ABSTRACT:
A composite burial vault is provided having a hollow liner constructed of a synthetic plastic resinous material which is filled with concrete. In constructing the burial vault, the liner is constructed from thermosetting resinous material in any conventional method. While the liner is still wet, aggregate is applied to the surface of the liner by a flocking gun or the like. Concrete is then poured between a mold and the treated surface of the liner where it forms a mechanical bond to the coarse aggregate coating on the liner.
