The Cost of Using Geocell vs Conventional Pavement
Geocell is a cellular confinement system, a 3D geosynthetic for road reinforcement. Looking at the cost of using geocell, this technology can cut aggregate costs by 30%-40% compared with conventional pavement systems.

Geocell product details
Using 8” (15 cm) of sandy soil in geocell can replace 49 cm of sirtu (sand-gravel mix) in a conventional pavement structure, or 67 cm of limestone in a conventional pavement system. So how do the costs compare when using geocell on Java?
Example case: building a 1 km road, 6 m wide, on Java.
- Unit Cost of Geocell Material
15 cm: IDR 65,000/m2 (source: Tokopedia)
Sandy soil infill (t: 15 cm): IDR 21,000/m2 (source: Dunia Pasir)
Total: IDR 86,000/m2
- Unit Cost of Limestone Material (Without Geocell)
Limestone (t: 67 cm): IDR 106,500/m2 (source: Tokopedia)
- Cost Difference
Difference or saving: IDR 20,500/m2
For a construction area of 6,000 m2, the potential saving is IDR 123,000,000.
That is a 20% efficiency in material construction costs. Other aspects should of course also be considered, such as efficiencies in the laying and compaction method, when weighing the overall benefits of using geocell.
