DYNAMIC SOIL COMPACTION Dynamic soil compaction (also called dynamic compaction) is a method used to strengthen loose or weak soils by dropping a heavy weight repeatedly on the ground surface. The force from these impacts compacts the soil particles, making the ground stronger and more stable. HOW IT WORKS A heavy steel weight — often between 10 to 40 tons — is lifted by a crane and dropped from a height of about 10 to 30 meters. When it hits the ground, the impact energy travels through the soi
