Geo Cell and Geo Grid are both soil reinforcement systems, but they work through different mechanisms and suit different problems.
Geo Grid: planar reinforcement, two-dimensional, works through tensile strength and interlocking with the aggregate above. Best for sub-base reinforcement, retaining walls, embankment basal layers and pavement layers.
Geo Cell: three-dimensional cellular structure, works through confinement of the infill material. Best for very soft sub-grades, steep slopes, channel lining, tank pad support and applications where vertical load distribution matters more than lateral tensile resistance.
When to choose Geo Grid: standard pavement sub-base reinforcement, normal earth embankments, walls under 6 metres, applications where aggregate quality is good.
When to choose Geo Cell: very weak sub-grades (CBR less than 2 percent), steep slopes (1V:1.5H and steeper), where you want to use lower-quality local infill instead of imported aggregate, channel and erosion protection.
Often the right answer is both: Geo Cell over very weak ground, capped with a Geo Grid reinforced sub-base. Auroguard supplies both and provides combined-system design support on complex sites.
