What is Dynamic Compaction?

Invented by Louis Ménard in the 1960s, Dynamic Compaction is a leading soil improvement technique that has already been used on several thousand structures around the world.

Dynamic Compaction is a method used to enhance the mechanical characteristics of soil by densifying it at depth using a mass that impacts the soil surface. This technique is particularly efficient for improving loose, low-bearing soils, such as sand, without the need for adding any extra materials, making it an environmentally friendly option.

The Dynamic Compaction technology, also known as dynamic consolidation, is a technology invented and developed by Menard. This technology was extensively tested and optimised hence its safe and economic application today.

Dynamic Compaction Process

Technical Details

Mass of the weights: 10 to 40 tons

Maximum Compaction Depth: 10 to 15 meters (depending on soil type and grading)

Rate: 2 to 5 blows per minute

Unit Energy per Impact: 100 to 700 tons per meter

Steps Invoved

Dynamic compaction involves dropping a mass (between 10 and 25 tonnes) onto the soil in a predefined grid. The impacts are repeated according to a pattern designed by Menard Asia’s team, considering the soil type and the requirements of the structure to be built.

For deeper compaction (up to 15 meters) or exceptional mechanical performance, the drop weights can be increased up to 40 tonnes, with a lifting height reaching 30 meters.

Equipment and Tools

The technique typically uses crawler cranes weighing between 80 and 120 tonnes, specifically designed for dynamic compaction.

These cranes are fitted with features to handle the significant weights used in the process, ensuring precise and efficient execution.

Applications of Dynamic Compaction

Multi-storey buildings
Residential and commercial buildings
Roads and railways
Logistics areas and industrial buildings
Contaminated industrial land and landfill sites

Menard Quality Assurance

Menard Asia ensures the effectiveness of dynamic compaction through continuous monitoring and testing:

Pre-construction: Test boards are set up to analyze soil conditions.
During construction: Inspections are conducted to ensure compaction efficiency.
Post-construction: Geotechnical tests such as Menard pressiometer tests or plate loading tests are carried out to verify the results.

Additionally, Menard works on measuring and controlling vibrations generated by the technique, especially in urban areas to ensure minimal disruption to nearby structures.
