Plates work by vibrating a wide footprint across the surface; a \u003cstrong\u003erammer\u003c\/strong\u003e works by hammering a narrow shoe straight down, which is what actually compacts cohesive soil — clay, silt, mixed backfill — in the confined space around a pipe or against a foundation wall.
