ABSTRACT:
A composite burial vault is provided having a hollow liner constructed of a synthetic plastic material which is filled with concrete. In constructing the burial vault, a liquid bonding agent is applied against the liner. The bonding agent can be either an adhesive or a solvent which acts upon the plastic material or a combination of the adhesive and the solvent. Before the bonding agent dries, aggregate is applied to the surface of the liner preferably by a flocking gun. Alternatively, the bonding agent and aggregate can be simultaneously sprayed against the liner. As the bonding agent dries, the aggregate is bonded to the liner either by the adhesive and/or by a portion of the aggregate partially embedding in the liner. 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. Reinforcement strips are provided to strengthen the corner edges of the liner. Preferably, the aggregate is sufficiently small so as to permit stacking of the treated liners and, in one form of the invention, stacking notches are provided around the upper corners of the liner to facilitate stacking the liners upon each other.
