Commercial Asphalt Car Parks
Asphalt is a practical surfacing option for commercial parking areas because it creates a continuous, hard-wearing surface suitable for regular vehicle movements.
We construct and upgrade asphalt car parks for a variety of Christchurch properties, including:
- Retail premises
- Offices
- Warehouses
- Workshops
- Industrial properties
- Apartment developments
- Townhouse developments
- Body corporate properties
- Schools
- Community facilities
- Medical and professional premises
- Hospitality properties
Every site is different, so the pavement should be constructed around its expected use rather than taking a one-size-fits-all approach.
A small office car park used primarily by passenger vehicles has different requirements from an industrial parking and access area regularly carrying trucks and commercial vehicles.
New Asphalt Car Park Construction
Building a new asphalt car park involves considerably more than laying asphalt over the ground.
The strength and performance of the finished pavement depend heavily on what is underneath it.
Depending on the site, construction can involve:
Site Clearing
Existing vegetation, old pavement and unsuitable material are removed from the proposed parking area.
Excavation
The site is excavated to create sufficient depth for the required pavement structure.
Subgrade Preparation
The underlying ground is shaped and prepared before pavement materials are installed.
Basecourse Construction
Suitable aggregate is placed, graded and compacted to create a strong supporting pavement.
Drainage & Levels
The car park is graded so surface water can move toward appropriate drainage points.
Asphalt Surfacing
Asphalt is installed over the prepared pavement and compacted to create the finished surface.
Finishing & Tie-Ins
Connections with entrances, kerbs, concrete, drainage structures and surrounding surfaces are completed.
Asphalt Car Park Resurfacing
An existing asphalt car park does not necessarily need complete reconstruction simply because the surface has become old or worn.
Where the underlying pavement remains reasonably sound, asphalt resurfacing may provide a more economical way to extend its useful life.
Resurfacing generally involves preparing the existing pavement and installing a new asphalt layer over it.
Before resurfacing, we assess areas such as:
- Cracking
- Potholes
- Surface deterioration
- Failed patches
- Depressions
- Drainage
- Pavement edges
- Existing levels
- Manholes and service covers
- Connections to surrounding surfaces
Failed areas can be repaired before the new asphalt overlay is installed.
Planned resurfacing is a recognised pavement-maintenance approach in New Zealand; NZTA's current sealed-road resurfacing framework includes asphalt surfacing and milling followed by resurfacing among its resurfacing activities.
Asphalt Car Park Repairs
Car parks often deteriorate in isolated areas before the entire pavement reaches the end of its useful life.
Common problem areas include vehicle entrances, turning areas, loading zones and places where water regularly collects.
We provide repairs for:
- Potholes
- Broken asphalt
- Cracked areas
- Failed pavement
- Sunken sections
- Damaged edges
- Previous repair failures
- Utility trench reinstatement
- Localised pavement deterioration
Repairing deteriorated areas early can help prevent them from becoming larger pavement failures.
NZTA includes pavement dig-outs, patching and pothole repairs among routine sealed-pavement maintenance activities.
Asphalt Car Park Extensions
Need additional parking?
We can extend existing asphalt parking areas where the property has suitable available space.
A car park extension may involve clearing and excavating the new area before constructing a pavement that connects with the existing car park.
Careful consideration needs to be given to the transition between old and new surfaces, particularly around levels and drainage.
Extensions can be useful for:
- Growing businesses
- New tenants
- Commercial property upgrades
- Additional staff parking
- Visitor parking
- Apartment developments
- Warehouse expansions
Car Park Excavation & Earthworks
A durable asphalt car park starts with proper earthworks.
Where we're constructing a new parking area, we can complete the excavation and site preparation required before pavement construction begins.
This can include:
- Site clearing
- Topsoil removal
- Excavation
- Cut and fill
- Spoil removal
- Ground shaping
- Subgrade preparation
- Aggregate placement
- Compaction
- Drainage excavation
Managing the earthworks and asphalt as part of one project can also simplify coordination between the different construction stages.
Basecourse Preparation
The basecourse distributes vehicle loads and supports the asphalt above it.
