The brothers Rudolf and Konrad Adler founded the gravel works in Edling in 1956: the company Gebr. The first ready-mixed concrete plant was built in 1969 and expanded in 1983 when the second generation, Peter and Rudolf Adler Jun. joined the company with a second large mixing tower. The gravel and ready-mix concrete plants form the basis of the company's business. After several trial phases, the company entered the production of precast concrete elements in 1999 with "diArco® vault systems" and the construction of an office and show house with a classic four-column room. Successful orders led to the construction of the company's own production hall in the summer of 2000.
