Measuring the differential movements of a building’s foundation

Using a laser levelThe laser level is a device for measuring the differential levels of a building or structure., this technique allows us to measure the differential movements of a building’s foundation, for example, the degree of subsidence, which may affect the foundation. The laser level is thus essential in determining whether a building needs to be stabilized with postsPosts are used to stabilize and improve a building foundation, in order to prevent subsidence. This technique is called posting..
