Dynamic compaction is a construction process that permits to densify the soils by dropping on the ground a 10 to 30 ton weight repetitively from a height between 10 to 30 m over a preselected grid pattern using a specially adapted crane. The size of the weight, its impact area, the drop height, the compaction grid and the number of drops are all factors contributing to the success of a dynamic compaction project. Depths of improvement can be as high as 12 metres depending on soil conditions and type of equipment used.

Geocompaction's personnel have been involved in over 300 dynamic compaction projects over the last 17 years on a performance specifications basis. By both designing and executing the compaction plans, Geocompaction has the expertise to tackle the most difficult projects.
