass created by the geocell system is commonly used to support the weight of the roadway and prevent cracking and erosion.
Geocell reinforcement is also used for crack prevention in existing roads. The geocell system can be installed over the existing roadway, and the soil or other materials used to fill the cells are compacted to create a reinforced surface.
Geocell reinforcement is also utilized in the construction of airport runways and taxiways. It is used in other civil engineering projects such as dams, canals, riverbank stabilization, reinforcing embankments, and cut slopes, for example, in the construction of railway tracks. It not only provides support but also prevents cracking and erosion.
Geocell reinforcement is required, mostly in the construction of landfill and waste management facilities. It helps to prevent the leakage of leachate and other hazardous materials.
Geocell reinforcement is also used in the construction of green roofs and roof gardens; it helps supports the weight of the plants and other materials used in the green roof.
