A soil compactor is a construction equipment that uses force to compress and densify soil to improve its stability and load-bearing capacity. It is commonly used in construction projects, such as road works and residential construction, to create a solid foundation for the structure being built. Soil compaction occurs when soil particles are pressed together, reducing pore space between them (Figure 1). Heavily compacted soils contain few large pores, less total pore volume and, consequently, a greater density. A compacted soil has a reduced rate of both water infiltration and drainage.A compactor machine is a device that applies downward pressure on dirt, soil or gravel to compress the ground and fill in air pockets. After using a soil compactor, the floor can sustain heavier weight on an even surface, allowing construction teams to roll out heavier machines with fewer safety hazards.
