We came across the following snippet on LinkedIn recently and thought it a useful reminder that when assessing ground risk you need to do more than just commission an Envirocheck Report or similar….
“Did you know that many of London’s rivers have been ‘lost’? This can be rather important if you are building a basement. The rivers Fleet, Tyburn, and Westbourne, to name but a few, historically ran through London to the Thames. Many were replaced by combined sewers in the late 19th Century and are no longer seen at surface.”
The river flowing through a basement is quite amusing, especially the fish that seem to be visible! For more details follow this link to the original article.
