This article focuses on fabric formworks for use in forming concrete members used in architectural works but it should be kept in mind that this versatile means of containing concrete saw some of its first use in civil engineering works such as erosion control. Concrete members for architectural works have traditionally been cast using a rigid formwork in some desired arrangement ever since men first sought to contain early forms of mortar and “concrete” in their structures. And given the need for a mortar or concrete to set and cure properly the use of a flexible formwork might appear to be rather ill-suited for casting any concrete member. But, this method of casting concrete may in fact be used nearly anywhere a rigid formwork is used and is beginning to attract attention as a method of forming concrete members now that strong and inexpensive geotextiles have become available. This article will hopefully pique the reader’s interest and leave her/him inspired to think beyond the simple prismatic shape through the use of fabric as a formwork for the construction of concrete members.
