Geo Type 3

Type 3 aggregate is an open-graded, free-draining sub-base material produced from crushed stone and manufactured using a proprietary blend of graded aggregates to achieve consistent performance and permeability. Typically supplied to a 4/40 mm grading with reduced fines and controlled particle distribution, it provides excellent drainage while maintaining structural stability, making it ideal for permeable pavements, driveways, and hardstanding areas where both load-bearing capacity and water management are required.

​

Common Uses:

• Permeable road and driveway sub-bases

• Soakaways and infiltration layers

• Car parks and paved areas with drainage requirements

• Sports and landscaping foundations
