Doka Group

Doka, undasch The Store Makers and undasch Industrial Solutions make up the Umdasch Group AG with its headquarters located in Amstetten, Austria. In 1868 Stefan Hopferwieser founded the company St. & A. Hopferwieser as a carpenter in the town of Kollmitzberg. During the first 80 years of the company, the company had diversified into carpentry, sawmill wood and metal manufacturing, producing among others furniture, home appliances, metal hardware and packaging. In 1949, the engineer Josef Umdasch, who was married to Mathilde Hopferwieser (granddaughter of Stefan Hopferwieser) became the managing director of the company rebuilding and restructuring it. Josef Umdasch had been a board member of the company since 1939. In the 1950s prefabricated formwork production and store fitting production arms of the company crystallized into the two modern branches within the corporate group. In 1961 the corporate group was renamed to Umdasch KG. After Josef Umdasch retired his children Hilde and Alfred Umdasch directed the company.

Doka

In 1958 the company branch Doka was founded. The company founding and company name are interlinked with their first product and projects. In Austria in the 1950s, large infrastructural construction was underway including several hydro electrical dams. The dams were being built on the Danube river (Donau) and its tributaries by the Austrian utility "Donaukraftwerke" or DOKW for short, translating as 'Danube power stations'. Because of the great size of these structures, traditional timber beam formwork was too labor-intensive to form the large walls. Thus a large scale systematic and reusable formwork was developed, with the wooden formwork panels being produced and shipped from the Amstetten company. Originally the DOKW was the delivery address, but then became the product name (DOKW boards). Linguistic usage slurred DOKW into DOKA, which became the name of the newly founded company.

In 1961 the first subsidiary was established in Germany, followed in 1977 by Brazil and Kuwait.

The formwork products, systems and design service include formwork panels, slab formwork, wall formwork, one-sided wall formwork, climbing formwork, tunnel formwork, dam formwork, bridge formwork (cast-in-place balanced cantilever bridge, concrete arch bridge and steel combination bridge formwork), shoring / falsework, tie systems and field support, software and training. The company is also a global supplier of scaffolding solutions for a varied spectrum of applications. Doka's business is based on a combination of production, equipment sale & rental, engineering and maintenance. Most of the formwork production takes place at Doka's central plant in Amstetten. The Doka three-ply sheets are made in the branch plant in Banská Bystrica in Slovakia. With the acquisition of MFE 2024, Doka also has production capabilities in the Southeast Asia region.

Another area of Doka's business is digital solutions aimed at increasing productivity in construction. At bauma 2025, the company presented Doka 360, an integrated platform that digitally maps all central stages of the formwork process – from planning and ordering to material management and returns.
