Moisture conditioning of earthworks for industrial and commercial developments
Rehabilitation of existing pavements
Significantly improved subgrade stability with strength gains of up to 20 times
Fewer transport costs and faster construction time through the reuse of existing in-situ materials
Reduces risk of costly earthworks fill and subgrade pavement failures
A robust durable platform that eliminates the need for cloth/grid or imported aggregate
Substantially reduces moisture susceptibility
Reduces plasticity making soils easier to work
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 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.
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.
