The architectural concrete surface is the area of concrete that remains unconcealed after completion that shows the characteristics of the design and manufacture (e.g. form, texture, colour, formlining, joints) and which plays a decisive role in determining the architectural impression of a structural component or structure. A wide range of architectural concrete surfaces can be achieved ...
