Solubility is the main problem of gypseous soils. In dry state, these soils are resistant and have good engineering properties. However, when saturated by rainwater or rising groundwater table, the minerals in these soils are washed out, making...

,Gypseous soils are considered problematic when used as the foundation in civil engineering structures such as roads, buildings and dams, due to their solubility. These soils are resistant and have good engineering properties in their dry state...
