Leca Stones
The fan shaped conference center has a foundation of porous concrete called Leca. The porosity makes the material heat insulating, strong and frost-proof – as well as lightweight. The porosity minimises material use for the foundation, compared to more traditional materials. Leca is an inorganic material and cannot be destroyed by rot, fungus or insects.
Who’s behind it:
Weber, Saint-Gobain
Where you’ll find it:
