Geocells are three-dimensional, honeycomb-like structures made from polymer materials, typically high-density polyethylene (HDPE). They are used to confine soil, aggregate, or other fill materials to enhance their load-bearing capacity and improve overall stability.
History and Development
The concept of Geocell manufacturers in India dates back to the late 1970s when the US Army Corps of Engineers developed them to stabilize sand roads for military purposes. Over the decades, geocell technology has evolved, leading to widespread adoption in civil engineering and environmental protection projects worldwide.
Technical Specifications
Geocells are characterized by their cell size, depth, and material thickness. These parameters can be customized to meet specific project requirements. Standard geocell sizes range from 100mm to 300mm in cell diameter and 50mm to 200mm in cell depth.
Types of Geocells
HDPE Geocells
High-density polyethylene geocells are the most common type due to their durability, flexibility, and resistance to environmental stressors.
Non-Perforated Geocells
Non-perforated geocells provide maximum confinement and are ideal for projects requiring high load support.
Perforated Geocells
Perforated geocells offer better drainage and are used in applications where water management is crucial.
Textured Geocells
Textured geocells enhance the friction between the geocell and the infill material, improving stability.
Applications of Geocells
Road Construction
Geocells are extensively used in road construction to reinforce the base layer, distribute loads, and reduce the thickness of the pavement layers.
Slope Protection
Geocells help stabilize slopes and prevent soil erosion by confining the soil and vegetation.
Retaining Walls
Geocell retaining walls offer a cost-effective and environmentally friendly alternative to traditional retaining structures.
Load Support
Geocells distribute loads over a wider area, making them ideal for supporting heavy structures such as airport runways and parking lots.
Erosion Control
Geocells are effective in preventing erosion in channels, riverbanks, and coastal areas by stabilizing the soil and promoting vegetation growth.
Channels and Basins
Geocells provide structural integrity to channels and basins, enhancing their ability to manage water flow and prevent erosion.
