$57.14 per t
Popular Use Cases
-
Drainage Systems – Primary use in French drains, land drains, and soakaways where cost-effective drainage performance is essential
-
Sub-base Material – Foundation layer for driveways, paths, and hardstanding areas requiring stable, well-draining support
-
Septic Tank Soakaways – Ideal for septic system drainage fields and percolation areas due to excellent water flow characteristics
-
Concrete Aggregate – Coarse aggregate component in concrete mixes for foundations, footings, and general construction work
-
Pipe Bedding – Surround material for underground utilities and drainage pipes, providing support and drainage
20mm Purple/Red aggregate is a cost-effective alternative to standard 20mm drainage aggregate, offering the same functional performance at a reduced price point. This crushed stone material consists of angular fragments measuring approximately 20 millimeters in diameter and occasionally exhibits purple or red coloration due to the natural mineral content of the source rock. While the color variation is incidental rather than intentional, it provides the same excellent drainage and structural properties as conventional drainage aggregate.
Additional information
| cost-effective | Significantly cheaper than standard drainage aggregate while maintaining equivalent performance specifications |
|---|---|
