Ground Improvement - Do you know how the Rapid Impact Compaction works

Rapid Impact Compaction uses a hydraulic hammer for shallow compaction of loose soils to increase density and reduce settlement

The technology of the Rapid Impact Compaction (RIC) was implemented in the 1990s as complementary to other methods of the dynamic soil compaction with limited impacts to the structures within the vicinity of the worksite. Rapid Impact Compaction (RIC) is one of the mechanical ground improvement techniques that is suitable for granular soil material.

The principle of this method is repeatedly striking an impact plate on the ground surface using a hydraulic hammer. Menard Asia’s RIC rig is typically an excavator with a 9-tonne high-frequency hydraulic hammer (approximately 1 blow per second) capable of dropping the hammer at a maximum height of 1.2 m to densify the soil. Energy is transferred to the underlying loose granular soils rearranging the particles into a denser formation. RIC can effectively densify in-situ soils up to thickness of 4 to 5 m. It can also be used for fill material compaction, which can place in bulk fill and compacted accordingly at a greater thickness than conventional roller compaction.

For large infrastructure developments, RIC takes the lead due to its speed of execution which makes it much more cost-efficient than conventional compaction method.
