Soft soil refers to ground that is loose and not very compacted, making it less stable than harder types of soil. This type of soil often contains a high amount of water, which can further reduce its strength. Soft soil can be found in areas like marshes, riverbanks, and coastal regions, where the ground is often saturated. Construction on soft soil can be challenging because it may not support heavy structures well. Engineers often need to use special techniques, such as deep foundations or soil stabilization, to ensure that buildings and other structures remain safe and secure on this type of ground.
