2021219 • Compaction reduces the voids ratio making it more difficult for water to flow through soil. This is important if the soil is being used to retain water such as would be required for an earth dam. • Compaction can prevent the build up of large water pressures that cause soil to liquefy during earthquakes. 3.2 Factors affecting Compaction
