Coastal Concrete Absorbs Chloride Ions From Saline Spray Over Years — These Migrate Under Coatings and Blister

A Henderson marine facility hardstand adjacent to Cockburn Sound had absorbed years of saline spray from the water. Chloride ions from salt spray penetrate concrete and concentrate within the surface layer. Unlike salt residue from cleaning products — which sits on the surface and can be rinsed off — embedded chloride ions are within the concrete matrix and cannot be removed by surface washing alone.

We primed and marked the hardstand. Initially it looked correct. Over eight months of tidal and weather cycling, osmotic blistering appeared across the marked surface — the cyclical wetting and drying of the concrete caused the embedded chloride ions to repeatedly dissolve and concentrate at the concrete-to-primer interface, drawing moisture through the primer film by osmosis.

For coastal concrete exposed to saline spray, the correct pre-treatment is a chloride extraction process — high-pressure fresh water flooding and multiple rinse cycles over several days to flush chloride ions toward the surface and out of the concrete, followed by moisture content testing and a chloride content test on the rinse water to confirm extraction. Some marine primer systems are formulated specifically for chloride-contaminated substrates and don't require full extraction.

Henderson is Perth's heavy marine and defence industrial precinct — the Australian Marine Complex, ASC West, and the defence and shipbuilding businesses on Cockburn Sound. MRWA approved. Marine saline chloride assessment is standard on every Henderson coastal concrete hardstand before marking.

Frequently Asked Questions

Yes. Henderson Australian Marine Complex and defence precinct hardstands are part of our Perth southern schedule. Marine saline chloride assessment on every coastal concrete hardstand adjacent to Cockburn Sound. We've completed 5,000+ projects nationally since 2009 and carry $20M public liability insurance. Every Henderson 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.

Chloride ions from saline spray penetrate into the concrete through absorption over many years — they're distributed through the concrete pore structure to a depth of 10-30mm. Surface pressure washing wets the surface and dissolves only the ions at the immediate surface. The ions deeper in the concrete matrix remain in place and continue to migrate toward the surface during subsequent wet-dry cycles.

Marine-grade epoxy primers are formulated with higher chloride tolerance — they use binder systems that maintain adhesion in chloride-contaminated environments and resist osmotic blistering. Standard amine-cured primers are more susceptible to osmotic failure from chloride cycling. Marine-grade products are more expensive but significantly more durable in coastal industrial environments like Henderson. Line Marking Australia has been working to AS/NZS standards since 2009 and we carry $20M public liability insurance. Every job in Henderson comes with a compliance statement specifying which standards apply, the materials used (including product data sheets), and photographic documentation of the completed work. This gives your facility manager, safety officer, or auditor a complete record without having to chase it.

A small concrete core or surface scraping can be submitted to a materials laboratory for chloride content testing. NATA-accredited labs in Perth perform this test. The result gives a chloride concentration in kg/m3 — thresholds for applying marine-grade primer versus extraction treatment are typically set at 0.4 kg/m3 (primer) and above 1.0 kg/m3 (extraction recommended). Line Marking Australia has been completing marking across Henderson and surrounds since 2009, with 5,000+ projects nationally. We carry $20M public liability and $10M professional indemnity insurance, MRWA approved.
