Works with dust so you don’t have to!

GRT Haul-Loc is a specially formulated liquid polymer added to watering trucks used to reduce water required for continuous dust suppression by at least 65% and extend the dust suppressing effects four to five times longer than water alone.

We’ve Got Dust Covered

Left untreated, dust from unsealed haul roads, hardstands, cleared sites, and large soil/mineral stockpiles can have a considerable impact on sta, the environment and the quality of life for local communities.

GRT: Haul-Loc minimises this impact by locking down dust, as well as providing budget savings in the reduction of water truck movements – also reducing the potential for incidents by reducing traffic volumes. The use of GRT: Haul-Loc also eliminated the impact of overwatering for dust control leading to haul roads with improved surface integrity.

GRT will work with you to devise a full dust mitigations strategy to meet the challenges facing your project or business operation. We can also provide engineering input to design, layout, and maintenance of your site roads as well as opportunities to optimise available materials for construction.

Key Benefits:

Increase the effective total area able to be treated per truck by at least 250%.

Annual cost savings (based on Cat 777 water trucks) of $1.2 million per truck.

Reduction in water consumption by at least 65%

Avoid the impact of slowing down or stopping production due to poor visibility on your haul roads.

Fully Automated Dosing Units

Designed and manufactured in Australia, GRT’s dosing units range from simple hand-operated pumps to our fully automated dosing units used by some of the world’s largest mining and quarrying companies. GRT’s dosing units inject GRT: Haul-Loc into the flow stream of the water at your standpipe or hydrant fill points at our recommended dosage rates, calibrated to the rate of flow in the water supply pipe.

  • Solar-powered, generator or mains power compatible
  • Manual, remote control, or automated start
  • Permanently fixed, mobile skids/bunds, or even truck-mounted units available
  • Dual-purposed to dose our mining products GRT: Haul Loc and GRT: Activate


of organisations have improved their efficiency by introducing IoT & data monitoring technology

SMART Dosing Units Model 3

The system is almost exclusively a stand-alone solar-powered unit. Primary and secondary positive displacement dosing pumps are driven by a variable speed drive (VSD).

The highest quality, durable pumps, motors, and fittings have been incorporated to withstand the harshest onsite conditions.

The dose is calibrated to the flow in the standpipe or water feed and injected via an injection port. The flow in the pipe triggers the flow switch so no human input is required to start the unit – making it perfect for manned operations and completely integrate into current or future autonomous mining systems.
