Plate Compactors and Rammers: Making a Choice Before the Concrete Pour

The most important factor in making that choice is the type of soil to be compacted. A rammer, which uses a piston set and springs to generate force, works best on cohesive soils, which are composed of clay and silts. Vibratory plates, on the other hand, are low-amplitude, high-frequency machines. They are most effective compacting granular soils, which are made up of sand and gravel.When raw soil or aggregate needs to be compacted before a pour, what do decorative concrete contractors use to pound the ground? Rollers are too much machine for smaller jobs. So generally, the choice is between rammers and vibratory plate compactors.
