Building Failure and Subsidence Investigation
What is subsidence and heave damage?
Subsidence and heave damage occurs when differential movement in the ground causes movement of the building foundations. The damage often shows up as cracks in the walls or ceilings of a building, and often found around door or window openings.
What causes this?
Subsidence most commonly occurs when clay soil under the foundations dries up and shrinks, frequently due to moisture extraction by the roots of nearby trees. This type of subsidence typically occurs in the Summer following hot, dry weather. The second most common cause is leakage from underground pipes washing away or softening the soil beneath the foundations. Buildings can also move and be damaged by other factors including the movement of old coal, flint and chalk mine workings and the collapse of shafts; natural features such as sinkholes; infilled quarries; soft soil and unstable slopes. Alternatively, heave is the expansion in clay soil which most commonly occurs as a result of rehydration following the removal of trees. This causes differential upward movement of foundations.
