Is soil the new construction goldmine?

What if, to encourage more sustainable construction all we had to do was look under our feet? Excavated earth, the subsoil traditionally discarded as waste on building sites, turns out to be a valuable resource once we start thinking circularity. This innovative, ecological and economical construction solution deserves to be recognized.

Subsoil offers the construction industry a hybrid solution; not only does it help reduce our reliance on natural resources – like sand and aggregates – but it also holds natural properties that can contribute to building efficient and comfortable environments – thermal inertia, hygrometric regulation, heat storage capacity, to name a few. Think about it this way: we can build walls, and floors, that keep our spaces cool in the summer and warm in the winter, regulate humidity levels, and purify the air, all while achieving significant carbon reductions.
