Founded by master engraver Johannes Dallmer, Sr, the company was originally committed to the production of stamps, imprints, and fine engraving work on lights. The decisive step occurred in 1963 when sanitation technology became the central business area.
Dallmer now has around 230 employees and has developed itself as a successful drainage specialist. More than ever, our family business stands for innovation and is developing itself into a brand for architects through its high-quality design.
In recent years, we have invested more than 10 million euros in the future of our company, in order to ensure all-round growth and further development. We have developed planning and action strategies that are fit for purpose, not only in the present, but also in the future.
The building complex which was extended in 2019, provides more production and office space.
Dallmer products remain very much in demand; above all the increasing popularity of the level-access shower has pushed the sales figures up. For us this means: we need more machines, more employees and it is thus time for another new build – this one will be annex no. 5. The new building provides 500 m2 of production space on the ground floor and 700 m2 of office space on the upper floor, where part of the administration is housed. The employees here enjoy modern architecture which uses generous glazing and open design to create a transparent atmosphere and encourage communication.
Planning for tomorrow today.
Dallmer has acquired three machines for its metal production; two milling machines and a water-jet cutter The machines will be operated by five new employees who were hired specifically for this purpose.
Due to the sharp rise in demand, Dallmer is expanding its premises: we have bought an adjacent 20,000 m2 piece of land for the purpose of building a new shipping and logistics centre. This will give Dallmer an additional 4,000 m2 hall space with a 50 m long bridge connecting the old and new hall.
A lot has happened in the last 100 years: we have completely changed our core business, given design the level of priority it deserves and revolutionised the drainage of level-access showers. And we see that as our incentive to continue what we do well for the next 100 years – no resting on our laurels for us.
Johannes Dallmer speaks at the anniversary celebration "100 years of Dallmer".
Dallmer has now been established for 100 years and is more active than ever. Of all the innovations, the CeraWall drainage systems are attracting particular attention. That is because it is the first surface drainage system to separate the shower channel from the drain and enable surface drainage.
Dallmer continues to expand – geographically, technically and in terms of human resources. We open new agencies abroad, invest in new production facilities, launch new innovations on the market which, above all, will forever change the face of drainage level-access showers, and management welcomes two new members.

Helmuth Dallmer's greatest passion was horses. When his horse fell ill with laminitis, it was a formative experience, sending him on a long heart-felt search for an animal-friendly alternative to the horseshoe.
