How to Write a Construction Dust Control Plan: A Template

Every construction site generates dust, and much of it carries respirable crystalline silica, the contaminant behind silicosis and the driver of the most significant work health and safety reform in a generation. Since September 2024, Chapter 8A of the model WHS Regulations has required specific controls for crystalline silica substances, and the transition from the Workplace Exposure Standard to a Workplace Exposure Limit in December 2026 turns the 0.05 mg/m3 airborne silica limit from a guideline into an enforceable ceiling. That national standard is set by Safe Work Australia at 0.05 mg/m3 over an eight-hour shift, while WorkSafe Victoria recommends a stricter target of 0.02 mg/m3 over the same period. A construction dust control plan is the document that shows how a site will identify, assess, control, monitor and record its dust management, and it is expected under planning consent conditions, principal contractor duties and the CEMP. A complete plan covers ten sections, from purpose and receptor mapping through dust source identification, control measures by activity, a Trigger Action Response Plan, monitoring, record-keeping and review. The Safe Work Australia Model Code of Practice is explicit that basic water spraying is not sufficient for high-risk silica work, so engineering controls are required. GRT products map onto that framework: GRT: Haul-Loc dosed through SMART Dosing Units extends road suppression from minutes to hours per pass and logs each application with timestamp, volume and concentration; GRT: Activate added to spray or wet-cutting water captures the fine respirable fraction up to 12x more effectively for demolition and concrete work; GRT: Enviro-Binder and GRT: Soil-Loc bind exposed and cleared surfaces, and GRT7000 stabilises permanent access roads. The records are the evidence: when an inspector asks whether the controls were active during a dust event, SMART Dosing telemetry gives a timestamped answer.

Dust Suppression Equipment Guide: Water Carts, Cannons & Dosing

The dust suppression market runs from a garden hose to a fully automated fog cannon, and the marketing rarely explains which situation each is actually suited to. Different dust sources need different delivery methods: haul roads need the mobile coverage of a water truck, crushers and transfer points need fixed-position spray bars or misting rings, stockpiles need the long-range throw of a fog cannon, and a processing plant needs chemical dosing into its existing spray network. But every one of these is, in the end, a device for delivering water, and plain water captures coarse dust while largely missing the fine respirable fraction (PM10 and PM2.5) that matters most for health and compliance, because the droplets are too large to interact efficiently with particles smaller than 10 microns. This limit applies to every hardware type. Chemical activation changes that. GRT: Activate lowers surface tension and adds ionic charge so each droplet captures the fine fraction far more effectively, up to 12x, from the same nozzles at the same pressure. Dosed inline, it upgrades every fixed spray and fog cannon on site from a single point, with no new pipework or pumps. On haul roads, GRT: Haul-Loc dosed through SMART Dosing Units at the fill point extends each pass from minutes to hours, using the trucks you already own, and logs every dosing event with timestamp, volume and concentration for auditable reporting. The most cost-effective upgrade is usually not new hardware. It is in the water.

Watershed Management for Mine & Civil Sites

Erosion control is usually treated as a site-level problem: the slope erodes, the basin captures the sediment, the water is discharged and compliance is met at the boundary. But sediment does not respect site boundaries. Turbid discharge that is compliant at the release point can become a water quality problem far downstream, where fine clay smothers habitat and sediment-borne nutrients feed algal blooms, and the combined load from several sites in one catchment can exceed what the waterway can carry long before any single site breaches its own limits.

Australian law increasingly reflects this: Queensland's Environmental Protection Act 1994 makes it an offence to deposit prescribed water contaminants into waterways, the NSW Protection of the Environment Operations Act 1997 makes it an offence to pollute waters, and the Commonwealth EPBC Act 1999 can apply where a downstream matter of national environmental significance is affected. Cumulative impact assessment is now standard for major project approvals. The most effective control point is the source, because sediment prevented at the exposed surface never has to be transported, captured, treated or managed downstream. GRT: Enviro-Binder and GRT: Soil-Loc bind exposed surfaces, GRT7000 stabilises unsealed roads to cut a sediment source that is often overlooked, GRT: Floc Blocs treat drainage passively during every rainfall event without power or operators, and GRT: CC and GRT: Liquid-Floc polish basin water before controlled release, with SMART Dosing Units documenting each application for reporting.

The True Cost of Water Trucks for Dust Suppression

Most operations can quote the hire rate or the diesel bill for a water truck. Fewer can quote the total, because the real cost of water-based dust suppression is the full stack it generates across the operation. Beyond fuel, operators, tyres, maintenance and the water itself, water-only suppression drives hidden costs: road degradation from over-watering, extra grader hours repairing softened surfaces, production losses when dust reduces haul road visibility, accelerated haul truck tyre wear on corrugated roads, and the traffic interaction risk of every water truck sharing the road with the production fleet. Water sprayed on a haul road evaporates quickly, so suppression is intermittent and the passes keep repeating.

Polymer-enhanced suppression changes the chemistry rather than adding trucks. GRT: Haul-Loc, dosed into the existing water trucks through SMART Dosing Units at the fill point, binds the wearing course so each pass holds dust for much longer, which lets an operation reduce watering passes and redeploy or off-hire surplus trucks. There is no new fleet and no manual mixing, and every fill event is recorded with timestamp, volume and concentration for auditable reporting. Unlike chloride salts, which depend on humidity, or lignosulfonate, which re-dissolves in rain, polymer suppression works through structural particle binding across arid, humid and temperate climates.