Poorly prepared pavement layers can contribute to settlement, cracking, deformation and potholes.
Base preparation may include placing suitable aggregate in layers before grading and compacting the material to the required profile.
The pavement design should reflect the expected traffic. Areas regularly carrying heavier commercial vehicles may require a different pavement structure from parking areas intended primarily for passenger cars.
Car Park Drainage
Water is one of the most important considerations when constructing or upgrading an asphalt car park.
The finished pavement needs suitable falls so rainfall can move toward appropriate collection points rather than sitting in depressions.
Drainage planning may need to consider:
- Surface falls
- Channel drains
- Catchpits
- Kerbs
- Existing stormwater systems
- Building entrances
- Low areas
- Adjoining properties
- Existing concrete surfaces
Water entering weakened pavement can contribute to pothole development and pavement deterioration. NZTA specifically identifies water entering older or damaged pavement as a major contributor to pothole formation.
Heavy Vehicle & Industrial Car Parks
Not every car park carries the same loads.
Industrial sites may regularly accommodate delivery trucks, service vehicles, forklifts and other heavy vehicles.
These loads can place greater stress on the pavement, particularly in:
- Loading areas
- Turning areas
- Entrances
- Delivery zones
- Truck parking areas
- High-frequency traffic lanes
For these projects, the pavement structure needs to be considered in relation to the expected traffic rather than simply increasing the asphalt surface thickness.
Car Park Entrances & Accessways
The entrance to a commercial car park often experiences some of the highest traffic loads on the property.
Vehicles may brake, turn and accelerate repeatedly across the same section of pavement.
We can construct and repair asphalt entrances and accessways as part of a wider car park project.
Careful attention is given to transitions between the car park and surrounding surfaces so vehicle access remains practical.
Car Park Milling & Asphalt Overlays
Where an existing car park needs resurfacing, simply adding another asphalt layer may create unsuitable finished levels.
For example, raising the pavement can affect:
- Kerbs
- Drainage channels
- Building entrances
- Concrete slabs
- Manholes
- Service covers
- Vehicle entrances
Selected areas of existing asphalt can sometimes be milled or removed before resurfacing to maintain appropriate levels and create better tie-ins.
Christchurch City Council's current 2025 roading specification includes asphaltic concrete construction requirements, while its roading specifications also address surface preparation and pavement-related construction.
Car Park Pothole Repairs
Potholes should generally be repaired before resurfacing a car park.
A pothole can indicate deterioration extending below the visible opening.
The damaged area may need to be cut or excavated so failed material can be removed before the pavement is reinstated.
Patching and pothole repair are established forms of sealed-pavement maintenance in New Zealand.
Our Asphalt Car Park Process
Site Assessment
We assess the site, existing pavement, access, levels, drainage and expected traffic.
Scope the Project
We determine whether the project requires new construction, repairs, resurfacing or a combination of treatments.
Excavation & Preparation
Existing material is removed where required and the pavement foundation is prepared.
Basecourse Construction
Aggregate is placed, graded and compacted.
Drainage & Levels
The pavement is shaped to achieve suitable finished levels and surface drainage.
Asphalt Installation
The asphalt surface is installed across the prepared pavement.
Compaction & Finishing
The asphalt is compacted and transitions, edges and tie-ins are completed.

Asphalt Car Parks Christchurch Questions
Is asphalt suitable for commercial car parks?
Yes. Asphalt is widely used for commercial and higher-traffic pavements. NZTA notes that asphaltic concrete is generally harder wearing than chipseal and is used on high-traffic parts of New Zealand's road network.
Can an existing car park be resurfaced?
Often, yes. If the underlying pavement remains suitable, repairs can be completed before installing a new asphalt surface.
Can you repair potholes before resurfacing?
Yes. Failed sections should be assessed and repaired before the new asphalt layer is installed.
Can you extend an existing asphalt car park?
Yes, subject to site conditions, available space, drainage and the requirements of the property.
Do you handle excavation?
Yes. Excavation, earthworks and pavement preparation can form part of the complete car park project.
Can you resurface around manholes and drains?
Yes. Existing services and drainage structures need to be considered when establishing the finished asphalt levels.
