Frequently Asked Questions

These are some of the most common questions people ask about road base construction for driveways, carparks and roads.

  • What is road base made from?

    Road base is made from a mix of crushed rock, gravel, recycled concrete or quarry material. The size of the material varies but is compacted into a dense layer that forms the structural foundation for asphalt or bitumen. This base provides strength, supports heavy loads and allows water to drain away, preventing damage to the finished surface.

  • Why is road base important before laying asphalt?

    Without a strong road base, asphalt or bitumen surfaces are more likely to crack, sink or fail over time. The base distributes the weight of vehicles evenly and prevents moisture from weakening the surface. Skipping or poorly preparing the road base leads to costly repairs down the track, making it one of the most important steps in construction.

  • How thick should a road base be?

    The thickness of a road base depends on the type of surface and expected traffic. Residential driveways may need a 100–150mm thick base, while carparks and roads handling heavier vehicles may require 200–300mm or more. Proper compaction at each layer is essential to ensure the base is strong, stable and ready for asphalt or bitumen.

  • Can you repair a damaged road base?

    Yes, damaged or unstable road base can be removed and replaced. Repairs involve excavating the affected area, compacting fresh base material and testing for stability before resurfacing. Addressing road base issues early prevents more serious surface damage and keeps your asphalt or bitumen working as it should.

Built to Last

Road base is the unsung hero of any quality driveway, carpark or road. We prepare and compact the sub-base using crushed rock and gravel to create a stable surface that prevents cracking and movement. Once complete, we apply asphalt or bitumen for a smooth finish. A strong road base keeps your surfaces safe, functional and looking great for years to come.
