Granular sub-base is the drainage and load-spreading layer beneath the base course. We supply graded aggregate and lay it evenly so water moves out and wheel loads spread out.
Scope of work
- Supply of graded granular material
- Spreading by motor grader to uniform thickness
- Water sprinkling and vibratory roller compaction
- Level and thickness checks before the next layer
Quality and standards
Gradation, plasticity and compaction are tested against the contract grading, with records kept for every stretch.
All works are executed with safety planning, trained crews and clear reporting to the client.
