Tough Cell vs. The Others
Research by the University of Kansas and the Indian Institute of Technology, Madras, comparing Tough Cell to HDPE-based geocells / geowebs has shown that Tough Cell’s construction provides superior benefits.
Tough Cell provides:
- a higher elastic modulus
- greater improvement in terms of stiffness
- greater load bearing capacity
- superior stress distribution
- reduced deformation
HDPE geocells are typically used for soil erosion control in slope and channel protection applications, and as low earth retention structures, but their use in base reinforcement and load support applications is often limited to low volume roads and temporary pavement structures, because they can often lack the necessary stiffness and durability.

Tough Cell geocells have a higher tensile stiffness and strength, and are more durable over time and under elevated temperatures than HDPE geocells / geowebs. This makes Tough Cell a more cost-effective solutions for long-term, low maintenance solutions.
Watch some videos of how Tough Cell is applied to work pads, paved roads, and unpaved roads.
Tough Cell vs Geogrid
Tough Cell creates a reinforced mattress with a beam effect when applied to unbounded base material. Compared to 2D geosynthetic products, such as geogrids and geotextiles, geocell confinement in three dimensions reduces the lateral movement of soil particles. This results in a higher locked-in confining stress and thus a higher modulus of the base.
Conventional ground stabilization solutions (soil replacement, soil cements, or thicker base layers) either do not provide sufficient long-term stability and strength for transportation engineering, and/or entail higher costs and environmental impacts.
