Using a simple sand additive process on a straight, parallel paths, with a fixed pouring height and varying speeds, we were able to achieve a whole spectrum of spatial inter-relationships on the surface of the sand. These were sprayed with latex to achieve surface rigidity and then used as a mold for concrete. Hills and valleys now become ribs whose exact dimensions and spatial placement is governed by strict structural and functional requirements for a retaining wall, conceptually a part of public Rhine river promenade in Basel. Changing soil configuration, ground water level as well as varying tieback height produces different material placement in the wall and therefore different structural reading. The wall becomes a window to the landscape behind.

DESCRIPTION

PROCEDURAL WALL

 

Sand casting is a manufacturing method several millennia old which could today provide a sustainable alternative for non-standard concrete molds. Its availability and easiness to process lends itself well to the highly controlled robotic manufacturing processes.
