Dust Suppression for Civil
Construction & Tunnelling Sites

Fixed high-pressure misting for boundary hoarding, haul roads and tunnel headings — designed to control respirable crystalline silica and PM10, satisfy the SWMS and meet SafeWork NSW obligations. NSW-based, projects nationwide.

✓ Respirable Silica / RCS ✓ PM10 / PM2.5 Standards ✓ SafeWork NSW ✓ SWMS Documentation Available
Trusted by leading civil contractors and infrastructure projects across Australia
The Challenge

On a Civil Site, Dust Is a
Safety and Compliance Liability.

Earthworks, demolition, shotcreting and tunnel boring generate respirable crystalline silica and PM10 that put workers and the programme at risk. SafeWork NSW exposure standards, principal contractor obligations and the project's SWMS all require documented dust controls before work starts.

youmist installs fixed high-pressure misting along hoarding, haul roads and tunnel headings — suppressing airborne particulates at the source of generation, automated to respond to conditions and integrated into the site's ventilation and safety management plan.

SWMS Requirement

Your principal contractor needs dust suppression in the Safe Work Method Statement before work can start. We move fast and document everything.

Respirable Silica / RCS

Cutting, grinding and tunnelling release crystalline silica. Suppression at the source helps keep exposure within SafeWork NSW standards.

Boundary or Neighbour Complaints

Dust leaving your site perimeter is a Protection of the Environment Operations Act issue. A fixed perimeter misting line along the hoarding solves it.

Tunnel & Heading Dust

Boring and shotcreting generate dust in confined headings. Fixed lines along the tunnel walls suppress it and integrate with the ventilation plan.

Sydney Metro Tunnelling Project
Fixed Suppression Along Tunnel Headings

Principal Contractor · Sydney Metropolitan

A principal contractor on a major Sydney metro tunnelling project required dust suppression along active tunnel headings to manage respirable dust and meet SafeWork NSW WHS obligations under the construction SWMS.

youmist installed fixed high-pressure misting lines along the tunnel walls, designed to suppress airborne particulates at the source of generation during boring and shotcreting operations. The system was specified collaboratively with the contractor's safety team and integrated into the tunnel ventilation management plan.


  • PM10 / PM2.5 ambient standards maintained
  • SafeWork NSW WHS Act obligations met
  • Integrated with tunnel ventilation management plan
  • SWMS dust suppression requirement satisfied

Compliance

Built Around the Standards
That Matter on Your Site.

Every youmist civil and tunnelling system is designed and documented against SafeWork NSW and EPA requirements, so that SWMS approval, principal contractor review and commissioning are straightforward from day one.

SafeWork NSW / WHS Act

Fixed suppression systems designed and documented to meet SafeWork NSW obligations for dust exposure in construction, tunnelling and demolition environments.

Respirable Crystalline Silica (RCS)

Suppression at the source of generation to help manage respirable crystalline silica exposure during cutting, grinding, boring and shotcreting.

PM10 / PM2.5 Ambient Air Quality Standards

System design targets NSW EPA ambient air quality standards for PM10 and PM2.5, including boundary monitoring integration where required.

SWMS Requirements

We provide full Safe Work Method Statement documentation for dust suppression operations, ready for principal contractor review and approval.
