Dynamic Compaction: Uses a heavy weight dropped from a height to densify soil. Effective for granular soils.
Vibrocompaction: Uses vibration to rearrange soil particles and increase density. Suitable for granular soils.
Roller Compaction: Employs heavy rollers to compact soil in road construction and embankments.
Cement Grouting: Injects a cementitious mixture into the ground to fill voids and improve soil strength. Used for stabilization and foundation improvement.
Chemical Grouting: Uses chemicals (e.g., polyurethane, silicates) that react and harden in the soil to increase strength and reduce permeability.
