Material input
Describe rock type, grading, moisture, fill history and placement arrangement.
Rock fill compaction guide
Use this guide to make the project discussion more precise.
Rock fill compaction requires attention to material grading, layer or fill arrangement, equipment energy route and access.
This guide prepares a buyer to discuss rock fill or hard material with CMG without claiming a universal result.

Guide contents
Questions a technical buyer should resolve before selection.
Equipment route
High-energy impact or hydraulic compaction may be considered after material and site review.
Site control
Turning space, access, gradient, dust and adjacent works affect the work plan.
Verification
Field inspection or testing follows the project specification.
Evidence boundary
A useful guide is clear about what it does not prove.
CMG uses this resource to organise a project conversation. It does not replace site investigation, geotechnical design, equipment documentation or the project acceptance specification.
- Do not select an impact roller by energy label alone.
- Do not present machine activity as proof of rock fill acceptance.
- Review material changes before continuing the work plan.
Buyer checklist
Prepare these inputs before sending an RFQ.
- Rock or fill description
- Grading and placement history
- Work area and access
- Available power or carrier equipment
- Acceptance and testing route
Decision record
Turn the research question into a reviewable equipment brief.
Use the following record as a handover between procurement, site engineering and the equipment supplier. Empty fields are signals to investigate, not assumptions to fill with a generic machine claim.

Further questions for the project team.
What rock fill information is needed?
Rock type, grading, moisture, placement history and project acceptance requirements.
Can one roller handle every rock fill?
No. Material, grading, access and project objective need specific review.
What should the work plan include?
Access, turning space, equipment movement, controls and verification points.
How is rock fill accepted?
By the project-defined inspection or testing process.
