Peat soils can be found in many countries around the world; 2,000km² through Hokkaido, whereas in Sri Lanka 5% to 10% of land area is covered by peat soil. The process of urbanization has created the need to utilize those areas in construction. However, construction over peaty soils always create special problems due to their poor engineering properties. Low shear strength is a major problem often causing stability problems in peat soils. In order to prevent such failures, peat ground should be improved using appropriate techniques.
