In exterior or interior applications, cast-in-place concrete can now reproduce the look of slate, cobblestone, brick, tile, limestone, travertine, polished marble, and even wood. And decorative concrete is equally at home on flatwork or vertical surfaces. The finished products are stunningly attractive and, compared to the masonry finishes they usually mimic, economical. Contractors have been able to achieve these superior results thanks to the introduction of a variety of new tools, products, and techniques.
