ABSTRACT:
An improved wood substitute product (56) is provided having sawability and fastener-holding properties which approximate natural wood. The product (56) includes an outermost casing (20) preformed to a desired shape and filled with a cementitious fill material (55) including respective amounts of cement and synthetic resin foam. In fabrication procedures, the casing (20) is first formed as a hollow tubular body by roll forming, rotational molding or similar techniques, whereupon the body is temporarily capped and filled with the material (55). A filling device (28) is preferably employed for this purpose, which includes a pumping assembly (32) as well as an elongated horn (30), which is complemental with the casing (20).
