Angular Silica Aggregate in a Local Seal Coat Tears Thermoplastic Application at the Machine Shoe
A Geraldton port services facility hardstand had been recently seal-coated with a bituminous seal using aggregate from a local Mid West quarry. Regional quarries often supply angular, sharp-profile aggregate rather than the rounded or semi-rounded aggregate used in Perth metropolitan seal coats. The angular silica pieces sat proud of the bituminous binder at approximately 8-10mm height.
Our standard thermoplastic machine shoe rides approximately 5-6mm above the surface to control film thickness. The 8-10mm proud aggregate profile caught the machine shoe edge repeatedly, causing the shoe to skip and drag over the aggregate peaks. The result was irregular thermoplastic thickness — thin in the aggregate peak zones, thick in the valleys between aggregates — and tearing of the thermoplastic film where the shoe dragged.
Angular proud aggregate seal coat surfaces require either a hand-trowel application or a higher-clearance shoe setting to accommodate the profile. Hand trowel application forces the thermoplastic into the valleys and around the aggregate peaks without the shoe contact problem. For any Geraldton or Mid West regional facility with local-aggregate seal coats, we assess the aggregate profile and decide the application method before the session.
Geraldton is the Mid West WA hub — the Port of Geraldton serving mining, fishing, and agricultural exports, Marine Terrace commercial, and the industrial businesses supporting the region's mining and fishing industries. MRWA approved.

Aggregate seal coat profile assessed before application method selected on any seal-coated surface. We've completed 5,000+ projects nationally since 2009 and carry $20M public liability insurance. Every Geraldton quote includes a site assessment, surface condition report, and fixed pricing. No estimates that change at invoicing. For WorkSafe WA improvement notices we can typically assess within 24 hours and deploy within 48-72 hours. Completion comes with photo documentation, a compliance statement, and material specifications. MRWA approved for any road or carpark marking that requires local council or state road authority sign-off.
Rounded aggregate sits with its smooth curved surface upward, providing a less extreme profile change between aggregate peaks and valleys. Angular aggregate has sharp edges and flat faces that can sit at steep angles in the binder, creating more extreme peak-to-valley height changes and sharper edges that catch the thermoplastic machine shoe. Line Marking Australia has been completing marking across Geraldton and surrounds since 2009, with 5,000+ projects nationally. We carry $20M public liability and $10M professional indemnity insurance, MRWA approved.

Yes — hand trowel is approximately 40-50% slower per linear metre than machine application for standard lines. For short marking runs in isolated problem zones, the time difference is manageable. For a full large carpark of seal-coated surface, we'd discuss whether a different product (cold-applied paint) might be more practical than trowel-applied thermoplastic for the full area.

Light sanding or grinding to reduce the most extreme aggregate peaks is possible and can improve machine application performance. The trade-off is reducing the slip resistance of the seal coat — which is typically the reason for the angular aggregate selection. We discuss the option with the facility manager before grinding any seal coat surface.
