About us
Betonwerk Pfullendorf GmbH & Co. KG is a medium-sized ready-mix concrete company supplying the construction industry around the Lake Constance region with concrete and special concrete. In stationary concrete mixing plants, the company produces ready-mix concrete, lightweight concrete, heavyweight concrete, high-strength concrete up to C100/115, fibre-reinforced concrete, coloured concrete, bored pile concrete, thermal and fill concrete, flowable concrete and flowing screed, masonry mortar, special mixes as well as recycled concretes according to EN 206-1 / DIN 1045-2, and delivers them to the construction site on schedule with a truck mixer fleet. In addition, the company supplies gravel, crushed stone, sand, mixtures, chippings and natural stone, and accepts uncontaminated excavated soil for recovery. The offering is complemented by placing boom pumps (pumping height up to 46 m), mobile city concrete pumps (delivery up to 250 m), concrete conveyor belts, an in-house building materials laboratory as well as site monitoring according to monitoring class 2. Fields of application are residential construction, industrial construction, civil engineering, agricultural construction as well as structural engineering and renovation of existing buildings. The company operates its own plants in Pfullendorf, Salem and Ostrach and is represented via affiliated companies in Friedrichshafen, Kressbronn, Konstanz and Stockach-Hardt.
