I have just received an environmental report for a property I am hoping to buy, which flagged up increased risk of subsidence. This is due to clay in the soil - which expands/contracts depending on temperature and water content.
This is very common in south of the UK, and usually doesn't have too much risk involved (especially if the foundations were built under soil considerations) but I wonder what impact this might have in the close future, with temperatures soaring and so many old buildings/homes over 100 years old.
Climate change will impact on things that don’t even cross our minds.
- mschuster91 7y agoIt may very well happen that the same thing happens now with the top soil as with groundwater - once the water is gone and the ground is dry, the weight of everything above it will settle down and compress the lowest parts of the ground - rinse and repeat and you suddenly have soil which is not capable of storing or even buffering water, which means a massive risk increase for flash floods at one side and a lack of drinking water on the other side.

- mariushn 7y agoMay I please get that report as a sample? I'm looking into how to make easier to produce such reports. My email is in profile. Thanks!
- joaodlf 7y agoHi, I can't really share the report itself (way too much of my own data in it), but the section on subsidence risk comes directly from this: http://mapapps.bgs.ac.uk/geologyofbritain3d/index.html http://mapapps.bgs.ac.uk/geologyofbritain3d/index.html
