In the United States, permeable concrete is seen as one of the great marketing opportunities for the readymix industry.  In Europe we seem to have given it less attention.  However, the Finnish industry has taken some important steps, with an organised development programme.  This was reported recently in betoni magazine, and you can look at it here.  It is, of course, in Finnish, but there is an English summary at the end.  Again, the photographs are very informative, demonstrate the visual possibilities and, generally, give a good idea of what can be done with this type of paving.  We have translated the text for the photographs (thanks to Ari Mantila and Vesa Anttila) – click here.
