Subsidence is downward movement of the ground supporting the building, most commonly caused by:

  • the shrinkage of clay subsoil following long spells of dry weather trees and other vegetation which extract moisture from the soil causing it to shrink
  • leaking drains, which wash away the subsoil below foundations
  • mining activity
