History
Wienerberger was founded in 1819 in Vienna by Alois Miesbach (1791–1857) and has traded since 1869 on the Vienna Stock Exchange. In 1986 the company expanded from a local Austrian brick-maker into one of the world’s largest producer of bricks within a few years.

The company has acquired a number of its competitors, including Baggeridge PLC in June 2007, with the takeover being cleared by the British Competition Commission in May 2007; and Keymer Tiles in 2014.
