NON-WETTING SOIL STABILISATION
A local Government Shire in Western Australia was recently having trouble with a non-wetting silty sand/gravel that was sourced locally to complete a 6km section of unsealed road. Before the introduction of PolyCom, this soil was taking over 600,000 litres per 200m section to achieve OMC and was extremely difficult to work according to the works crew.

The problem: unsealed roads fail through surface wear, most significantly when the 'sheeting layer' disappears slowly in a cloud of dust. Because of this, material loss unsealed roads are a large consumer of natural materials (Centre for Pavement Engineering Education).

The root cause of most roadway failures is drainage, drainage, drainage. John MacAdam said in 1820, "Experience has shown that if water passes through a road and fills the native soil, the road whatever its thickness, loses support & goes to pieces."
