Many work sites across the globe have limited accessibility due to huge areas covered with soft soils, meaning that the terrain cannot provide sufficient load support. Typical load support applications include reinforcement of base and subbase layers in flexible pavements, including: asphalt pavements, unpaved access, service and haul roads; military roads, railway substructure and ballast confinement; working platforms and so on.Read more
Neoloy® Geocell Reinforcement in Load Support Applications. Neoloy is used for soil confinement, stabilization and reinforcement in a wide variety of load support and civil engineering applications, such as base reinforcement in paved and unpaved roads.
Neoloy enables the use of Neoloy Geocells for long-term load support infrastructure projects such as paved roads, railways and multi-modal ports. Geocell with Neoloy maintains its engineering characteristics and geometry for the project lifespan, even under dynamic loading, thermal cycling and high temperatures.
The 3D vertical zone of influence enables the use of poorly graded and fine granular materials, including local native soils, quarry sands, and recycled asphalt or concrete/cement rubble for heavy load support applications such as heavy traffic pavements and railway substructures.
Even a layer of Tough Cell geocells improves the bearing capability by creating a beam-effect. In extreme cases (e.g. CBR < 0.5%) another layer can be added as a sacrificial layer to help support the structure. . This effect acts as a semi-rigid mat, ensuring that swelling or seasonal changes, have little influence on the upper layers. In addition, the mechanical structure of the Tough Cell, along with the beam effect, distributes vertical stresses evenly, therefore enabling much greater load support.
To fine-tune and guarantee technology and safe construction scenarios, the MIF (Modulus Improvement Factor) of the Tough Cell structure was studied in the lab. During this time, it was proven to increase infill strength by 2-5 times, making it the best solution for heavy load support applications.
In conclusion, it’s a fact that soft soils with high water content or highly grained materials cause an engineering challenge. Other existing conventional solutions are very costly.
The Tough Cell is a proven, efficient and cost-effective solution for the transport of heavy haul equipment, while guaranteeing sufficient load support for your project – anytime, anywhere.

Alternative solutions to create a uniform layer called for extensive subgrade replacement with a thick capping layer of quality aggregate. This solution was not cost-effective and does not deal with the high water table. Cement stabilization is too difficult to apply uniformly, its reliability over the long-term is questionable even in unsaturated conditions. Geogrids can not provide the same level of ground reinforcement and require imported higher cost aggregate.
The Tough Cell structure enhances a multitude of infill material behavior, successfully enabling the use of:
Concrete – Containment and treatment ponds. Using concrete is fast and efficient. The Tough Cell is laid in ready-made forms and finished with hard-armor in a uniform thickness – for the best results for every environment.

Granular – Shorelines and Landfills
Natural river banks and shorelines sometimes need riverscape engineering to protect them from erosive forces. By using crushed stone or gravel infill, Tough Cell provides effective protection for slopes/channels and shorelines that are exposed to hydraulic forces, such as ice, wind and water. In addition, Tough Cell can provide geomembrane protection in reservoirs. And landfill drainage systems.
Note: This solution is suitable for up to 3.5 m/sec flow velocity.
Hard Armor – Drainage Trenches and Channels
Tough Cell offer cost-effective, long-term slope protection for channels and road drainage ditches. Use of concrete infill is the preferred choice when dealing with high flows and stresses, such as bottom highway slope trenches where storm water causes intensive run-off. In channel retention cases, only cells subject to high flow rates are filled with concrete while other cells can be filled with granular crushed stone.
Note: This solution is suitable for up to 13.0 m/sec flow velocity.
