October 2021

Scope of Work

Dowsing Group client, NA Group, provide a 24/7 emergency response service for road related incidents throughout Sydney and required urgent road profiling rehabilitation services due to a truck spillage incident on the M4 Motorway. The incident created a hazard for road users due to loss of traction on the road surface from the clay spillage over multiple lanes on the busy motorway.

Dowsing Group were called at 4:30pm on Saturday and quickly mobilised two 2m Profilers and four operators to the site within the hour.

The scope of works included the following:

  • Profiling of road pavement at a depth of 45mm for two traffic lanes of 4km long and select sections of the third lane


Road profiling was the quickest and most cost-effective solution to remove the layer of clay to rehabilitate the road and our reactive capabilities and resource capacity enabled NA Group to effectively manage the incident response. The emergency road profiling works across two lanes of the M4 Motorway took four operators 10 hours to complete.

Our experienced profiling crew effectively worked with traffic management and the various traffic diversions required to minimise road user disruption throughout the works.

Dowsing Group expertly completed the road profiling works with no delays to the following asphalt schedule and promptly assisted with the emergency road incident requirements at very short notice.
