Maintaining the aesthetics of a building
is about protecting its value.

In 2004, at a time when the trend was shifting toward renovation rather than new construction, we started our business by developing products that were conscious of the aesthetic value of concrete and other materials. The area we have constructed to date exceeds 1,000,000㎥.
