Long-Term Wall Stability
High tensile strength keeps the wall confined under sustained earth pressure.
Fast, Durable and Green Earth Retention with Neoloy® Tough-Cells
Retaining walls and earth stabilization systems must control soil movement from lateral earth pressure, surcharge loads, weak foundations, poor drainage, seismic forces, and long-term exposure.
The challenge goes beyond the visible wall face. A successful design also accounts for slope geometry, foundation capacity, groundwater, deformation control, material durability, and site access. Miss any of these, and the project risks settlement, wall movement, drainage failure, or a shorter service life.
Conventional concrete, gabion, and segmental block walls retain soil effectively, but they often demand deep excavation, imported materials, heavy equipment, and long build schedules.
A durable earth retention system should do more: maintain confinement, control deformation, support drainage, adapt to site conditions, and hold structural integrity for its full design life.
Neoloy® Tough-Cells mechanically stabilize retaining wall structures through confined horizontal layers. Each layer is filled and compacted to create a stable reinforced block. The cellular structure confines the infill, resists lateral movement and helps the wall behave as a unified mass.
The system improves earth retention performance through:
Long-term earth retention performance depends on tensile strength, creep resistance and dimensional stability, especially because retaining structures are exposed to sustained loads over time.
Neoloy® earth retention translates material performance into structural value.
High tensile strength keeps the wall confined under sustained earth pressure.
Low creep keeps cell geometry stable, so the wall keeps its shape for years.
NPA holds its stiffness under sustained load, even at elevated temperatures.
Material properties are proven to meet the wall's full service-life requirement.
The flexible wall mass absorbs seismic energy and tolerates minor ground movement.
Panels unfold on site and stack directly into a stable structure.
Validated local or waste materials can fill the cells, cutting import costs.
Green fascia and local infill cut imported materials, hauling, and overall footprint.
Road and rail embankments require stable earth structures that resist erosion, settlement and slope movement. Neoloy® Tough-Cells can support green embankment walls, grade transitions, bridge approaches, transportation corridors and safety barriers.
Gravity retaining walls use the self-weight of stacked Neoloy® Tough-Cell layers and compacted infill to resist lateral earth pressure. This configuration is suitable for lower to moderate wall heights, landscape walls, infrastructure slopes, embankments and green retaining structures.
Integrated earth stabilization combines a Neoloy® retaining wall at the base with Neoloy® slope protection on the upper slope. This is especially relevant for unstable, steep or high slopes created by road construction, cut-and-fill earthworks or failed slopes.
For energy, industrial and storage infrastructure, Neoloy® Tough-Cells can be used to build protective berms and retaining walls around tanks, facilities and sensitive assets.
Where flat construction space is limited, retaining walls are often required to create level platforms for industrial sites, yards, buildings, tanks or infrastructure facilities. Neoloy® Tough-Cells can form earth retention structures that extend usable space and stabilize the platform edge.

A Caribbean refinery expansion required a level platform for new LNG storage terminals, increasing capacity by 400,000 barrels, or 33%. Conventional concrete and gabion walls were constrained by seismic design requirements, high costs, and difficult material logistics.
PRS delivered a free-standing Neoloy® Tough-Cells gravity wall using quarry waste as backfill and native vegetation for the fascia. The 300 m-long wall, reaching 6.5 m in height, was completed within three months.
