Compaction is the process of reducing the volume of a material by
applying pressure, typically to increase its density and improve its
mechanical properties. This process is commonly used in
construction and civil engineering to enhance the stability and
load-bearing capacity of soils or materials.

Machines such as rollers and compactors are employed for
compacting surfaces like soil, asphalt, or concrete in various
spaces, including construction sites, roadways, and building foundations.
