Silica Dust Compliance NSW: Pumped Screed Solution

From 1 October 2025, the NSW Silica Worker Register requires all workers exposed to silica dust to be registered within 28 days. For builders still mixing levelling compound bags on site, this is a wake-up call. Pumped screed eliminates silica dust at the source.

NSW Chapter 8A and the Silica Worker Register

NSW introduced Chapter 8A to the Work Health and Safety Regulation on 1 September 2024. It imposes strict controls on crystalline silica exposure, including workplace exposure standards, health monitoring, and now a mandatory worker register for silica-exposed trades.

Cutting, grinding, and mixing bags of cementitious products on a concrete slab generates respirable crystalline silica. Even with PPE, dust spreads across the site, affecting every trade present.

How Pumped Screed Eliminates Silica Dust

Self levelling screed delivered by a road-based pump truck removes the dust generation entirely. The product is mixed in a closed drum on the truck, delivered through a hose, and pumped directly onto the slab. No bags are cut, tipped, or mixed on your site.

The result is not just compliance. It is a cleaner site, safer workers, and no cleanup time before the next trade can start. Tilers, carpet layers, and joiners can begin work the same day the screed is poured.

What Builders Need to Do

If you are still specifying hand-mixed screed, you are exposing your site to silica dust and your business to compliance liability. Switching to a pumped system removes the hazard entirely and gives you a documented, Hychem-backed finish with a printed docket for every pour.

Documentation for Compliance

Every PowerPump pour comes with a printed batch docket showing exact product weights, mix ratios, and coverage. This documentation satisfies WHS officer and principal contractor requirements for hazardous substance records.
