Why is Underpinning So Important?

Solid foundations are essential when constructing any building or structure, but if these foundations need extra strength or stability, a process of underpinning may be necessary.

Underpinning involves excavating soil from beneath existing foundations and replacing it with a stronger material such as concrete or structural resin to strengthen the structure. Underpinning may be necessary for a number of reasons, including poor soil quality, a weak foundation or if additional building storeys are being added.

Underpinning is often a vital part of the construction process, so if you want to know more about why it’s so important, see our guide below.

Structural stability

Underpinning is used to improve the structural integrity of a building in cases where the original foundation is not strong enough. The foundation may have been weak to start with or shifted due to poor soil quality or the passing of time, but either way, underpinning can increase the strength and stability of a building and prevent further damage from occurring.


Weak foundations can lead to damage like cracks in walls and even cause floors to raise up. These structural issues can be very dangerous and run the risk of a building being unsafe for habitation or collapsing altogether. Proper underpinning is vital to ensure the safety of a building and ensuring it’s fit to live or work in.

Increased property value

Even if you have no plans to sell your property in the near future, weak foundations and structural issues like wall cracks can drastically reduce a building’s value. Resolve these problems early with underpinning and secure the future value and kerb appeal of your property.
