      What is spray sealing? + -
      Spray sealing is a pavement treatment where hot bitumen is sprayed onto a road surface, followed by the application of aggregate (stone). This process creates a durable, weather-resistant seal that enhances skid resistance. It is commonly used on regional and rural roads due to its cost efficiency and quick turnaround
      What is a prime seal? + -
      A prime seal is a preparatory bitumen application used on unsealed or granular road bases. It penetrates and binds loose materials, providing a stable surface for subsequent spray sealing or asphalt works. Prime seals help ensure long-term performance by improving adhesion and reducing moisture ingress.
      What is the difference between spray seal and asphalt? + -
      Spray seal is generally more cost-effective and faster to apply, making it suitable for lower-traffic roads and regional networks. Asphalt provides a longer-lasting, smoother finish that performs better under heavy traffic loads. The choice depends on the road’s intended use and required lifespan.
      How long does the process take? + -
      Spray sealing is typically completed within a day, depending on site conditions and weather. Asphalt works may take longer due to additional preparation and curing time. We work efficiently to minimise disruptions and ensure timely project delivery.
