Product Overview
20kg Kiln Dried Paving Sand is a fine, silica-based jointing sand that has been industrially kiln-dried to achieve exceptionally low moisture content. The material is specifically designed for brushing into the narrow joints of block paving and paving slabs, ensuring complete joint penetration and uniform compaction.
Its ultra-dry and free-flowing texture allows efficient filling of even the smallest gaps, creating a strong interlock between pavers that prevents lateral movement and improves overall stability. Once brushed in, the sand supports the structural integrity of the paved surface while helping to inhibit weed growth between joints.
Supplied in convenient 20kg bags, it is immediately ready for use in domestic or commercial paving projects, including driveways, patios, and pathways.
The consistent particle grading and clean, dry finish ensure fast, accurate application and a durable, professional result. Each bag contains 20kg of kiln-dried fine silica sand.
Features & Benefits
- Fine silica composition: Uniform, angular grains penetrate deeply into joints for maximum interlock and surface stability.
- Kiln-dried for reduced moisture: Ensures free-flowing performance and efficient filling, even in narrow paving joints.
- Enhanced structural integrity: Locks pavers in position, preventing shifting, rocking, or edge spalling under traffic loads.
- Weed inhibition: Creates a dense joint matrix that discourages weed seed germination and growth.
- Consistent grading: Screened and processed for reliable jointing performance without oversized particles or dust.
- Improved surface drainage: Allows minor percolation of water through joints, supporting natural run-off management.
- Easy to apply: Free-flowing texture makes sweeping into joints quick and precise.
- 20kg bag supply: Convenient for small to medium projects, reducing handling effort and waste.
Applications
- Block paving joints: Designed for brushing into joints between concrete or clay block pavers on driveways, patios, and pedestrian areas.
- Re-sanding existing paving: Ideal for topping up jointing sand lost through weathering, cleaning, or settlement.
- Small-scale maintenance: Suitable for maintaining joint stability and surface appearance in high-traffic paved areas.
- Domestic and commercial paving: Applicable for both residential and light-use commercial installations.
Installation Guidance
- Ensure dry conditions: Only apply when paving and sand are completely dry; moisture prevents effective joint filling.
- Prepare surface: Clean paving of all debris and ensure blocks are properly compacted and level.
- Spread evenly: Pour sand generously across the dry surface and brush in multiple directions to fill joints fully.
- Compact thoroughly: For new installations, use a vibrating plate compactor with a protective mat to settle sand into joints.
- Top up as needed: Refill any settled joints after compaction to achieve full depth and strength.
- Final finish: Sweep off all excess sand to prevent surface abrasion or staining.
- Maintenance: Check joints periodically and reapply sand as required after cleaning or heavy rainfall.
Compliance & Performance
- Material specification: Fine kiln-dried silica sand, industrially processed for paving jointing applications.
- Moisture content: Extremely low moisture level for maximum free-flow performance.
- Grading and consistency: Produced to uniform particle size for predictable joint fill and stability.
- Suitability note: Not intended as bedding sand or for use in mortar or concrete mixes.
- Storage: Store in sealed bags under dry cover to maintain free-flow condition.
- Important note: Apply only in dry weather to ensure proper joint filling and long-term surface performance.
