Before choosing a compactor, you must know what soil type you will be compacting. Les plaques de compactage fonctionnent mieux sur les sols granulaires tels que le gravier, le sable ou l’asphalte léger. If you are working with soil with clay or silt content, a compactor with higher-impact force will be more productive because those materials are not easily compacted with vibration. Even if you use a compactor with high-impact force for your site, you can experiment with lift thickness to ensure good compaction without cracking.

Vibratory plate compactors are ideal for granular soils such as gravel, sand, stone, dust and 2A aggregates (sandy gravel). Leurs vibrations déplacent les particules du sol ensemble pour un compactage très dense. They can also compact soil with some clay content or asphalt, perfect for finishing the top layer of backfilled trenches. However, a roller or jumping jack rammer compactor would be a better fit for deep compacting if you are working with a high-clay or high-silt content material.

Jumping jack rammer compactors are narrower, and they have increased impact force. They are ideal for high-clay or high-silt (cohesive) soils and high-moisture soil. The rammer compactor is best if you need to compact the material in a narrow trench or around utility pipes. The plate compactor is the right choice if you need to compact a large, flat area with granular soil. Instead of relying on impact force, the plate compactor vibrates, moving the soil particles closer together, resulting in high-density compaction. Cependant, la pilonneuse et la plaque de compactage vont de pair : Use the plate compactor to prep the area, the jumping jack to compact the cohesive soil and the plate compactor to finish.
