A plate compactor and a tamping rammer (often called a jumping jack) both compact soil, but they suit different jobs. In short: choose a plate compactor for open, flat areas of gravel, crushed rock and paving base, and a tamping rammer for narrow trenches, footings, backfill and cohesive soils such as clay.
Quick comparison
| Plate compactor | Tamping rammer | |
|---|---|---|
| Best for | Driveways, paving bases, paths, gravel | Trenches, footings, backfill, fence posts |
| Works best on | Granular material (gravel, crushed rock, sand) | Cohesive soil (clay) and mixed soils |
| Coverage | Wide plate, covers open areas faster | Small shoe, ideal for tight spaces |

Frequently asked questions
Can a plate compactor be used in a trench?
Only if the trench is wide enough for the plate. For narrow trenches a tamping rammer is the practical choice.
Which is better for clay?
A tamping rammer concentrates impact through a small shoe, which suits cohesive soils like clay.
What do I need for a paving base?
A plate compactor. Compact the base in layers and follow the paver manufacturer's guidance. A water tank model, such as the Kane KAU90, helps when working with asphalt.
