We define subsidence as downward movement of the ground supporting the building. In the UK and heatwaves and higher temperatures make homes more susceptible to the risk of subsidence as a drier soil results in clay shrinkage.
What can cause it?
- Clay soil shrinking following long spells of dry weather.
- Trees and other vegetation taking moisture from the soil causing it to shrink.
- Leaking drains, which wash away the subsoil below your foundations.
- Mining activity.
