Now-a-days engineers bring artness to concrete applying different finishing techniques. Prefabricated panels of concrete either for wall or slab, even for roofing are used successfully, having excellent finishing and esthetic effects.

Now we can produce textured concrete of having finishing like board marks, many types of lining can be provided with special techniques. These developments of finishing replace the costly veneering to hide concrete.
