About
High Energy Impact Compaction

High Energy Impact Compaction (HEIC), also known as Impact Roller Compaction, is a ground improvement technique that densifies near-surface granular soils and fills by applying high-energy impacts through a specially shaped impact roller. The process increases soil density, improves bearing capacity and reduces settlement, providing an efficient solution for large industrial, commercial and infrastructure developments.

With extensive expertise in impact ground improvement, Menard designs each High Energy Impact Compaction solution according to the site’s geotechnical conditions, structural requirements and performance objectives. Every installation is carried out under rigorous quality control procedures to ensure consistent treatment quality, reliable ground improvement and compliance with project specifications.

Improving large areas through high-energy impact rolling

High Energy Impact Compaction (HEIC) is a ground improvement technique that improves the engineering properties of near-surface granular soils and fills by applying repeated high-energy impacts through a specially designed impact roller. The process increases soil density, improves bearing capacity and reduces settlement, providing a reliable foundation solution for industrial developments, transport infrastructure and large earthworks projects.

Unlike conventional compaction equipment that primarily densifies the upper soil layers, High Energy Impact Compaction transmits high levels of impact energy deeper into the ground while maintaining exceptional productivity over large treatment areas. This approach makes it particularly effective for improving engineered fills, reclaimed land and mine waste materials, providing an efficient, economical and sustainable solution for a wide range of ground improvement projects.

Advantages

  • Improves bearing capacity and reduces total and differential settlement.

  • Achieves greater treatment depths than conventional smooth drum roller compaction.
  • Provides a fast and cost-effective solution for improving large treatment areas.
  • Enables thicker fill layers to be compacted, reducing construction time and earthworks operations.

  • Loose granular soils.

  • Engineered and uncontrolled fills.
  • Reclaimed land.
  • Mine waste and other granular earthworks materials.

  • High-energy impact roller with triangular, square or pentagonal drum geometry.

  • Towed behind a tractor or similar towing vehicle.
  • Treatment carried out through multiple overlapping passes across the treatment area.
  • Compaction depth and number of passes are adapted to the project’s geotechnical and performance requirements.

High Energy Impact Compaction is carried out using a specially designed impact roller towed behind a tractor or similar vehicle. As the roller travels across the treatment area, its non-circular geometry generates repeated high-energy impacts that are transmitted into the underlying soil, achieving greater compaction depths than conventional roller compaction.

The treatment is performed through a series of overlapping passes, with the number of passes and rolling pattern determined according to the site’s geotechnical conditions and performance objectives. Throughout the installation process, key parameters such as roller configuration, number of passes, treatment coverage and ground response are monitored to ensure consistent treatment quality and compliance with project specifications.

Frequently Asked Questions

What is High Energy Impact Compaction (HEIC)?

High Energy Impact Compaction (HEIC) is a ground improvement technique that densifies near-surface granular soils and fills using a specially designed impact roller. The repeated high-energy impacts increase soil density, improve bearing capacity and reduce settlement, creating a more stable foundation platform.

When should High Energy Impact Compaction be used?

HEIC is commonly used to improve large areas of fill or loose granular soils for industrial developments, transport infrastructure, ports, airports and large earthworks projects. It is particularly well suited where rapid treatment over extensive areas is required.

What types of soils are suitable for High Energy Impact Compaction?

HEIC is most effective in loose granular soils, engineered fills, uncontrolled fills and reclaimed land. A geotechnical investigation is carried out to determine the suitability of the technique for the site’s specific ground conditions.

How does High Energy Impact Compaction improve the ground?

The technique uses a non-circular impact roller that generates repeated high-energy impacts as it is towed across the treatment area. These impacts transmit energy into the ground, densifying the soil and improving its engineering properties.

What are the advantages of High Energy Impact Compaction?

HEIC provides a fast and economical solution for improving large treatment areas. It increases bearing capacity, reduces settlement and achieves greater treatment depths than conventional roller compaction while maintaining high productivity.

How does High Energy Impact Compaction differ from conventional roller compaction?

Unlike conventional smooth drum rollers that mainly compact surface layers through static weight and vibration, HEIC uses a specially designed impact roller to generate high-energy impacts that transmit deeper into the ground, providing more effective improvement of near-surface soils.

Quality control includes monitoring the treatment pattern, number of passes, roller configuration and ground response throughout the compaction process. Field testing before and after treatment is performed to verify that the required ground improvement objectives have been achieved.

High Energy Impact Compaction is an efficient solution for improving large areas of granular soils and fills where productivity, treatment depth and cost-effectiveness are key project requirements. Its ability to compact thicker fill layers can also help reduce construction time and earthworks operations.
