Product Overview

Grano Dust supplied in a 800kg bulk bag, consisting of finely crushed granite aggregate screened to 0-5mm.

Often referred to as granite dust, the name comes from its origin as a by-product of granite crushing, where granum (Latin for grain) reflects its fine grading. 

When compacted, it forms a smooth, stable base that hardens while still allowing drainage, making it suitable for screeds, paving, driveways, paths, and artificial grass installation.

Features & Benefits

• Hardens when compacted damp: Binds together to form a rock-like base while remaining permeable.
• Free-draining structure: Prevents pooling and frost heave by allowing water to pass through.
• Weed suppression: Dense compaction helps inhibit weed growth, reducing maintenance.
• Improves concrete strength: Enhances compressive strength in screeds, mortars, and fine concretes.
• Smooth finish support: Provides an even bedding layer that reduces movement and lipping in paving or turf.
• Moisture management: Can be blended with soil to aid water retention for planting.
• Cost-effective byproduct: Typically more economical than primary aggregates of similar grading.
• Bulk bag format: Delivers ample volume for large projects such as driveways, hard standings, and landscaping works.
• HIAB crane offloading: Delivered via a vehicle equipped with a heavy-duty crane arm to allow for precise kerbside placement. Ensure the delivery site has sufficient access for a large HGV and is clear of overhead obstructions for crane operation.

Please Note: Colour and texture vary naturally depending on source. Bulk bag weight may differ by ±5% due to moisture content.

Applications

• Flooring screeds and mortar mixes: Blends with sand and cement to create durable, level screeds with improved strength.
• Driveways, paving, and paths: Compacts to provide a smooth, stable sub-base beneath slabs, blocks, or concrete.
• Artificial grass installation: Used with MOT Type 1 to provide a stable, permeable base for synthetic turf.
• Sports and industrial flooring: Suitable for fine concrete bases in garages, workshops, factories, and sports courts.
• Hard standings and capping layers: Used to top sub-bases or form durable, flat surfaces for landscaping.
• Soil improvement: Mixed into soil to improve moisture management and aid growing conditions.
  
  

Installation Guidance

• Spread and compact in thin layers: Ensures uniform stability and prevents settlement.
• Moisten slightly before compacting: Aids binding, allowing the dust to harden into a firm surface.
• Combine with MOT Type 1 where required:Provides added depth and stability for heavy-duty bases.
  
  

Compliance & Performance

• Aggregate grading: Screened to 0-5mm for consistent compaction and bedding performance.
• Service class: Suitable for external landscaping, sub-bases, screeding, concreting, and fine flooring applications.
