Slopes and Channels

Erosion Control For Slope and Channels

Tough Cell’s honeycomb, perforated yet durable 3D structure is extremely efficient for controlling soil erosion, enabling drainage and stabilizing slopes. It provides long-lasting and effective steep slope stabilization for soil erosion control; all soil stabilization needs for slope protection are met and can be custom designed and matched specifically to every project. Tough Cells can be infilled with soil and vegetation, with granular non-cohesive infills or in cases of high velocity water flows -with concrete. The chosen fill can be customized – in accordance to the nature of the project’s hydraulic conditions and/or the global stability and soil makeup of the construction site. Tough Cell advanced three-dimensional earth confinement system is the best solution for channel and shoreline erosion caused by streaming water.
Designed to enhance friction resistance to prevent soil migration, the Neoloy material that Tough Cell is constructed of grants durability to harsh environmental conditions, such as very high temperatures, oxidation and UV radiation. Structurally suited for optimal water drainage, Tough Cell Geocell slope stabilization solution is also based on flexible structural design that endures earth movements while maintaining structural integrity for a long lasting life span.

Subsequently, Tough Cell slope stabilization methods guarantee durable, proven solutions for slopes while offering various cover options, determined by the project’s nature, channel geometry and hydraulic conditions, including:

Topsoil – Landscaping
One of the Tough Cell slope stabilization methods, makes use of local soil as infill. Tough Cell’s perforated wall design encourages plant growth, thus creating an interlock by using the rooted soil to ensure even greater root mass reinforcement. The same perforations optimize water drainage by limiting hydrostatic buildup. Using topsoil protects the environment and is a cost-effective solution that are more effective solutions than riprap, gabions or erosion control blankets.
Note: This solution is suitable for up to 6.5 m/sec flow velocity.

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.



Less project maintenance and optimized cover surface infills results in lower lifecycle costs.

Erosion Protection

Tough Cell Geocell slope stabilization cells use soil confinement to protect banks from runoff and enhance soil structure ending in a successful limitation of hydrostatic forces.


Tough Cell perforations enhance drainage capabilities and maximize infiltration, while vegetation provides plant root interlock and limits the impact of hydrostatic forces.


Simple and quick installation, in addition to the possibility of using local non-cohesive soils as infill, the Tough Cell itself provides the formwork for concrete infilled sections.


Enhance growth and soil health - all while enabling free, controlled water flow and sustaining a natural landscape, Tough Cell is a guaranteed green solution.


Durable Neoloy technology ensures long term resistance to a wide temperature range, UV radiation and oxidation.
