A process for providing a corrosion resistant synthetic plastic resin coating on a surface of a concrete structure comprises cleaning the surface of the concrete structure, forming a fiber containing sprayed concrete layer having a plurality of fiber components therein, for example glass fibers or plastic fibers, on the surface of the concrete, and subsequently applying a synthetic plastic resin thereto, whereby the fiber components projecting from the fiber containing sprayed concrete layer act to anchor the synthetic plastic resin to form the corrosion resistant coating. The corrosion resistant synthetic plastic resin coating preferably contains a polyester resin, and a polymer-cement-concrete base layer may be used to help bond the fiber containing sprayed concrete layer to the cleaned concrete surface.
A process for providing a corrosion resistant synthetic resin coating on an internal surface of a concrete structure in the form of a waste tank or conduit, which comprises the steps of:

A process for providing a corrosion resistant synthetic resin coating on an internal surface of a concrete structure in the form of a waste tank or conduit, which comprises the steps of:
A concrete structure in the form of a tank conduit internally coated with a corrosion resistant synthetic plastic resin coating for a concrete structure comprises a fiber-containing sprayed concrete layer provided as an intermediate layer on said concrete structure, said fiber containing sprayed concrete layer having a plurality of fiber components mixed and distributed therein and projecting therefrom and a corrosion resistant synthetic resin layer above said fiber-containing sprayed concrete layer anchored on said fiber components.
