Soil compaction | UMN Extension

Soil compaction concerns have been growing in Minnesota as both annual precipitation and farm equipment size have dramatically increased. Wet soils are particularly susceptible to compaction. Heavy equipment and tillage implements amplify damage to the soil's structure, decreasing pore space and limiting soil and water volume even further.


compaction depends on the lift thickness, contact pressure, and soil moisture content. Most contractors get a feel for these figures, based on their local experience. If you are dealing with a contractor who has not previously worked in the area, you should be wary.

Dynamic Compaction - an overview | ScienceDirect Topics

Dynamic compaction (DDC, heavy tamping, dynamic consolidation, etc.) is a cost-effective method of soil compaction whereby a heavy weight is repeatedly lifted and dropped from a height, impacting the ground surface with a readily calculated impact energy (Figures 6.12 and 6.13).Costs are reportedly about 2/3 that of stone columns, with up to 50% savings over other deep densification ...

Soil compaction - Wikipedia

In geotechnical engineering, soil compaction is the process in which stress is applied to a soil causes densification as air is displaced from the pores between the soil grains. When stress is applied that causes densification due to water (or other liquid) being displaced from between the soil grains, then consolidation, not compaction, has occurred.

Safety Standards for Compaction Equipment

Whatever product and brand, safe operation of compaction equipment depends on its users. The first step in operational safety is always using the right tool for the job.
