With the development of the CDC technique, a rapid impact compaction (RIC) technique, Cofra has a product available, which is cheap, fast and reliable. The technique compacts the underground fast, homogeneously and with a high accuracy. Dependent on the substrata and the applied energy, the CDC technique is capable of compacting the soil till a depth of 9 meters below the surface. This is mainly due to the use of 16 tonne hammers, a state of art monitoring system and highly controlled compaction operations. The method is highly economical and is capable to compete with dynamic compaction and other rapid impact compaction techniques.
High level of quality control
The compaction operation is controlled by the use of an advanced real time GPS guided monitoring system, measuring amongst others, the settlement and settlement rate of the foot. The effort is adjusted to the local ground conditions creating a more homogeneous subsoil after compaction. Our Geotechnical engineers are at hand to review data and make site specific correlations between the monitoring data and requirements.
