More uniform earthworks fill and subgrade layer

Encapsulation and remediation of treated contaminated soils

Dries large volumes of water-logged soil instantly

Addition of moisture to improve load bearing of dry soils

Can be undertaken in any weather conditions

Reduces down-time by enabling earthworks to continue during earthworks shoulder seasons

Enables reduced pavement thickness and improves earthworks fill and subgrade performance

Moisture Conditioning

Moisture conditioning enables large volumes of material to be dried instantly or alternatively to increase moisture of very dry soils to improve compaction. This allows earthworks to continue without delay or risk of quality assurance test failures and rigorous supervision.

Moisture conditioning of wet material using binder is more cost-effective than conventional earthworks drying techniques, and by conditioning wet-of-optimum moisture content soils after a rain episode, earthworks operations can continue immediately, limiting unproductive down-time.

Compared to conventional methods, the use of a stabiliser to add moisture can save up to 50% of the water required and achieve a much more consistent result. In dry remote locations where water is scarce this can provide many benefits.

Earthworks can continue without delay or risk of quality assurance test failures and rigorous supervision.


Hiway Group is committed to delivering solutions with environmental benefits, particularly when considering the treatment of contaminated materials and remediation of contaminated sites to reduce costly excavation and disposal.
