Practice shows that the most frequent cause of the so frequent settlements in foundations (indirectly leading to the appearance of cracks) is the foundation in "weak" soils. Changing groundwater levels in these activate the processes of swelling and compaction causing cyclic movements in the foundations. Changing the water content of soils changes their consistency and mechanical performance.

Therefore, lowering the water table by building slabs and paths around the house, drainage systems and draining roof water away from the foundations are sometimes sufficient measures to stabilise the foundations.

In cases where these measures have been implemented but settlement of the foundations and cracking of the supporting structure persists, a geological survey or a cheaper option of a GPR survey is mandatory. The GPR survey can also be done at the inception stage, which generally saves considerable money on unnecessary drainage works as well as time for the owners. The GPR data unambiguously shows the presence, volume and location of groundwater and the most optimal measures to solve the problem.

Another common cause of subsidence is failures in the water or sewer systems in the vicinity of
