ABSTRACT:
A flexible form is presented. The flexible form may be shaped to produce the desired contour of concrete or other plastic material in the construction of various structures and is held in place by a plurality of positioning brackets. The flexible form is made of two or more parts, an outer part which provides durability and wear resistance and an inner part which provides the desired flexibility and is protected by the outer part. The parts are assembled in such a manner that each flexes independently of the other parts.
