northern californian-based watershed materials co-founder david easton is applying strategies learned from constructing natural and sustainable buildings into making unitized blocks. made from regionally sourced, recycled aggregate, the pieces can be mass produced and display the richness of local mineralogy. they replace carbon intensive concrete versions, which are typically very energy intensive to make due to the binding ingredient of cement – a giant emitter of co2. limestone, another key element is heated to 1,500 degrees celsius, also consuming a tremendous amount of fuel. watershed’s masonry blocks focus on several levels of sustainability – post-industrial recycled material is included instead of crushed virgin aggregate and half the cement is added while retaining structural integrity. developed with the support from the national science foundation, the manufacturing process aims to achieve a zero cement structural building block with recycled, post-industrial content.

 


the blocks can be used as both structure and finish – no exterior cladding is needed for the wall
