Ground Improvement is less expensive and time-consuming than pile installation. By compacting the soil as much as possible, it greatly improves the density of of the soil, therefore reducing the possibility that the soil underneath the foundation will subside and allow the building to settle. A distinct advantage of a building site which utilizes ground improvement over a piled foundation is that it can eliminate the cost of a structural slab, which can be a considerable amount of savings in the cost of building a structure. Deep Dynamic Compaction While simplistic in its nature, Deep Dynamic Compaction (DDC) remains an economic, proven and effective method of ground improvement. DDC is performed by dropping a heavy weight continuously over a site until a desired level of densification is achieved. This is usually verified by soil boring(s). Deep Dynamic Compaction, showing its relative effects on soil densification. Vibro Probe Compaction Vibro Probe Compaction is performed by vibrating a probe continuously into the ground until the required compaction has been attained.
