Concrete Topping Slabs Can Be Delaminated From the Base — Tap the Floor Before You Prime
A Sunshine West automotive parts warehouse had a new concrete topping slab applied over the original worn concrete floor. Nobody mentioned this to us — the floor looked like one continuous concrete surface. We applied primer. In three areas, full panels of the concrete topping slab lifted as the primer adhesion during application exceeded the bond strength between the topping and the base concrete. The delaminated sections were approximately 600mm x 800mm each.
This is a known risk with concrete topping slabs — if the topping isn't adequately bonded to the base, any adhesive coating applied to the surface can pull it up. The delaminated sections had been failed bonds waiting to fail; our primer simply provided the adhesive force that triggered the failure.
The hollow-sound tap test identifies delaminated topping sections before primer is applied. Walk the floor and tap with a steel rod or hammer at regular intervals — a delaminated section produces a hollow, drum-like sound versus the solid thud of a well-bonded topping. Any hollow section should be fully removed and repaired before marking. We now tap-test every Sunshine West and Brimbank industrial floor that has visible evidence of a topping slab — different concrete colour, different aggregate, saw-cut joints that don't continue into the base.
Sunshine West is the Ballarat Road manufacturing and automotive corridor in Brimbank City. VicRoads approved. Concrete topping delamination tap test is standard on every Sunshine West floor with evidence of a topping slab.

Frequently Asked Questions
Yes. Sunshine West Ballarat Road automotive and manufacturing facilities are part of our Brimbank schedule. Concrete topping delamination tap test on every floor with evidence of a topping slab — hollow sections repaired before primer application. We've completed 5,000+ projects nationally since 2009 and carry $20M public liability insurance. Every Sunshine West quote includes a site assessment, surface condition report, and fixed pricing. No estimates that change at invoicing. For WorkSafe Victoria 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. VicRoads approved for any road or carpark marking that requires local council or state road authority sign-off.
A concrete topping slab is a thin layer of concrete (typically 25-75mm) applied over an existing worn or damaged concrete floor to create a fresh surface. If the topping-to-base bond is inadequate — from insufficient surface preparation before topping was applied — the topping can delaminate. Any adhesive coating applied to the surface can pull the delaminated section up rather than bonding to it.
Walk the floor systematically and tap with a steel hammer or rod at 300-500mm intervals across the surface. A well-bonded topping produces a solid thud. A delaminated section produces a distinctly hollow, drum-like resonance. Mark all hollow-sounding sections with chalk and exclude them from marking until repaired. Surface preparation is assessed before every Sunshine West warehouse job, not assumed. That means checking moisture content, surface pH, contamination, and existing coating compatibility before a product is specified. We've completed 5,000+ warehouse and industrial floor marking jobs since 2009, and we carry $20M public liability insurance. Completion documentation includes product data sheets, application records, and compliance certification.
Not reliably. Injecting epoxy grout under delaminated sections can re-bond small areas, but larger delaminations need full removal and repair. We recommend getting a structural engineer's assessment for large delaminated areas before deciding on repair method. Line Marking Australia has been completing marking across Sunshine West and surrounds since 2009, with 5,000+ projects nationally. We carry $20M public liability and $10M professional indemnity insurance, VicRoads approved.
