UK Subsidence Maps

UK subsidence map

Subsidence is a common problem in the UK, due to the soil types we have in England and Wales. It is an issue that affects thousands of households and businesses. However, certain areas are more susceptible than others to subsidence.

We created a subsidence map of the UK, as well as more focussed regional maps, to understand where the problem areas are. This means that we can focus on refining our solutions according to the geographic soil types we’re dealing with. Since we find these maps so useful we thought that you might, too, so we’ve made them available to download as PDFs.

Subsidence risk area maps

We’ve taken around 10,000 individual data sets and qualified them to produce a complete UK map and more detailed regional views. As you can see, the areas which suffer the most are the big cities, like London, Birmingham and Manchester. Reasons for this include increased weight and pressure on the ground due to lots of buildings and skyscrapers in a condensed area, and ground water in the area being used up, causing soil to dry out and compact.

Soil types that are prone to subsidence

Subsidence can happen anywhere, but some areas are more susceptible due to the soil type. These include clay, silt, sand and gravel soils.

Clay and silt are ‘cohesive’ soils, which means that their volume will vary depending on their moisture content – they’ll swell when wet and shrink when dry. 75% of UK ground subsidence cases are caused by soil shrinkage, so if you live in an area of cohesive soil then you are more likely to be at risk. With the recent speight of hot weather we’ve had this year, these soil types have been even more susceptible to contraction.

Sand and gravel are ‘non-cohesive’ soils, which means that they don’t vary in size depending on moisture content. However, they are susceptible to being washed away by water flow. This means properties in areas with this soil type can be at risk during wet periods of heavy rain or flooding, or if they are located near a body of water.

Is your property at risk?

If you are worried about your property suffering from ground subsidence, then take a look at the map to see if you are in one of the areas that is most at risk. We may be able to produce specific maps on request too, so please email if you are interested in a map of a specific area.

If you believe your property is experiencing ground subsidence, then get in touch with the team and we’ll see how we can help you with our innovative subsidence solutions.
