Dynamic Compaction™ is used for the foundations of buildings or to stabilize large areas of embankments or roadways on loose soil. The technique is also commonly used to densify buried land fill materials.
The Dynamic Compaction technique, invented and developed by Louis Menard, achieves deep ground densification using very high energy waves. Steel weights (pounders) weighing 15 to 40 tons are released in free fall from a height of 30 to 120 feet. The arrangement of the impact points and the other parameters of the treatment (energies, phasing, rest periods) depend on the characteristics of the soil to be treated and on the results of the trial zone.
Advantages of Dynamic Compaction:
- Compacts areas of loose granular soils, uncontrolled fills or waste
- Increases density and collapses voids
- Increases the bearing capacity of granular soils
- Reduces the volume of landfills
- Reduces post-construction settlements
