Dynamic Compaction is a compaction method which has been around for more than 60 years. It is a simple method with a great impact. A pounder is dropped in free fall from a specified height onto the surface to compact the soil. Cofra uses this technique in situations where our other compaction systems do not meet the criteria in an economical way or where our other methods are not allowed. With a depth of influence of over 12 meters, the technique has a larger depth of influence when compared to our CDC compaction hammers. Cofra uses the dynamic compaction with state of art monitoring systems to make the process as controlled as possible.
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 pounder. The effort is adjusted to the local ground conditions. Our Geotechnical engineers are at hand to review data and make site specific correlations between the monitoring data and requirements.
