Understanding Spray Seal Aggregate and Surface Texture
Spray seal is a bitumen-based surfacing method used on driveways, rural access roads, private roads and other paved areas. It combines a sprayed binder with a layer of aggregate, also called stone or cover material. The binder holds the aggregate in place, while the stone forms the exposed surface that provides texture and contributes to grip and durability. For Brisbane driveway surfacing, the choice of aggregate and the way it is applied affect how the finished surface
A long driveway can collect and channel a surprising volume of water, particularly during the intense rain events common in Brisbane and across South East Queensland. If runoff is not managed, it can erode gravel shoulders, wash out the driveway base, create slippery patches, carry sediment onto roads or damage nearby landscaping. On sealed surfaces, water that cannot drain away may pool, seep through cracks and contribute to potholes or premature deterioration. Improvin
