ABSTRACT:
A concrete structure, such as a burial vault, having an integrally bonded thermoplastic resin liner. The liner is a rigid molded product having a bottom wall and side walls and an open top. A thermosetting resin adhesive is applied to the outer surface of the liner and consists of an epoxy resin system, a solvent for the thermoplastic liner, and a surfactant. Before the adhesive is fully cured, wet flowable concrete is applied to the adhesive layer. The solvent acts to solubilize the outer surface of the plastic liner, while the surfactant reduces the hydrophobic characteristics of the adhesive to provide a firmly bonded composite structure.
