Multi-Storey Carpark Line Marking
Since 2009, we've marked parking structures from basement levels to rooftop parking across shopping centres, office towers, hospitals, and apartment complexes. Level identification, directional arrows, colour-coded zones, and proper bay marking that works together as a complete wayfinding system. Your visitors find parking faster. Your traffic flows smoothly. And people can actually remember where they parked.

Multi-Storey Carparks Need More Than Just Bay Lines?
Quick answer: Line Marking Australia marks multi-storey and basement car parks with bays, colour-coded level zones, large level numbers at ramps, directional arrows and wayfinding text. We mark bays to AS/NZS 2890.1:2004, allow for the 2.2 m minimum headroom, prepare smooth or sealed concrete so paint bonds, and work in stages, usually at night.
A 2,400-bay Doncaster car park job
The centre management at a major shopping centre in Doncaster contacted us about their 2,400-bay multi-storey carpark. Five levels, multiple entry points, and a wayfinding system that wasn't working. Customers were getting lost, circling endlessly looking for spaces that existed on other levels, and security was spending hours helping people find their cars. The existing marking was a mess of faded lines, inconsistent arrows, and level numbers you couldn't read unless you were standing right next to them.
We proposed a complete overhaul: colour-coded zones on each level (purple on P1, blue on P2, green on P3, orange on P4, red on P5), large painted level numbers at every ramp transition, directional arrows with destination text, and fresh white bay marking throughout. It took four weeks of night shifts, 18,000 linear metres of marking, but the result was a carpark that actually worked. Customer complaints about parking dropped 60% in the first quarter after completion.
Why multi-storey car parks are different
Multi-storey carparks are fundamentally different from surface lots. The enclosed environment means lower light levels, especially in basement levels. Drivers can't see the whole carpark at once, so they're relying entirely on floor marking and signage to navigate.
Which standards apply to multi-storey car parks?
Bays and aisles follow AS/NZS 2890.1:2004, which also sets a minimum headroom of 2.2 m. Accessible bays follow AS/NZS 2890.6:2009, which needs 2.5 m headroom over the accessible bay and its shared area. Ramps, columns and pedestrian routes are where most incidents happen, so we mark crossings and keep-clear zones clearly. See our main carpark line marking page for bay sizes.
For larger buildings, see our wayfinding and bay numbering and directional arrows and stop bars on ramps and aisles.

Compliance Standards
Off-Street Parking Facility Design
AS/NZS 2890.1:2004, the primary standard for carpark design including multi-storey structures. Specifies bay dimensions, aisle widths, ramp gradients, and marking requirements. Multi-storey carparks have additional requirements for wayfinding and level identification not applicable to surface lots.
Accessible Parking in Structures
AS/NZS 2890.6:2009, multi-storey carparks require accessible parking provision on each level or in proximity to accessible routes to destinations. Accessible bays must be properly marked with the international symbol of access and meet dimensional requirements for wheelchair access.
Pavement Marking Retroreflectivity
AS/NZS 2009, specifies retroreflectivity requirements for pavement markings. In covered parking structures with reduced lighting, retroreflective marking significantly improves visibility. Our glass bead application at 400g per square metre meets these performance requirements.
Building Code Fire Safety
Building Code of Australia (NCC), multi-storey carparks have fire safety requirements including emergency vehicle access lanes, fire exit marking, and hydrant clearance zones. Floor marking must integrate with fire safety provisions and maintain clear evacuation routes at all times.
Workplace Traffic Management
Model WHS Regulations 2011, where multi-storey carparks serve commercial or industrial premises, they're classified as workplaces with traffic management obligations. Pedestrian routes, loading areas, and vehicle circulation must be clearly marked to protect workers and visitors from traffic incidents.
Road Marking Materials Performance
AS 4049.3 covers waterborne pavement marking paint, including adhesion to various substrates. Multi-storey carparks often have sealed or coated concrete that requires specific surface preparation and compatible paint systems for proper long-term adhesion.

Frequently Asked Questions
We test concrete moisture content before specifying materials. Standard waterborne paint requires moisture content below 4% to bond properly. If testing shows higher moisture (common in basements), we use moisture-tolerant epoxy systems that can handle damp substrates. We learned this lesson the expensive way on a South Yarra project years ago.
Absolutely. Large multi-storey carparks are typically done level by level over multiple nights. We coordinate with your operations team to determine which levels can be closed when. Often we'll do basement levels first, then work up through the structure. You maintain parking capacity throughout the project with reduced numbers on the level being marked each night.
In covered parking with lower light levels, we recommend 600mm to 800mm letter height for level identification painted on walls, columns, and floors. This is significantly larger than outdoor carparks because visibility is reduced. Level numbers need to be readable from inside a moving vehicle without the driver slowing down. Colour contrast matters too.
Yes, glass bead application is standard on all our multi-storey work. We use 400 grams per square metre, which is at the higher end of the specification range. In lower light conditions of covered parking, retroreflective marking makes a significant difference. The glass beads catch vehicle headlights and make lines much more visible than non-reflective paint.
Beyond standard bay lines, we incorporate colour-coded zones for each level, large level numbers on floors, columns and walls, directional arrows with destination text like EXIT and LIFTS, pedestrian walkway marking, and wayfinding routes to amenities. The specific elements depend on your carpark layout and what navigation problems you're trying to solve.
It depends on size and complexity. A small 3-level carpark with 200 bays might take 3 to 4 nights. A major shopping centre carpark with 2,000+ bays across 5 levels could take 3 to 4 weeks of night shifts. We provide detailed scheduling in our quote based on your specific carpark. Call Niel on 0417 460 236 to discuss your project timeline.
AS/NZS 2890.1:2004 sets a minimum headroom of 2.2 m in car parks, and AS/NZS 2890.6:2009 needs 2.5 m over accessible bays and their shared areas. Line Marking Australia can mark clearance heights at entries and ramps so drivers of taller vehicles know before they drive in.
