What is Subsidence?

Subsidence happens when a house is slowly sinking or collapses into the ground. In doing so some of your building’s foundations may go with it. Putting a direct strain on your buildings structure. This can be a very serious issue; it can affect the structure of your property but also can affect on the selling value of your property.

Some of the factors the can cause subsidence are:
  • The type of soil you have. Clay like soil can shrink and crack especially in hot and dry weather. This makes the ground unstable and potentially causes the foundations of your building to sink. If you live in an area prone to droughts you are much more likely to suffer from subsidence.
  • Trees and shrubs can also cause subsidence. Especially if they are close to the foundations of the building. Trees and shubs also require water to grow meaning your soil will be much drier. In turn this can cause issues.
  • If you own a older building you may have the foundations themselves to deal with. With older homes being more likely to have shallower foundations.
  • In some areas of the UK local mining activity can play a major part in causing subsidence. Former Quarrys and pit sights can also cause issues.
  • If you have a leaking drain or water main this can soften and wash away and soil. Causing remaining soil to be compacted under the weight of your building.
