Dust Suppression


Innovative Dust Suppression and Dust Control Solutions.

Global Road Technology (GRT) is a world leader in innovative dust suppression technology that helps overcome the global challenge caused by dust in various industries and sectors such as mining, quarries, civil projects, and more.

Australia Made and ISO Certified dust suppression solutions

GRT has developed its dust suppression systems and technologies so that they are simple to use, highly efficient, and improve cost-effectiveness over time. These water additive products act as dust suppressants to enhance the efficiency of water to capture the dust particles for a longer duration thereby reducing water usage and increasing dust suppression.The products or solutions can deliver these benefits using existing or readily available equipment such as existing spray systems and water lines, misting systems, water trucks, cannons, spray nozzles and overhead spray bar systems.

GRT’s dust suppression technologies fall under six main product groups:

1. GRT: Haul-Loc: Ultra-concentrate that uses GRT’s LCP technologies to improve the efficiency and effectiveness of water cart operations by up to 500%. Save water, eliminate dust, and improve safety on your haul roads.

2. GRT: ACTIVATE UG – Super activated, dust suppression for underground mining. This product is injected into water supply lines and sprayed through existing spray systems for the longwall, continuous miners, conveyors and designed to target harmful airborne coal and silica dusts.

3. GRT: Drill & Blast Applications: GRT: 12X & GRT: DC Binder. These products help to super-activate the water used in drilling and blasting. The chemical interactions enable binding the surface of fine drill cutting piles. This prevents them from producing airborne dust.

4. GRT Wet-Loc: Non-drying and non-setting, synthetic fluid designed to adsorb into soil particles preventing them from becoming airborne. GRT Wet-Loc is a long-lasting, totally waterless application that is ideally suited to underground mining roads, areas of heavy damaging traffic such as tracked machinery routes, and race tracks (speedways and even horse and camel tracks).

5. GRT: ACTIVATE: Cutting edge dust suppression technology that makes water work better, harder, and more efficiently. Injected through existing spray systems, trucks or stabilizers, key applications are for quarrying crushers and conveyors and for road construction.

6. GRT: Broadscale Applications: GRT: Soil-Loc, GRT: Ore-Loc, and GRT: Rubble-Loc. Specific formulations for farming, resources, ore stockpiles and transport, and demolition and disaster recovery sites. These products show that a little of the right technology goes a long way!


Conventional dust suppression methods waste water, contaminate runoff, contain hazardous chemicals, reduce road stability, impact driver safety and increase costs.

GRT’s environmentally and safety friendly products result in excellent dust prevention and higher quality, more durable roads. Customer feedback and independent scientific analysis found that these dust suppression products suppress greater than 95% of dust particles and delivered up to 75% cost savings compared to conventional water-only options.

GRT’s technology offers a total site-wide dust suppression solution and solves a range of dust problems on all types of roads, from major highways and freeways to haulage, industrial and rural roads, tarmacs, hardstand areas and water repellent pavements. It can be easily applied to clay, silt, sand and gravel materials, immediately creating safer, more sustainable and cost-effective infrastructure.

Are environmental regulations, health and safety concerns or potential profit loss a concern right now?


Compared to conventional processes, GRT’s dust suppression products offer a cost effective solution. They have a set of distinct advantages and lucrative benefits, including easy application and long life protection across extreme climatic conditions.

Our products also offer the toughness and flexibility to be applied across a diverse spectrum of industries, improving safety and eliminating dust complaints from staff and surrounding landholders.

Apart from the longer-term maintenance efficiencies, savings can also be achieved from the significant reduction of windborne material losses. Plus, as a non-toxic product with a low carbon footprint, it offers further environmental protection by reducing the damage caused by fugitive dust.

TOTAL DUST MITIGATION STRATEGY FROM PIT TO PORT

IECA Member Logo

Dust suppression is the corrective best practice of dealing with fugitive dust particles that have been dislodged from their source. It limits the extent to which dust particles travel in the air.

A dust suppression unit produces droplets and fine mists and fogs of dust suppressant solutions that bind and attach to dust particles. The nozzles nebulize the dust suppression solution to smaller particles to match the size of dust particles.

Different dust suppressants have different mechanisms of action. For example, surface active agents lower the surface energy of water which enables surface charge similarities with dust particles and subsequent binding of the dust particles.

Dust suppression is important to reduce the respiratory health risks associated with both short- and long-term dust exposure. Once inhaled, the respirable dust particles lodge into the deepest parts of the lungs which often leads to fatal diseases such as silicosis and lung cancer.

“Recognised Standard 20” for dust control in surface mines

The purpose of this recognised standard is to state ways for the site senior executive (SSE) to meet their safety and health obligations, and develop their mine’s safety and health management system (SHMS) for the control of dust (respirable and inhalable) at a surface coal mine.
