Interesting work has been done, especially in England, to achieve patterned concrete surfaces with job placed concrete. The technique consists of lining formwork with rubber sheeting of the desired pattern and texture and placing and vibrating the concrete against the sheeting to cast its pattern into the surface of the structure. The sheeting may be glued to the forms or fastened by means of clips. British experimenters say that the use of linings creates no special problems in concreting operations. Moreover, they agree that the production of a finished textured surface in one operation results in a definite cost saving when compared with the creation of similar effects by other methods, such as tooling, exposing the aggregate, or gunning.
