GAP 40
Our GAP 40 is a strong, medium-coarse basecourse with particles ranging from fines up to 40mm. Designed for deeper foundations and high-load environments, GAP 40 is a robust option for driveways, commercial accessways, and roading sub-bases.
Because it contains both fines and coarse aggregate, it compacts into a hard, durable layer capable of supporting significant vehicle and machinery traffic.
Ideal Applications
- Heavy-traffic driveways & rural access roads
- Roading sub-base layers
- Commercial or industrial construction pads
- Hardstand areas
- Base layers under deeper structural fill
- Stabilization layers in civil works
GAP 40 provides durability where stronger foundations are required.
