Cofra - Model CDC - Compaction System- Brochure

Due to the increased scale of dredging equipment, dredged material is often deposited on sites at a much greater rate than was the case 10 years ago. As a result, there is less time to compact the sand in thin layers and, the compaction is forced to take place over thicker layers. Few compaction techniques with a high production rate and a reasonable price are available for these thicknesses. With the development of the CDC technique, Cofra has provided this niche market with a promising technique that compacts the subsoil homogenously and accurately. Depending upon the soil type and the energy input, compaction of the subsoil can be achieved to a depth of approximately 9 metres below the surface.
