DustSeal is a reliable and effective treatment engineered to suppress airborne dust on unsealed roads. Applied as part of routine maintenance, the process includes grading, compaction, and aggregate placement, finished with a specialised bitumen emulsion capping. The result is a durable, dust-free mastic surface that improves safety, extends maintenance intervals, and reduces lifecycle costs.
By locking in fine particles, DustSeal also protects surrounding land from dust contamination and prevents sediment runoff into nearby waterways. It delivers a cleaner, more stable unsealed road surface with fewer disruptions — making it a practical and environmentally responsible solution for managing rural and low-volume road networks.
