What Is a Two-Coat Bitumen Driveway?
A two-coat bitumen driveway, also known as a two-coat seal or a bitumen spray seal, is a durable and cost-effective surfacing solution commonly used for residential driveways, rural properties, and commercial spaces. It provides a strong, weather-resistant finish that can handle heavy traffic while maintaining a smooth and visually appealing surface.
How Does a Two-Coat Bitumen Driveway Work?
The process involves applying two layers of bitumen (a sticky, tar-like substance) with a layer of aggregate (pre coated stone) in between. Here’s how it works:
- Surface Preparation – The area is excavated and levelled, with a road base compacted to create a solid foundation.
- First Coat Application – Hot bitumen is sprayed over the base, followed by a layer of aggregate, which is rolled in for maximum adhesion.
- Second Coat Application – Another layer of bitumen is applied, followed by a second layer of aggregate, further strengthening the surface.
- Compaction and Curing – The final layer is compacted to ensure a smooth, long-lasting finish. Over time, the driveway settles, creating a hard-wearing surface.
Why Choose a Two-Coat Bitumen Driveway?
- Cost-Effective: More affordable than asphalt or concrete while still offering durability.
- Weather Resistant: Handles harsh Australian climates, including heat and heavy rain.
- Low Maintenance: Requires minimal upkeep compared to other surfaces.
- Longevity: When properly installed, it can last 15+ years with periodic resealing. Versatile Aesthetic: Available in different aggregate colours to complement your property.
