Which method is considered the easiest for compaction?

Puddling or wetting the soil is viewed as an easy method for compaction because it involves introducing water to the soil, which can significantly increase its density by reducing air voids and allowing the soil particles to pack closer together. This method is particularly effective in certain soil types, such as clay, which can swell when wet and then compress when pressure is applied.

When water is added, it acts as a lubricant, enabling soil particles to move more freely and settle into a denser configuration. Moreover, wet soils are generally easier to manipulate and can achieve a good level of compaction without the need for heavy equipment. This simplicity makes it appealing, especially in smaller or less intensive construction projects.

Other methods such as rolling, vibratory compaction, and mechanical compaction typically require more specialized equipment or techniques, which can make them more complex and labor-intensive than the simple act of adding moisture to the soil. In comparison, while these other methods can achieve higher levels of compaction, they may not offer the same ease of application as the process of puddling.
