The search for the most beneficial geotechnical engineering solution can lead to several geosynthetic options. Read on to discover what makes Tough Cell Neoloy based geocells the ideal reinforcement method available for a multitude of projects - in any weather condition - in any corner around the world.
Tough Cell’s 3D confinement structure triumphs 2D products, such as geotextiles and geogrids, and its stability provides long term assurances for a more durable construction method than most other conventional ground stabilization solution.
Tough Cell Vs. HDPE Geocells
HDPE (High-Density Polyethylene) geocells are suitable for use in low earth retention structures, soil erosion control and similar applications, but when searching for a base reinforcement solution - they lack sufficient durability.
Tough Cell made of Neoloy, on the other hand, is designed to be a superior polymeric alloy, meant for reinforcement and load support for all heavy-duty applications.
The basic confinement and structure concepts are similar in both HDPE and Neoloy based geocells, but the main factors that influence reinforcement capabilities were studied by researchers all over the world; findings point to Tough Cell as that with the clear advantage. See Published Research
Different materials were put to the test against various parameter testing, including full scale moving wheel tests, plate loading box tests and field demonstrations comparing the HDPE to the Neoloy geocells. The results have shown that performance is significantly better when the elastic modulus is higher- resulting in a significantly better long-term bearing capacity. All of these parameters make Tough Cell's Neoloy solution the best geocell choice for all engineering applications that require a long-term stabilization and reinforcement solution.
Tough Cell Vs. Geogrids
Geogrid is a 2D geosynthetic product that requires high quality, angular, granular fill, such as gravel as a structural infill for road reinforcement. The difference in the geotechnical 2D structure in comparison to the Tough Cell 3D structure leads to various differences in layer thickness, required infill material and long-lasting durability.
The 3D structure of the Tough Cell diminishes soil movement, therefore creating a larger reinforced zone of influence (~40cm below and above height of the cell walls), providing reinforcement to the surrounding material. The non-cohesive fill achieves characteristics of higher quality fill due to 3D confinement interlocking. Geogrids require a specific angular aggregate with size limitations that are not necessary when using Tough Cell.
Another important difference concerns layer thickness. KOAC-NPC (Netherlands) conducted field trial demonstrations in which Tough Cell was the only geocell tested along with 7 other geogrids regarding thickness of structural pavements. The road base thickness reduction factor (CBR=1.5) for Tough Cell was 0.73 by CROW methodology. None of the geogrids tested have shown a better value. In addition, Tough Cell had the highest reduction factors.
