Figure 5
Figure 9 shows some damage to the wall face caused by rotation of the facing
elements due to differential settlements. Up to 9 cm relative movement between
facing units was observed, as well as some cracks. From these figures it is clear
that some improvement of the foundation soil should also have been carried out
in this case in order to minimize the development of differential settlements.
