What Is Subsidence?
The Institute of Structural subsidence engineers defines subsidence as “the downward movement of a building and foundation caused by the loss of support of the site beneath the foundations.”
It’s important to note that Subsidence is typically DOWNWARD movement while Pyrite consists of upward heave movement.
The term itself is quite commonly known in the public domain and unfortunately can be the scary word applied to any type of subsidence cracking occurring to buildings.
The Insurance Industry common policy wording describes the Subsidence occurrence as an and is an insurable peril within typical household insurance policies.






What Causes Subsidence?
- Leaking Drains
- Leaking Water-Mains
- Shift of Water Table – seasonal or weather influenced
- Excessive run off water due to topographical changes of ground and infrastructure

What People Say About Banrach
Questions we regularly receive about Subsidence
Cracking in walls –
Some hairline cracks may be just a result of building settlement, particularly in newer buildings.
Cracks relating to subsidence should be either side of wall, and typically are:
- Diagonal cracks around doors & windows.
- Vertical cracks between building & extension.
- Horizontal cracking, increasing in width.
- Doors/windows sticking
- Uneven floors
- Building tilt
Most household insurance policies cover ‘subsidence’ to some degree.
We can review your policy for you to see what cover, if any, is in place.
Firstly, we will visit the site, to meet with you, inspect the property and establish whether or not we believe subsidence is present.
If we believe it is present, we will arrange a CCTV drain survey, and/or a Leak Detection survey. We will compile a report with our findings.
If you are happy for us to do, we will negotiate on your behalf with the Insurance Company/Loss Adjuster/Assessor.
To fix the problem, you will need to engage the services of a specialist engineer and a subsidence contractor.
The specialist engineer will survey the building, and design an engineering solution tailored to the issue.
The damage is usually remediated by pressure grouting under foundations, installing mini piles, or a combination of these.
The cracking may be not be as a result of subsidence.
Fine, hairline cracks are usually not subsidence related. These can be related to concrete shrinkage.
We can discuss options with you on site to remediate the cracks.
