In order to expansive soil to cause foundation problems, there must be fluctuations in the amount of moisture contained in the foundation soils. if the moisture content of the foundation soils can be stabilized, foundation problems can often be avoided. i will be following up on this concept a bit later. ii. cause of expansion soils are composed of a variety of materials, most of which do not d. test pit 4 (main building) the rc strip foundation has width of 190 cm and thickness of 30 cm. depth of foundation is 210 cm from the adjacent internal ground level.
