The impact method of compaction is a dynamic soil compaction technique that involves dropping a heavy weight from a predetermined height onto the soil surface. This repeated dropping action creates high-intensity compaction waves that densify the soil layers. Often employed for larger construction sites and in preparations for foundations, the impact method is effective in compacting a variety of soil types, especially those that are more resistant to static compaction methods. The key advantage of this method is its ability to achieve deeper and more uniform soil compaction compared to traditional rolling or kneading methods, making it suitable for ensuring the stability and weight capacity of the foundation soil.
