Dynamic Deep Compaction - Ground Improvement

Dynamic deep compaction (DDC) is an important ground improvement technique, capable of compacting a wide variety of weak soils. The ground improvement results in increased bearing capacity and reduced settlement. In this way soil conditions on many marginal sites can be improved to the point where shallow foundations can be used without recourse to deep excavation or piling.

Vibro Compaction

This ground improvement process is used in fully saturated and very weak soils. Water jetting removes soft materials, stabilises the hole and allows the stone backfill to reach the bottom of the vibrator. This is then compacted and interlocked with the surrounding soil.

Vibro Stone Columns

Keller's Vibro Replacement method of constructing stone columns through fill material and weak soils, for overall ground improvement and to improve their load bearing and settlement characteristics, provides an economic and technically sound solution to a wide range of geotechnical and foundation problems.
