High Energy Impact Compaction

What is High Energy Impact Compaction?

High Energy Impact Compaction (HEIC) – as the name suggests – is a compaction technique that transmits rapid, high-energy impact in order to strengthen base materials and lay firm foundations for development.
The technique can be far more efficient and productive than conventional compaction methods – at around a quarter of the cost, and 50% quicker than traditional methods.

How HEIC compares to conventional compaction methods

HEIC can make light work of land that other compaction methods may not be able to reach – including reclaimed or otherwise inaccessible land – opening up new development opportunities.

The technique also enables compaction without disturbing what’s underneath. This is particularly useful in adverse soil conditions that may pose a risk to people or the surrounding environment when compacted.

Applications of HEIC

Land reclamation

Transforming water bodies into usable land areas such as container terminals.

Deleterious material

For sites containing hazardous material such as Acid Sulphate Soils (ASS), asbestos etc.

Mining & power infrastructure

Includes tailings dams, haul roads, and rehabilitation. Also used in the power industry, including wind farm power generation track lines and lay-down areas.

Civil infrastructure & development

Includes residential sub-divisions, airports, roads and ports.

Commercial & industrial

Includes business, production, commerce, manufacturing and trade services

Landfills

Creating extra volume and sealing from noxious gases.

In-situ Compaction

In-situ compaction refers to the improvement and stabilisation of existing base materials onsite, rather than importing external soil for the job. This can be more cost-effective and cause less disturbance to the surrounding environment.

High Energy Impact Compaction (HEIC) is a compaction technique that transmits rapid, high-energy impact in order to strengthen base materials and lay firm foundations for development.

HEIC can be far more efficient than conventional compaction methods – around a fraction of the cost, and significantly quicker than traditional methods. Our specialists can advise if HEIC is the right solution for your site.

High-energy impact compaction offers more efficient compaction for specific soil types, especially in larger construction projects. Regular compaction methods, while generally slower, are more versatile and can be used for a wider variety of soil types and situations. The choice between the two methods depends on project-specific factors and goals.

Impact compaction might be necessary for your site if you:

    • Have loose, granular soil with poor compaction properties
    • Need to enhance load-bearing capacity for structures
    • Want to mitigate settlement issue
    • Find it more cost-effective compared to other methods

 

Consulting a geotechnical engineer is crucial to make an informed decision based on soil tests, site conditions, and project requirements.

Landpac trades as Landpac Technologies Pty Ltd and is a wholly owned subsidiary of Conplant.
