What does compaction in site preparation refer to?

Compaction in site preparation refers to the process of increasing soil density. This is achieved by applying pressure to the soil, which reduces the volume of air in the soil pores, thereby making the soil denser and more stable. Increased soil density is crucial for various construction and landscaping purposes, as it helps to improve load-bearing capacity and minimize settlement issues.

By compacting the soil, one enhances its strength and stability, which is essential for the construction of structures, pavements, and roadways. A well-compacted surface also reduces the likelihood of erosion and can improve water management on the site by decreasing the permeability of the soil.

In contrast, reducing soil density, removing soil layers, or adding organic material would not achieve the intended purpose of compaction, which is focused on enhancing the strength and load-bearing aspects of the soil. Therefore, the action of increasing soil density is vital for effective site preparation and supports the long-term durability and performance of the construction project.
