With the benefit of our Barmac crushers and considerable experience we are able to supply sealing aggregates with exactly the right angular shape to maximise skid resistance and stay locked into the binder material.

Our premium sealing chips lengthen the life of the roading surface.

Quality Assurance
Holcim Aggregates' laboratories at Bombay and Hastings provide the cornerstone of our quality control by undertaking a variety of pre-production, in-process and finished product testing to ensure our sealing chips meet the desired specifications.

All quarries have comprehensive control systems in place. Under our lot management system, each lot is allocated a unique number which allows us to supply customers with a complete product history, including test reports.

Our investment in new technology allows us to meet the increasingly fine tolerances desired in the market.

Applications:
Once bound with bitumen, sealing chip provides an all weather surface for roads, driveways and car parks, which can improve skid resistance.

Particle shape and surface texture are important in providing a stable road layer. Surface friction characteristics are particularly important after aggregates are exposed due to wear and then subjected to critical conditions, including high traffic volumes and wet weather. A wide variation of sizes are available.
