Wall method used to form buttressed columns.
WALLS
There are several ways to construct cast-in-place concrete walls using lightweight fabric formworks. The most developed cast-in-place wall formwork systems have been invented and developed by the Japanese architect Kenzo Unno. His work in this area is described in the PDF article “Kenzo Unno – Fabric-formed Walls” (see Resources below).
CAST research has concentrated on developing cast-in-place walls using modified standard plywood wall formworks lined with geotextile fabric form-liners. We call this the “Bulge-Wall” system because these walls are formed by allowing the fabric liners to deflect outwards though gaps or holes cut in the plywood panels, or to deflect inwards by pushing the fabric into the volume of the wall. The bulge wall system was specifically developed to allow builders familiar with conventional formwork construction to easily and confidently adapt to this fabric forming technique. Any builder used to placing drainage fabric form-liners in a plywood wall forms will have the tools and knowledge required to form Bulge-Wall constructions. This same system can also be used to form a variety of unique columns, and buttressed columns.
