Do you know what subsidence is?Cracked Wall

When thinking of damage that can happen to your property you most likely think of a fire or flood but what about subsidence?

If you are a property owner you most likely know all about the possible damage that fire and flooding can inflict. However, subsidence is not a sudden event and not many people have information about it. In this article, I’m going to talk about the dangers of subsidence and some information about causes.

To begin subsidence is defined as the shift of a property due to defects in the foundation characterised as a downwards shift. Now when hearing that small description it may not sound serious but any shift and change in foundations can cause substantial damage.

Subsidence Damage

The damage subsidence can create include loss of structural integrity, cracked walls, ceilings and flooring. Subsidence is more complicated to solve then simple fire damage as the removed materials cannot be easily replaced. The affected material is the foundation of the property which removing would severely damage the property.

Subsidence occurs due to faults in the foundation, these faults include poor construction/materials as well as shallow foundations. These foundations provide inadequate support for the property. Shallow foundations are usually a result of older construction dates due to the standard of buildings being improved over the last 30 years requiring deeper stronger foundations as well as stronger more durable materials being used during construction.

A thick crack caused by subsidenceAnother cause that is commonly overlooked is tree proximity to the property. The roots of trees burrow in many directions around the base of the tree. If these roots come into contact with your foundation it can embed itself and weaken the structural integrity. The type of tree is also vital as some trees utilise thicker roots as they require more nutrients.

A lot of the information in this article I sourced from one very useful page I would recommend checking it out for additional information (and worded more professionally). The website is Also, check out their subsidence signs page to help you spot any damage.
