A lot of the soil of Bangladesh is made up of alluvial Holocene deposit, which types by means of levels of soppy clay or free sand. For that reason, developing foundations for buildings or other structures in our region is high-priced. In these kinds of soft soil, footing-form foundations usually are not appropriate.
