Line Marking Oxley QLD

Yes. Oxley Seventeen Mile Rocks Road industrial and Oxley Road logistics facilities are part of our south-western Brisbane schedule. Concrete age and aggregate type assessed before etch parameters specified — older concrete with coarser aggregate may need higher acid concentration for uniform surface profile. We've completed 5,000+ projects nationally since 2009 and carry $20M public liability. Fixed pricing, TMR approved.

Yes — higher acid concentration on modern concrete that responds well to standard protocol can produce over-etching, creating a profile that's too deep and removing too much cement from the surface. This weakens the surface layer and can actually reduce pull-off values. Using different protocols for each section and testing after each protocol is the correct approach, not blanket application of the stronger protocol to the full floor.

Sometimes — older concrete has more surface weathering, visible aggregate honeycombing repairs, and different colour/texture from modern mixes. But visual identification is unreliable. Construction records, lease documents with building details, or council property records are more reliable sources of construction date information. We request construction records where available and use pull-off testing and acid etch response as the practical diagnostic.

TMR Queensland approved since 2009. We meet contractor qualification, insurance, and technical standards for state and council road networks. We carry $20M public liability and $10M professional indemnity — certificates available on request. All road marking in Oxley is completed to AS 1742.3 with retroreflective thermoplastic to AS/NZS 1906.3. You receive as-built photos, a compliance statement, and material certification on every job. We also cover Sumner, Darra, Wacol on the same schedule.
