Factors Influencing Swelling and Shrinking in Soils

WebThe type, amount, and mineralogy of colloids will strongly influence most land management decisions. For example a soil that is 40% of clay that primarily consists of smectite (a 2:1 shrink-swell clay) could have limitations for constructing roads, or building foundations due to the shifting of the soil as the soil wets and dries.

WebSwell - Shrink Behavior The swell - shrink potential of expansive soils is determined by its initial water content; void ratio; internal structure and vertical stresses, as well as the type and amount of clay minerals in the soil. Swelling pressures can cause heaving, or lifting, of structures whilst shrinkage can cause differential settlement. WebFor example, on the West Coast of the South Island, there could be soils that laboratory tests classify as shrink-swell soils but it is very unlikely that they would cause either swelling or …
