The geocell is a three-dimensional grid cell structure formed by reinforced HDPE material with ultrasonic welding. It expands into a three-dimensional network during installation. For engineering versatility, the diaphragms are often perforated to enhance drainage and soil interlocking.
This honeycomb restraint system provides strong lateral restraint and stiffness when filled with materials such as sand, stone, or concrete, significantly improving the load-bearing capacity of the ground.
