ABSTRACT:
A method for forming an elongated concrete structure (20) which extends in a first direction and includes at least one outer surface (26) with a textured pattern having concave and convex portions which extend other than in just the first direction. The system comprises one or two elongated planar forms (32 or 32a/32b) having a reverse image of a textured pattern on one side (202) thereof, a conventional slip former (30), and a side arm assembly (150) coupled to the slip former for supporting the one form(s). The form(s) is erected prior to formation of the structure, remains standing during formation of the structure, and is disassembled a predetermined period of time after the concrete structure has been formed. The side arm assembly (150) slidingly engages the outer surface of the form(s) as the slip former (30) is moved in the first direction.
