Rapid Impact Compaction

Rapid Impact Compaction can be used to increase the bearing capacity of soils through controlled impact.A drop weight of 3 to 20 tonnes (depending on model) is dropped onto a special foot assembly 30 to 80 blows per minute. RIC is effective for compaction of upper layers of ground typically up to 1- 9m depth.

Soil compaction is used to densify loose granular soils and loam fill and industrial brownfield sites for surface compaction, foundations, liquefaction mitigation, and waste stabilization. Rapid Impact Compaction is a foundation improvement method that effectively compacts loose granular soils using hydraulic hammers that repeatedly strike an impact plate on the ground at 30 to 80 times per minute. RIC is effective for compaction of upper layers of ground typically up to 1- 9m dept. RIC technology is suitable for a wide range of non-cohesive soils, and is particularly suited to the compaction of gravel and sand.

The most common models mounted on excavators are HC150 HC180.

HC150 Rapid impact compactor

How it is applied?

The compaction foot installed to the hammer is placed on the marked location. After positioning the hammer, operated from the excavator cabin, is activated. Inside the frame, a drop weight is lifted to the predetermined height and dropped onto the compaction foot. The foot remains in contact with the ground while the drop weight repeats its sequence up to 80 blows/min. This process is repeated until the compaction criteria are met. The operator positions the hammer to the next marked location and repeats the process.

Soil compaction is used to densify loose granular soils and loam fill and industrial brownfield sites for surface compaction, foundations, liquefaction mitigation, and waste stabilization. 

The excavator converted rapid impact compactor utilizes the hydraulic power output from the excavator to continuously strike and tamp the ground. With high efficiency, high flexibility and easy operation, the excavator conversion rapid impact compactor is widely used in various construction scenarios and can meet the tamping needs of different foundations.Proper soil compaction is crucial for both small and large construction projects because it increases soil density and load bearing, ensuring the stability, durability, and longevity of buildings and structures. Choosing the right compaction equipment is the starting point for any effective compaction strategy.

The most common models mounted on loaders are HC42 .

The rapid impact compactor is a dynamic compaction device based on the piling hammer technology used to increase the bearing capacity of soils and reduce the settlement through controlled impacts, in particular, to compact sandy soils, where silt and clay contents are low. This ground improvement technique, which is allied to dynamic compaction, is called Rapid Impact Compaction (RIC). The general idea of this method is to drop a falling weight from a relatively low height onto a special foot assembly at a fast rate, while the foot remains in contact with the ground at all times.
