London is a particular hotspot for subsidence. A large number of properties in the Greater London area are built on London Clay, which is one of the most shrinkable of soil types as it’s highly susceptible to changes in volume caused by variation in water content1. This is reflected in the deformation of ground by...

Of course, Cornwall is not the only county to be affected by mining, in fact there are around 172,000 recorded coal mine entries, but over 2 million non-coal mine shafts...
Provide peace of mind with a Mining Risk Assessment from our in-house mining subsidence experts.
The St. Austell area in Cornwall is famous for its association with china clay where rich deposits of Kaolin have been mined over the centuries. The mines have been so ingrained into the Cornish economy that pretty much everybody in the local area either worked for companies involved in the china clay industry or had...
The maps plans and charts that the specialists at Mining Searches UK (MSUK) consider for mining risk assessments vary widely and can include written documents, plans and sections of underground workings and surface plans, even plans jotted down back of a cigarette packet style. As a result, the information shown on the plans is viewed...
