Rapid Impact Compaction Rigs. For ground improvement in general three different methods can be recognized. For cohesive soils such as sand, gravel and some silty sands, compaction methods are a good solution for ground improvement. In case soils are difficult to compact such as clay, peat and soft silt layers soil replacement could be the solution.
