High elastic stiffness
Maintains reinforced-layer response under repeated loading, allowing material-efficient pavement designs.
Green construction requires more than selecting a lower-impact material. Civil infrastructure must meet safety, loading, durability, schedule and cost requirements while reducing virgin-resource use, transportation, emissions, waste and site disturbance across the project life cycle.
These objectives become more difficult on weak soils and remote sites, where conventional construction can require excavation, subgrade replacement, thick aggregate layers and repeated maintenance. Sustainable design must therefore combine measurable environmental improvements with reliable engineering performance.
For engineers, contractors, owners and sustainability teams, the challenge is to reduce environmental impact without transferring risk to performance, constructability, maintenance or total lifecycle cost.
Neoloy® Tough-Cells provide 3D mechanical soil stabilization and pavement reinforcement. When the cells are filled and compacted, confinement increases the stiffness of the infill and distributes vertical loads over a wider area, helping protect weak subgrades and reduce deformation.
This reinforced layer can reduce the quantity and quality of imported aggregate required, allow project-approved local or recycled materials to be used as structural infill, and minimize excavation or subgrade replacement. The same technology supports permeable pavements, stormwater channels, erosion-control slopes and vegetated earth structures.
For sustainable infrastructure projects, Neoloy® Tough-Cells can help:
Neoloy® Tough-Cells are manufactured from Novel Polymeric Alloy – NPA, with engineering properties intended to maintain confinement and structural contribution over long project service periods:
Maintains reinforced-layer response under repeated loading, allowing material-efficient pavement designs.
Supports dimensional stability, maintained confinement and longer service intervals.
Resists hoop stresses and lateral movement as loads are distributed through the confined infill.
Manufacturer documentation describes resistance to water, UV, oxidation and naturally occurring acidic and alkaline soil conditions, with no intentional leaching during designated use.
Uses local infill for reinforced earth structures and can reduce the footprint of temporary access through sensitive or remote sites.
Reinforces turf, gravel and permeable paving for parking, shoulders, emergency access, public spaces and low-impact-development areas.
Creates durable construction and service roads for solar, wind, battery-storage and remote energy projects with constrained logistics.
Confines soil, limits erosion and supports vegetation on embankments, channels, riverbanks and rehabilitated landscapes.
Supports drainage channels, bioswales, retention areas and permeable surfaces that promote infiltration and control runoff.
Comparative road studies reported approximately 30–60% less aggregate material than conventional designs.
The same comparative analysis reported approximately 28–42% less total aggregate hauling.
Calculated project comparisons reported approximately 25–58% lower CO2 emissions from aggregate production and hauling.
Project-specific reinforced designs may reduce total pavement structure by up to approximately 70%.
Project-approved sand, marginal granular soils, reclaimed asphalt and recycled concrete can replace part of the virgin imported aggregate.
Weak-soil stabilization can minimize or eliminate excavation and replacement where supported by project design.
Lower material quantities can reduce quarrying, earthworks, haul traffic, equipment use and onsite disruption.
Fewer earthmoving and hauling operations can lower fugitive dust, noise and disturbance around the work area.
Perforated cells and suitable permeable infill can promote infiltration, lateral water movement and reduced surface runoff.
Cellular confinement protects soil and can support vegetated slopes, channels, green walls and landscape restoration.
Temporary access sections may be removed at project completion, with local infill retained onsite and vegetation restored, subject to the restoration plan.
PRS documentation identifies a typical service-life range of approximately 10–75 years or more, depending on design, exposure and project conditions.
Reduced deformation and surface degradation can lower repair frequency, maintenance-related material use and operational disruption.
The installed system itself does not require operational energy or water; normal pavement or landscape maintenance still applies.
PRS provides an Environmental Product Declaration for Neoloy® Tough-Cells as a Type II self-declared environmental statement under ISO 14021. It covers raw materials, manufacturing, project use, reference service life and end-of-life considerations.
Key supporting credentials include ISO 14001:2015 environmental management, ISO 9001:2015 quality management, CE marking and factory production control, plus manufacturer declarations addressing REACH, SVHC and RoHS requirements.
PRS provides an Environmental Product Declaration (EPD) for Neoloy® Tough-Cells, prepared as a Type II self-declared environmental statement under ISO 14021. The declaration consolidates product and lifecycle information that project teams can use during environmental review, material evaluation and alternative-design comparison.
A 23 MWac solar and battery-storage project in Palau required durable unpaved construction and service roads across 16 hectares of savannah. The remote island had a low-bearing sandy subgrade and limited granular resources, while the project team aimed to minimize aggregate use, protect surrounding forest and provide low-maintenance access over a 50-year design life.
Neoloy® Tough-Cells stabilized the subgrade without soil replacement and reinforced a blend of locally available sand, soft volcanic rock and limited limestone aggregate. Folded sections simplified shipping, and remote training supported correct installation by local crews.
