Vertical drains and prefabricated drains. The main purpose of drains is to provide pore water with an escape path when the soil is subject to stressing due to preloading fill. Consolidation settlement takes place when pore water is removed from saturated soils. It is thus, as a rule, not necessary to install vertical drains if there is no water
