About Geocell
- A three dimensional cellular confinement system used in geotechnical engineering
- Designed to improve:
- Soil stability
- Load bearing capacity
- Structural reinforcement
Structure of Geocell
- Consists of interconnected honeycomb shaped cells
- Made from geosynthetic materials such as:
- High Density Polyethylene (HDPE)
- Polyester
Working Mechanism
- Cells are expanded on site to form a mattress like layer
- Filled with materials such as: Soil, Sand, Aggregate, and Clay
- After compaction:
- The geocell integrates with underlying soil
- Creates a reinforced and stable structure
