20mm Down

20mm Down is a graded aggregate composed of crushed stone, gravel, and fine particles that range in size from 20mm down to dust. This combination creates a compactable material that is perfect for use as a sub-base in construction projects. The fine particles fill the gaps between the larger stones, providing a firm and stable base that is essential for supporting heavy loads and ensuring a long-lasting surface.

Typical Uses & Benefits

• Sub-Base Layer: Ideal for use as a sub-base layer for roads, driveways, pathways, and patios, providing a firm and stable foundation that can support heavy traffic.
• Compaction: Its blend of different particle sizes allows for excellent compaction, creating a solid base that prevents shifting and settling over time.
• Landscaping: Can be used in landscaping projects to create level surfaces for laying turf, paving slabs, and other decorative elements.
• Drainage: While it compacts well, the mix of sizes still allows for adequate drainage, reducing the risk of water pooling on surfaces.
