SoilSmart Engineering Ltd is the authorized partner of PRS Geo-Technologies Ltd in Nigeria — the global inventor of the Neoloy® Tough-Cell, a revolutionary three-dimensional honeycomb soil stabilization system made from a Novel Polymeric Alloy (NPA).
Unlike conventional geocells made from HDPE, Neoloy® provides unmatched dynamic stiffness, tensile strength, and creep resistance — the properties demanded by large infrastructure projects. Over 115 professional research papers have validated its performance, and it complies with ASTM, ISO, and international pavement standards.
Since 1996, PRS has deployed Neoloy in 1,000s of projects across 80+ countries — from Arctic tundra to tropical jungles — working alongside engineering giants like WSP, Skanska, Bechtel, the UN, and armed forces of multiple nations.
A three-layer system that transforms weak subgrades into strong, durable infrastructure at a fraction of conventional costs.
The honeycomb cellular structure laterally confines infill soil — even locally available sand or marginal soils — turning weak material into a high-modulus load-bearing layer.
Interconnected Tough-Cells create a stiff semi-rigid slab that distributes vertical loads horizontally, dramatically reducing point pressure on soft subgrades below.
The Novel Polymeric Alloy resists creep, UV degradation, and chemical exposure — maintaining its engineering properties for the full design life of your project.
Works with in-situ sand, recycled aggregate, or marginal soils as infill — eliminating expensive quarried stone imports and dramatically cutting carbon footprint and costs.

From rural feeder roads to international airports, PRS Neoloy® Tough-Cells solve the toughest ground engineering problems — particularly the soft, laterite-rich subgrades common across Nigeria's south and north-central zones.
Highways & Roads
Reinforced subbase layers enable thinner asphalt, lower costs, and 2–5× longer lifespan on soft Nigerian subgrades.
Railway Stabilization
Proven on Amtrak (USA), Israel Railways, PKP Poland, and Transnet (South Africa) — reducing maintenance cycles by 3–7×.
Ports & Wharfs
Heavy-duty platform reinforcement for container yards, cranes, and quay construction on soft, compressible soils near water.
Airfield Pavements
Deployed at the New International Airport of Mexico City and multiple UNOPS airstrips — meeting the highest load-bearing requirements.
Slopes & Embankments
Erosion control and slope protection on motorways and mine sites — up to 55° gradient, with optional vegetation for green aesthetics.
Industrial Platforms
Stabilized working platforms for oil & gas compressor pads, coal stockpiles, and heavy industrial equipment foundations.
Our multidisciplinary team of certified geotechnical engineers, environmental scientists, and structural analysts brings decades of combined experience to every project — combined with the world's most advanced soil stabilization technology as the official PRS Neoloy® partner in Nigeria.
PRS Neoloy® has been deployed on some of the world's most challenging infrastructure projects — delivering measurable results on every continent.
Neoloy Tough-Cells reinforced problematic expansive clay sections of Amtrak's Northeast Corridor, reducing the maintenance cycle 7× compared to conventional methods.

200+ km of feeder roads and airstrip rehabilitation on black cotton soil in remote areas — using local soil infill where aggregate was unavailable. Completed ahead of schedule.
Client: William Muchira, Project Manager, UNOPS
Stabilized extremely problematic soils (including 3m-deep mining holes) for a high-capacity container yard. Improved bearing capacity 6× and reduced concrete layer thickness by 30%.
Client: Balticon & MTM SA
9.2 km strategic road built under fire with 75% less aggregate, using local desert fill. Performance exceeded all expectations. Reduced road cost by 1/3 while saving lives.
Client: Lt. Col. M T G Bazeley, 28 Engineer Regiment
Dual Neoloy layers transformed a failing peat yard (CBR=1%) into a high-capacity heavy operations platform. Estimated annual savings: $750M in production + $250K in fuel/maintenance.
