Soil Recycling

Using the world-class Reterra soil stabiliser, Hiway Environmental offers customers a cost effective and environmentally sound way to treat materials and improve soil performance. Hiway Environmental owns and operates the only two Reterra recyclers in New Zealand.

The Reterra is a purpose-built, mobile soil stabilising and conditioning machine that outperforms conventional stabilisation methods. A fast, efficient way to deal with a wide range of scenarios, the Reterra recycles soil for improved performance, remediates contaminated soil and manufactures binder treatment aggregates.

A mobile machine, the Reterra significantly lowers costs by reducing the reliance on labour, transport and landfill. Internationally, stabilisation and solidification of soils and granular materials is regarded as a proven way to treat or improve the engineering or chemical properties of in-situ unsuitable materials. Hiway Environmental has brought the latest technology to New Zealand for a cost effective, environmentally sound solution to what is often a costly geotechnical problem.
