Driveways and Right of Ways

Chipseal can be constructed almost anywhere and is already frequently used on, New and existing: driveways, Right of ways, carparks, commercial yards, bike tracks, walkways, roads and Highways.

Chipseal's advantages ​​​

  • Chipseal has a long design life, especially on driveways we have re-sealed some driveways that have lasted 50 years. Generally driveway second coats / re-seals last around 30 years before reseal. An important factor to achieving this life span is to not allow your driveway to form significant pot holes before getting a re-seal. 

  • Chipseal can be constructed in a matter of hours and be ready for traffic immediately.

  • Complies with colour requirements for resource consents.

  • As a flexable surface it allows the ground to move below without cracking.

  • Lower CO2 impact on environment than alternatives.

  • The surface has a deeper texture than alternatives, allowing water to runoff without affecting safety, the deeper texture provides better grip and skid resistance.

  • As a guide on pricing:
    On larger driveways Chipseal is generally 4 times cheaper than Hotmix (Asphalt) and around 5 times cheaper than Concrete.
    On smaller driveways chipseal is still around half the price,
     when it starts to wear out a new surface can be constructed on top unlike concrete which has massive costs associated with the ripping up and removal of the concrete before the new driveway and even be constructed.

A Bit of Background
Chipseal originates from ancient roman times where large bricks or cobbles were placed onto thick oils. 
Modern roads are both more cost effective and easier to construct, capable of supporting larger vehicles at much faster speeds. 
Chipseal surfaces come in a variety of sizes and as a result have a varying range of texture and life span.

Frequently asked questions

Can chipseal be constructed on my esisting loose metal (unsealed) driveway?

Not without preperation work. For chipseal to be constructed fresh metal (Stones) must be laid and compacted. This is for a few reasons: - Unsealed roads loose their smaller stones and dust with water runoff and as a result the road only retains its larger stones. These larger stones without little ones to hold them in place start to act like marbles this is especially evident on sloped driveways. When cars slip on these stones they push them down the hill; further deteriating the driveway. - Most metal driveways are constructed out of poor strength aggregate, as we want the road way to last the next 100 years we cannot have soft stones breaking down under traffic. Especially not under your brand new road surface.

How long before I can use my driveway after chipseal is constructed?

You can drive on a chipseal surface immediately after constructon. It is recomended to get any work you need done involving heavy trucks using your driveway before constructing your new surface. This helps ensure you get the best life out of the surface.

Will there be loose stones after construction?

Yes there will, Generally these loose stones will be swept off with traffic and weather. These can be easily swept off in 6 months time at your request. Generally we recomend leaving the chipseal for this 6 months to allow the chipseal to properly bed in and set.

What is emulsion and what are its benefits?

Emulsion is the modern road sufacing product of choice. Producing it requires 45% less greenhouse gas emissions vs it's counterpart hot cutback bitumen. It also doesn't have any nasty additives, making it safer for our atmosphere and our workers. It is the only product allowed to be sprayed to glue down our moterways and is also the minimum requirement for lots of council roads. Why? Because emulsion is water based, it is able to penetrate into a roads surface and through dust. Stones are also permiable and allow water to infiltrate them allowing the product to adhear significantly beter to both the road and the aggregate.
