High Energy Impact Compaction: a planned ground-treatment method using a towed polygonal roller.
Impact compaction glossary
Use this guide to make the project discussion more precise.
A shared vocabulary helps buyers and engineers compare compaction methods without confusing machine labels, operating records and acceptance evidence.
This glossary explains terms used across CMG impact roller, hydraulic compaction and verification pages.

Guide contents
Questions a technical buyer should resolve before selection.
RIC
Rapid Impact Compaction: a hydraulic, controlled-impact route reviewed with carrier, access and work-zone requirements.
Impact roller system
The complete working set, including roller, tow unit, damping arrangement, operating space and any monitoring route.
Verification
Project-defined inspection or testing used to make the acceptance decision; distinct from machine process records.
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 use a glossary term as a technical specification.
- Do not assume one method or model is interchangeable with another.
- Confirm definitions against the relevant manual and project specification.
Buyer checklist
Prepare these inputs before sending an RFQ.
- Application and ground condition
- Work area and access
- Available power or carrier equipment
- Required documentation
- Acceptance 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.
