What is the minimum size for a plate tamper used on pavers 3-1/8" and thicker?

The minimum size for a plate tamper used on pavers that are 3-1/8 inches thick is indeed 4,000 pounds. This weight ensures that the compaction force is sufficient to properly set the pavers into the base material, creating a stable and durable surface. When installing thicker pavers, achieving the correct level of compaction is crucial to prevent settling and shifting over time.

Tamper weights that are too light may not deliver the necessary force to compact the base effectively, potentially leading to issues such as uneven surfaces or paver displacement. The 4,000-pound requirement strikes a balance that accommodates the thicker material's density and ensures optimal installation performance. Thus, choosing a plate tamper that meets or exceeds this weight aligns with industry standards for proper compaction techniques in landscaping and construction.
