Compaction Equipment and Methods: Compaction of …

When compacting clay soils, you would want to use a rammer or a vibrating Sheepsfoot as they provide excellent compaction for clay soil. A rammer is good for small and tight access areas, especially for small trenches for walls. Whereas a vibrating Sheepsfoot is best for larger areas. Both of these action provide an impact method of compaction.
