PRS engineers translate loading, subgrade, available materials, site constraints and design-life requirements into a project-specific Neoloy® Tough-Cells configuration, selecting the appropriate category, cell opening, height and design method for efficient performance.
An optimized design matches the Neoloy® Tough-Cells configuration to the project’s loading, subgrade, available materials, site constraints and performance requirements. Similar projects can require different solutions when these conditions vary.
PRS engineers apply validated design methods and defined engineering parameters to develop the appropriate configuration.
Detailed properties, standards and validation data are available on the Engineering Properties, Geocell Standards and Validation & Research pages.
PRS engineers work directly with the project engineering team through four core stages:
Review loading, subgrade strength, soil conditions, site constraints, available materials, budget and schedule together with the project team.
Select the Neoloy® category, cell opening size and cell height that best match the loading, infill, application and design-life requirements.
Apply the validated design method and relevant engineering factors to determine the required Tough-Cells configuration and reinforced-layer design.
Provide the selected configuration, drawings and design basis required by the project team for approval, coordination and construction.
Neoloy Tough-Cells are configured through three coordinated engineering variables. The optimum combination depends on the application, loading, infill or soil conditions, environmental exposure and required design life.
Selected to match the required strength, stiffness, durability, loading conditions and design life of the project.
Selected in relation to infill characteristics, confinement behavior, loading and the specific application.
Selected according to the required confinement depth, structural configuration, loading and application conditions.

For applicable load-support designs, validated engineering factors are used to translate Tough-Cells behavior into project-specific structural calculations.
The exact factors used depend on the design method and application.
Represents the increase in effective stiffness of the reinforced layer, supporting higher traffic or loading without simply adding more material.
Represents improvement in effective subgrade support, helping engineers optimize reinforced layers over soft or variable ground conditions.
Represents improvement in the reinforced system's load-bearing response, supporting demanding heavy-duty and short-term loading conditions.
The applicable engineering factors are used within the selected design method to determine project-specific layer dimensions, material requirements and structural performance.
The design variables and calculation method change with the application.
Match the Tough-Cells category and reinforced-layer configuration to traffic, loading, subgrade conditions and available materials.
Configure the appropriate Tough-Cells category and geometry for wall configuration, retained soil conditions and long-term structural demands.
Match cell geometry and material configuration to slope angle, soil conditions, hydraulic exposure and required surface protection.
Configure cell height, category and system geometry for hydraulic conditions, lining requirements and environmental protection objectives.
PRS design methods are supported by large-scale moving-wheel testing, field testing, international standards and published research.
