Method for the determination of settlement in foundation structures for buildings such as dams using a long length of tubing installed within the foundation structure in which mercury and water with a defined interface is forced along the tube from one end against a constant back pressure applied at the other end, the quantity of mercury displaced along the tube being measured together with the pressure applied to compute the position of the interface in the tube and the height thereof above a datum point. A construction of unit to provide the constant back pressure is also disclosed in the specification.