Dam Sealing & Repair for Mining and Farm Dams

A leaking dam loses more than water. For a mine it is process water that must be replaced from bore fields or purchased supply, and for a farmer it is the water that stands between a productive season and emergency carting. Australia has an estimated two million farm dams, alongside the thousands of water storage, sediment and tailings dams the mining industry operates, and many leak for the same well-understood reasons: inadequate clay or compaction, dispersive soils, wet and dry cracking, tree roots and animal burrows, or foundation seepage.

The conventional repair of drain, excavate, recompact and refill is slow and often fails, because it commonly reuses the same material that leaked and leaves a weak compaction interface. GRT: DamSealer works differently. Applied to the water surface, its polymer particles are drawn by the currents the leaks themselves create, accumulate in the cracks and channels, and are held in place by the dam's own hydrostatic pressure to build a progressive, long-term seal. The dam stays in service, no draining or earthmoving is needed, and standard applications require no specialist equipment. Alongside DamSealer, GRT9000 treats dispersive soils, GRT: Enviro-Binder protects embankment slopes from erosion, GRT: CC, Liquid-Floc and Floc Blocs treat water before controlled discharge, and GRT: Soil-Loc protects dam surrounds.

Great Barrier Reef Erosion Control for Mine and Civil Sites

The Reef 2050 Water Quality Improvement Plan targets a 25% reduction in anthropogenic fine sediment loads entering the Great Barrier Reef by 2025, yet the 2021 to 2022 Reef Report Card recorded only a 0.8% reduction in fine sediment across the catchment over the two-year reporting period (Reef Water Quality Report Card 2021 and 2022, Queensland Government). Fine sediment from cleared surfaces, haul roads and stockpiles moves through Queensland's 35 river catchments and into Reef waters, and a single high-intensity storm can mobilise more sediment from an unprotected surface than a full year of moderate rainfall.

Individual mine, quarry and construction operations can lower their own contribution with engineering-level erosion control. GRT: Enviro-Binder binds exposed surfaces to reduce sediment in runoff and works on steep batter and waste dump slopes, while supporting the revegetation that becomes the permanent erosion control. Paired with GRT: CC, GRT: Liquid-Floc and GRT: Floc Blocs for sediment basin treatment, GRT7000 and GRT: Haul-Loc for road sediment and dust, and SMART Dosing Units for application records, it gives operations a layered defence that stands up under the most intense rainfall scenarios.

Dust and Erosion Control for Solar and Wind Farm Construction

Before a single panel is mounted or a turbine goes up, a renewable energy project is a construction site, often one that clears and grades hundreds of hectares. There is a real irony here: a project built to reduce environmental impact can cause serious dust and sediment problems during construction if erosion controls aren't in place. For an industry that markets itself on its environmental credentials, that is a reputational risk as much as a regulatory one.

The two persistent pressure points are the access roads and the exposed ground between clearing and installation. GRT7000 stabilises access roads using the material already on site, giving a dust-free, all-weather surface for the life of the project, while GRT: Enviro-Binder protects cleared surfaces and cable trench backfill, tested by Landloch to deliver near-zero sediment on gradients up to 30% under storms up to a 50-year event. Controlling dust at the source also keeps it off the panels, where it would otherwise cut output.

Hydromulching vs Spray-On Polymer Erosion Control: Which Method Fits Your Project?

When you need to protect a disturbed surface from erosion and get vegetation established, two methods dominate: hydromulching, which sprays a slurry of mulch, seed and binder through a specialist machine, and spray-on polymer, which binds the soil surface using equipment the site already owns. Both work. They are not interchangeable.

Hydromulching keeps its edge on severely degraded soils, where delivering seed, fertiliser and mulch in one pass genuinely helps, and where a rehabilitation plan specifies it. But for progressive treatment during operations, remote sites, and tight budgets, GRT: Enviro-Binder often makes more sense: it is applied by the site's own water truck within 24 hours of a surface being exposed, with no contractor to mobilise. It has also been independently tested by Landloch under simulated 2, 10 and 50-year storm events, delivering near-zero sediment on gradients up to 30%. Choose the method that matches the project, not the one you used last time.

Quarry Dust Control: Crushing, Stockpiles and Roads

A quarry generates dust at three distinct points: the crushing and screening circuit, the stockpiles, and the haul and access roads. Each one throws off a different type of dust, and treating only the most visible source leaves the other two feeding the boundary monitor. Water helps for minutes, then evaporates and the surface goes straight back to generating dust.

GRT treats each source at its origin rather than chasing the plume. At the crusher and screens, GRT: Activate is dosed into existing spray water to make each litre up to 12x more effective at capturing the fine respirable fraction that plain water misses. On stockpiles, GRT's polymer veneering binds the surface against the wind erosion that, according to WeatherSolve Structures, can cost 3 to 15% of product to dust loss. And on haul and access roads, GRT: Haul-Loc extends dust suppression from minutes to hours per pass. One approach across the whole site rather than three disconnected fixes.

Dust Suppression in Melbourne and Victoria: Site Requirements and Solutions

Victoria's dust rules are among the most demanding in Australia. WorkSafe Victoria recommends keeping respirable crystalline silica exposure below 0.02 mg/m3 over an 8-hour shift, stricter than the national Workplace Exposure Standard of 0.05 mg/m3, and the EPA's general environmental duty requires every site to minimise dust risk so far as reasonably practicable. At the same time, the state's infrastructure boom is generating disturbed ground within metres of homes, schools and hospitals across Melbourne.

That combination raises the bar: plain water rarely satisfies "reasonably practicable" when proven polymer alternatives exist. GRT's polymer range meets both the WorkSafe and EPA sides of the equation, with GRT: Haul-Loc for construction and access roads, GRT7000 for stabilising the reactive clay across Melbourne's growth corridors, and GRT: Activate for the concrete cutting and demolition work where silica exposure is the real risk.
