Colonnades Shopping Centre Has a Multi-Level Carpark With Different Surface Ages on Each Level — Assess Each Individually
Colonnades Shopping Centre in Noarlunga has a multi-level carpark that's been extended and modified over its operational life. Different levels were constructed at different times, meaning the deck surface ages, coatings, and condition vary significantly across the structure. A single preparation protocol applied to the full carpark will be wrong for most levels.
We assessed level by level during our pre-marking site visit. Level 1 ground: original concrete from the 1970s, fully carbonated, needed mechanical grinding. Level 2: a 1990s waterproofing membrane, partially delaminating in the traffic areas. Level 3 roof: recent polyurethane re-membrane from 2018, compatible primer specified from the membrane supplier.
Three different preparation and primer approaches across three levels. The as-built documentation identified which product and method was used on each level. The shopping centre's facilities manager specifically requested this per-level record for their preventive maintenance program.
Noarlunga is Onkaparinga's major commercial hub — Colonnades Shopping Centre, Noarlunga Health Village, and the southern Adelaide commercial businesses on the Lonsdale Road corridor. DPTI approved.

Frequently Asked Questions
Yes. Noarlunga Colonnades Shopping Centre, Noarlunga Health Village, and Onkaparinga commercial carparks are part of our Adelaide southern schedule. We conduct per-level surface assessment on multi-level carparks before specifying preparation and primer — surface ages and conditions vary significantly in older structures. Fixed pricing, DPTI approved. We've completed 5,000+ projects nationally since 2009 and carry $20M public liability insurance. Every Noarlunga quote includes a site assessment, surface condition report, and fixed pricing — no estimates that change at invoicing. For SafeWork SA improvement notices we can typically assess within 24 hours and deploy within 48-72 hours. Completion includes photo documentation, compliance statement, and material specifications. DPTI approved for any road or carpark marking requiring local council or state road authority sign-off.
Carbonation is the chemical reaction between atmospheric CO2 and calcium hydroxide in concrete over decades. The carbonated surface layer resists standard acid etching because calcium carbonate (the product of carbonation) is more acid-resistant than the original concrete chemistry. For 1970s-era concrete like Level 1 at Colonnades, mechanical diamond grinding to CSP-2 is the reliable preparation method. It physically removes the carbonated surface layer and exposes fresh reactive concrete regardless of the carbonation depth.
Partially delaminated membrane presents two options: remove the delaminated sections entirely and prepare the exposed concrete, or stabilise the membrane edges and mark around the problem zones. For large-area delamination (more than 10% of the deck), removal is usually better. For isolated delamination in traffic zones, mechanical removal of the failed sections and compatible concrete preparation for the exposed areas, with compatible membrane-to-concrete transition marking, is the approach.
Yes. Based on the per-level as-built documentation, we can provide a maintenance schedule recommendation showing expected remark intervals for each level based on the product applied, traffic loading, and surface condition at time of marking. Roof levels with full UV exposure typically need remark every 4-5 years; sheltered lower levels can go 6-8 years. This schedule helps the facilities team budget for marking across a multi-level structure with different maintenance cycles.
DPTI South Australia approved since 2009. Approval means we meet contractor qualification, insurance, and technical standards to work on state roads and local government road networks. We carry $20M public liability and $10M professional indemnity — your risk manager can request certificates in writing. All road marking in Noarlunga is done to AS 1742.3 traffic control standards with retroreflective thermoplastic to AS/NZS 1906.3. Traffic management plans provided before every job.
