Geocell

News: CSIR-CRRI and BPCL received record recognition for constructing the first roadblock section using geocell made from end-of-life plastic waste.

About Geocell

• Geocell: It is a three-dimensional cellular confinement system used in geotechnical engineering to improve soil stability and load-bearing capacity.
• Structure:
  • Cell Design: Geocells consist of interconnected honeycomb-like cells made from geosynthetic materials such as high-density polyethylene (HDPE) or polyester.
  • Filling Material: These cells are expanded on site to form a mattress-like layer and are filled with soil, sand, aggregate, clay, gravel, concrete, or recycled materials for ground stabilization.
• Working Principle:
  • Soil Reinforcement: Once filled and compacted, the geocell layer integrates with the underlying soil to create a stable and reinforced structure with improved durability and structural integrity.
  • Performance Validation: Extensive material characterization, performance evaluation, and validation studies were conducted to assess the field applicability of the developed geocell system for road applications.
• Applications:
  • Pavement Load Support: Geocells reinforce the soil in the subgrade-based interface or within the base course for road construction applications.
  • Slope and Channel Protection: Three-dimensional lateral confinement along with anchoring techniques ensures long-term stability of slopes, river channels, and embankments using vegetated topsoil, aggregate, or concrete surfacing.
  • Earth Retention and Infrastructure: Geocells are used for constructing steep vertical mechanically stabilized earth structures, airport runways, and urban green infrastructure.
