Rapid Impact Compaction


What is rapid impact compaction?

Rapid impact compaction is a high-frequency controlled energy soil compaction technique used to densify surface layers of soils (to a depth of 5 to 7 metres in most cases) with minimum impact on the immediate worksite environment.


What resources are used?

A compaction plate is placed on the ground to be treated and a hydraulic hammer, generally weighing less than 10 to 15 tonnes, is fitted to an excavator and used to transmit compaction energy to the soil via repeated impact.


In what circumstances is it applied?

Rapid impact Compaction is widely used to densify loose granular soils (sand or gravel) as well as loam fill and industrial brownfield sites.


I need to compact the ground near an adjacent site. Can I use this technique?
The technique is suitable for use in small spaces, such as within or next to existing warehouses. In such cases, vibrations in adjacent structures are carefully monitored during rapid impact compaction.
