Essential Questions for Your Asphalt Contractor
When selecting an asphalt contractor, you'll need to verify five critical areas before signing any agreements. Start by confirming their current business licence and insurance coverage, including workers' compensation and public liability (minimum $1M). You should request a detailed project timeline, material specifications that meet Australian Standards AS2150, and a thorough cost breakdown. Don't forget to verify their service area coverage to avoid unexpected travel charges. Proper scrutinising of these key aspects will help guarantee your project meets industry standards and delivers lasting results. Understanding these fundamentals is just the beginning of securing a quality asphalt installation.
License and Insurance Status
Confirming your contractor's licence and insurance status should be your first priority before signing any agreements.
You'll want to verify that your chosen contractor maintains current licensing and meets all local regulatory requirements. This verification process safeguards you from potential liability issues during and after the project.
When evaluating contractor qualifications, request documentation of:
- Current business licence
- Workers' compensation insurance
- Public liability coverage (minimum $1 million recommended)
- Motor vehicle and equipment insurance
- Professional indemnity insurance
Don't hesitate to contact their insurance provider directly to verify policy status.
Project Timeline and Scope
A clear understanding of project timelines and scope is essential before starting any asphalt work.
You'll want to discuss your project's specific requirements with your contractor and organise detailed information about the expected project duration. Most asphalt jobs can take anywhere from half a day to several days, depending on the size and complexity of your project.
Ask your contractor about their client communication process during the project. They should provide you with:
- A detailed timeline from start to finish
- Information about the surface preparation phase
- Expected curing times
- When you can resume normal use of the area
Remember that weather conditions can affect scheduling, so it's important to discuss potential contingency plans and how your contractor handles unexpected delays or changes in scope.
During the summer months, particularly in neighbourhoods with high temperatures, your contractor should advise on optimal working conditions to ensure proper curing and colour consistency.
Material Quality Standards
Understanding material quality standards remains critical when selecting an asphalt contractor.
You'll want to ensure your contractor follows strict asphalt durability standards and maintains transparent bitumen sourcing practices. Quality materials directly impact your project's longevity and performance.
- Check that your contractor uses materials meeting Australian Standards AS2150 for hot mix asphalt.
- Request documentation on bitumen content percentages (typically 4.5-6.5% for driveways).
- Verify the contractor's aggregate testing procedures and quality control measures.
- Confirm they maintain consistent temperature controls during installation (140-160°C).
When you're discussing your project, don't hesitate to ask about material specifications.
A reputable contractor will gladly explain their quality control processes and provide documentation of their material standards compliance.
Cost Breakdown Details
Delving into cost breakdown details helps you avoid surprises when planning your asphalt project. When reviewing quotes, you'll want to ensure they include:
- Base preparation costs
- Material quantities and rates
- Labour expenses
- Equipment charges
- Any additional services required
Several pricing factors influence your final cost, including access to the site, surface preparation needs, and total square metres. You'll need detailed quotes that break down each component separately, providing quote clarity for your budgeting.
Ask your contractor about potential variables that could affect the final price, such as:
- Drainage requirements
- Soil condition amendments
- Edge treatment options
- Traffic control needs
- Specific finish requirements
Always request written documentation of all costs to maintain transparency throughout your project.
Service Area Coverage
Beyond understanding project costs, you'll need to confirm whether your location falls within a contractor's service range.
Service area verification is essential before organising your asphalt project, as contractors typically have specific service area limits that affect both availability and pricing.
- Check the contractor's website for an interactive service area map
- Verify if your location falls within their standard coverage radius
- Ask about additional travel charges for locations near boundary areas
- Confirm specific suburb coverage, as some areas may have restrictions
When dealing with NK Asphalt, you'll find their service territory extends from Mandurah in the south to Two Rocks in the north, and as far east as York and Northam.
This extensive coverage guarantees they can effectively serve both Perth metro and outer regions while maintaining quality service standards.
Frequently Asked Questions
How Long Should I Wait Before Parking Vehicles on the New Asphalt?
You'll need to wait 24 hours before parking on your new asphalt for light vehicles. However, it's best to follow specific parking guidelines during the full asphalt curing process.
Can Asphalt Be Laid Over My Existing Concrete or Brick Paving?
While asphalt compatibility varies, you can lay it over concrete if it's stable and crack-free. However, it's not recommended over brick paving due to potential surface movement and material separation.
What Preparation Work Is Required Before Installing Asphalt on My Property?
You'll need a site assessment and soil testing first. Then you'll require proper drainage, clearing vegetation, levelling the ground, and compacting the base material before asphalt installation.
Do You Offer Different Color Options for Asphalt Surfacing?
You'll find that traditional bitumen comes in black, but you can enhance its appearance with colour selection through special sealers or design options like decorative patterns and borders.
How Often Should I Reseal or Maintain My Asphalt Driveway?
You'll need to reseal your asphalt driveway every 3-5 years to maintain its lifespan. Regular maintenance includes crack repairs, cleaning, and addressing drainage issues to prevent premature deterioration.
