Non-reusable used tyres are waste with excellent mechanical properties, which are available in significant quantities in many countries.
Pneusol® involves the combination of two elements: non-reusable used tyres (“pneu”) and soil (“sol”), whether natural, artificial, or filler from other waste. This combination not only recovers large volumes of non-reusable used tyres but also results in a soil (“tyresoil”) with superior mechanical properties.
Pneusol® was patented in 1974 by Dr. Eng. Long Nguyen Thanh, of Vietnamese origin, at the “Laboratoire Central des Ponts et Chaussees” in Paris and has been widely applied since 1982 in hundreds of works in France, Algeria, the United Kingdom, Canada, and even in Romania.
Civil engineering works that use this process involve the construction of:
• support structures with steep slopes (avalanche walls or for preventing landslides)
• lightweight fills (embankments, slopes, foundation soil) that reduce direct pressure by up to 40%
• bank safety systems, various military applications, etc.
Pneusol® Benefits
- Reduced costs for slope stabilization and/or embankment due to the replacement of concrete and/or other materials used for this purpose with waste from used tyres
- Ensures the same durability and long-term stability as classical methods and materials used for slope stabilization, since the vulcanized rubber in tyres has an extremely long self-degradation period.
