Neoloy is a Reliable, Green Reinforcement Solution

Chemical stabilizers are costly, not uniform and environmentally unsound. Neoloy® Tough-Cells are cost-effective, green, reliable and long-lasting.

Chlorides and other chemical stabilizers are limited in their effectiveness.  Their performance is unreliable and leaves pavements prone to cracking. Neoloy Tough-Cells provide a durable and uniform reinforcement solution that is easy to apply,  cost-effective and environmentally friendly.

Most native soils require some stabilization to provide a strong base or sub-base for road construction and reinforcement. Various chemicals and compounds are used to stabilize the soil or infill, such as lime and fly-ash mixtures, calcium chloride, cement, epoxy resins, bitumen, lignin sulfonate (“tree sap”) and new polymer materials. But many of these are unreliable in the long-term, expensive and/or not green solutions.

Although Chlorides are most often used a product for soil stabilization, its narrow application range is a major limitation. Too diluted or too concentrated renders treatment of the target soil ineffective. Further, chlorides are harmful to the environment and corrosive on construction equipment. Other additives used for roadbed stabilization are characterized either by poor longevity or environmental toxicity. Products that are environmentally safe and have a favorable lifespan are significantly more expensive. Cement stabilization is expensive but not a green solution.

3D Neoloy Tough-Cells are a more effective soil stabilization solution for road construction. Neoloy offers higher engineering value, lower environmental footprint and is more economically feasible. Furthermore, the installation provides a uniform reinforced layer, as it is not an additive. In addition, its long-term reliable performance is not in doubt as it has been proved in lab and field tests worldwide, including South Africa.

The following summarizes the benefits of Neoloy Tough-Cells over chemical and cement soil stabilization additives:


  • Improves modulus – of infill soil and structural layers
  • Longer lifespan – high resistance to deformation under dynamic loading
  • Performance – very predictable and reliable performance
  • Installation – easy, fast and systematic (with PRS supervision) to guarantee performance
  • Low environmental impact – during construction
  • Green solution – reduces aggregate use and associated environmental costs
  • Sustainable solution – reduced repairs and maintenance due to long pavement life
  • Cost effective – lower construction costs and lifecycle costs
