HEIC engineering solution
High Energy Impact Compaction (HEIC) uses a towed polygonal roller to apply repeated dynamic loading as it travels across a planned work area. It is a ground-treatment method to be considered alongside material condition, layer arrangement, access and verification requirements, rather than a universal replacement for every compaction method.
For an engineering procurement discussion, the useful starting point is not a promised treatment result. It is a defined site brief: the material and moisture condition, required working area, treatment objective, available towing equipment, turn space, working gradient and acceptance route.

Method fit
Suitability is an engineering decision. The lists below help frame the first project discussion; they do not replace site investigation or acceptance criteria.
Complete working system
A polygonal roller assembly selected by the required energy class, working geometry and project configuration.
A dedicated or expressly specified tow tractor selected with the roller, not as an afterthought.
Hydraulic, nitrogen, spring and rubber damping elements manage the working connection and operating loads.
Where required, monitoring can support documented passes and project verification planning.
System configuration
The application, energy class, tow tractor, damping arrangement and working route must be checked together. A project RFQ should therefore include the work area, material, access and equipment already available on site.
Explore impact roller systemsProject workflow
Record material, moisture condition, area, target outcome, access, turning space and delivery programme.
Review roller energy class, tow tractor, damping arrangement, support equipment and monitoring needs together.
Set out passes, turning routes, exclusion zones and inspection points with the project team before operation.
Follow the planned speed, turning and ground-condition limits; stop and review when conditions change.
Use the project acceptance method and recorded work information to support the next construction decision.
Work controls
CMG manual guidance is used here to support safe planning. It does not remove the need for project-specific risk controls, competent supervision or local regulatory requirements.
Verification and monitoring
Define the project acceptance method before mobilisation; this may include inspection, field testing, survey, monitoring records or another project-specified route.
Equipment monitoring and project acceptance testing serve different purposes. Monitoring can document working passes; acceptance remains determined by the project specification and responsible engineering team.
Use any change in ground condition, equipment behaviour or work access as a trigger to review the work plan rather than assume a uniform result.

No. HEIC suitability depends on the actual ground, work area, access and project acceptance requirements. The method should be reviewed as part of the project engineering process.
The available CMG manual guidance calls for 10-15 km/h operation, avoidance of sharp or high-speed turns, and no operation on slopes above 30 degrees, muddy surfaces, unstable ground or pits.
Verification must follow the project specification. Equipment monitoring can support documented working passes, while acceptance testing is set by the responsible project engineering process.
