ABSTRACT:
A system for forming an elongate concrete structure (20) which extends in a first direction and includes an outer surface (26) with a textured pattern having concave and convex portions which extend other than in just the first direction. The system includes an elongate, planar form (32) having a reverse image of the textured pattern on one side (202) thereof, a conventional slipformer (30), the mule (60) of which is modified so as to include only a top wall (64) and a side wall (62), with the opposite side wall of the mule being removed, and a side arm assembly (150) coupled to the slip former for supporting the form so that it engages the mule so as to block off the opening in the mule created by removal on the opposite side wall thereof. The planar form is erected prior to formation of the structure, remains standing during the formation of the structure and is dissassembled a predetermined period of time after the concrete structure has been formed. The side arm assembly slidingly engages the outer surface of the form as the slip former is moved in the first direction.
