A distinction should be made between compaction techniques for new land and consolidation techniques for loose soil. Compaction is used for coarse-grain soil (sand) and can be done with smooth rollers, HEIC, or dynamic impact or rapid impact compactors or vibroflotation. When the soil is too fine, or too silty, replacement methods are used. These can be sand poles, grind poles and mixing with cement or other suitable materials that render the soil almost immediately ready for use. Other techniques are used exclusively for expediting consolidation of loose soils. These include vertical drains, sand drains and a system known variously as BeauDrain, IFCO or PTD, as well as vacuum consolidation, all methods in which soil improvement takes a longer period of time.
