Diagnosing subsidence or foundation movement through a simple present condition survey may sometimes prove difficult without further investigation.
The most common sign of foundation movement is cracking. As a foundation moves, the building will become distorted, particularly around openings in walls.
The construction type of the building can also have an influence on how the building will react to such movement. Foundation movement in this conservatory in Co. Cork has resulted in the window frames becoming so distorted that the glass has cracked!!!!
