We are a commercial asphalt contractor first, so a carpark job runs from ground preparation through to the final line marking under one contract. Retail centres, strata properties, aged care facilities, and industrial yards across the Central Coast have relied on our team for new builds and full resurfacing.
Commercial pavement design is driven by the expected traffic loading. A light vehicle carpark for a medical centre has different pavement requirements than a heavy vehicle yard for a logistics operator. We design and build to the loading, not a generic standard that may be over or under-specified for your site.
Strata and body corporate work requires communication with owners corporations and compliance with council approval processes. We have handled this paperwork many times over and can guide you through the process from first quote to final handover documentation. A carpark of any real size justifies the float, and we build them around Newcastle and Lake Macquarie, out at Maitland and down at Hornsby.
Pavement Design
Thickness and subgrade design based on expected traffic loading, from light vehicles to heavy trucks.
Line Marking
Compliant bay layouts, directional arrows, disabled bays and safety markings to AS/NZS 2890.
Wheel Stops and Bollards
Concrete wheel stops, bollards and kerbing installed as part of the same contract.
Drainage Works
Stormwater pits, grated channels and connection to existing drainage systems.
Strata Support
Experience with owners corporations and body corporate works. We handle the approvals.
Anatomy of a carpark that works
Seen from above, a good carpark is geometry before it is asphalt. These are the figures a compliant layout gets right, typical values for retail and commercial sites.
- Bay sizing 2.4–2.6m × 5.4m
AS/NZS 2890.1 works from a 2.4m by 5.4m bay, widened to around 2.6m where retail turnover means doors opening on both sides. Width is set by who parks there, not by how many bays the plan can squeeze in.
- Aisle width 6.2m two-way
90 degree bays need a 6.2m aisle for two-way flow, 5.8m one-way, so a driver swings into a bay in one movement. Undersized aisles mean shunting, clipped corners and scraped bumpers.
- Accessible compliance 2.4m + 2.4m shared
AS/NZS 2890.6 requires a 2.4m bay beside a 2.4m shared area on the same level, hatch-marked, kept clear and signed with the symbol. Certifiers check this bay before anything else.
- Drainage and falls
Falls are controlled by survey levels so water sheds across the pavement to pits instead of ponding in bays. Accessible areas cap the gradient at 1:33 on outdoor asphalt, so levels are designed, never eyeballed.
A carpark works or fails on paper. Right bay geometry and right falls give you twenty quiet years; wrong ones give you ponding, scraped doors and complaints from the day it opens.

The Process
Every job follows the same standard. No steps skipped, no quality shortcuts.
Site Survey and Pavement Design
Traffic loading assessment, existing pavement condition check and formal pavement thickness design.
Sub-base and Base Course
Subgrade preparation and granular base course construction to the specified depth.
Asphalt Pavement and Drainage
Wearing course asphalt placement with all drainage structures installed concurrently.
Line Marking and Handover
AS/NZS 2890 compliant line marking, signage and full handover documentation provided.
Frequently Asked
Questions specific to Commercial Carparks on the Central Coast.
Ask Us Anything →Getting other quotes too? Smart. Take our questions sheet (PDF).
Can you resurface an existing carpark without full reconstruction?
Often yes. We assess the existing pavement structure. If the base is still sound, a mill and overlay or a direct overlay can restore the surface at significantly lower cost than full reconstruction.
Do you provide disabled bay markings to the required standard?
Yes. All disabled bay markings comply with AS/NZS 2890.6 and the relevant Australian Standards. We include international symbols, linework, and where specified, signage.
How do you handle strata approval processes?
We prepare scopes and quote documents in a format that supports strata approval meetings. We can also attend or provide written support for body corporate approvals where required.
- Pavement designed for light vehicles, then loaded by heavy trucks
- Bay layout drawn without checking compliant aisle widths
- Drainage shaping done by eye, not controlled by survey levels
- Line marking subcontracted with no coordination on the finished grade
- No AS/NZS 2890 documentation for strata or council handover
- Contractor unavailable when bay markings fade after six months
Resurfacing needed in year four. The strata committee votes it down.
Glenn and his team were terrific. Such a difficult job made to look easy.
