WebMar 31, 2024 · Compaction of soil increases the shear strength and load bearing capacity of the soil. Compaction reduces the voids ratio making it more difficult for water to flow through (water seepage) 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 ...
