History

1956
The firm is founded in 1956, when Karl Skjøth establishes the smithy Folding Smed.

Karl is an enterprising metalworker and quick becomes known and acknowledged in the agricultural sector for his top-quality work. At the same time, Karl's wife Petra founds a laundry. She invests in her first washing machine and provides laundry services for local households, while also helping in the smithy. As the family gradually grows, sons are given jobs in the smithy and grow up in their father's footsteps to the sound of hammer on anvil.     

1960s
The metalworking business expands. Karl develops the business and begins to engineer efficient machinery customised for the concrete industry. Things really take off. Success breeds success, and the firm invests in new employees and new machinery. Karl is a little "old-fashioned", and won't invest on borrowed money.

1970s
The firm continues to grow, and becomes involved in a new business area. Karl helps build the local waste water treatment plant. It's an exciting challenge that Karl embarks on with passion and vigour as it involves the development and production of new, environmentally friendly methods of waste water treatment. At the end of the 70s, Karl takes the important decision that the firm will focus on further development of environmentally friendly waste water management systems.

1980s
The business grows and becomes renowned throughout most of Denmark. One treatment plant after the other is designed, built and serviced. New advances are made, both technological and geographical, new employees hired, new machines bought and new customers gained.

1993
It is only natural that Petra and Karl's son and daughter-in-law, Aslak and Helle, take over the metalworking business.

Aslak takes a professional approach, implementing new market-oriented methods, and sees new development possibilities beyond the country's borders. It is now that the firm becomes known as Aquagain. This name is used for marketing purposes and is added to the firm's original name to form the new company name: Aquagain – Folding Smed A/S.

1990s
Aquagain rises to the task, both at home and abroad. Bigger and bigger plants are designed, built and serviced. Systematised professionalism ensures that all customer wishes and requirements are fulfilled.

2006
Aquagain builds and inaugurates a modern new factory. The company grows, with new employees and more new machinery. New technologies and efficient new methods ensure that the solutions, products and services supplied create maximum value for customers.

2000s
Aquagain founds Aquagain Service, a service division with a specialist team that focuses on offering customers top-quality maintenance, repair, acute assistance and general service + a sales office established in Norway.

2010s
During the 2010s, Aquagain significantly strengthened its technical and project capabilities. The company expanded its internal technical department with additional specialists in construction, 3D design, and project management, enabling the delivery of even more complex and customised solutions for the water and wastewater sectors in both Denmark and Norway.

2016
As part of a strategic initiative in the Norwegian market, Aquagain opened a permanent Norwegian branch in Oslo with local management. At the same time, Aquagain Service was integrated as an independent department within Aquagain – Folding Smed A/S. This meant that the service unit was no longer a separate company, but became part of the core business — providing greater flexibility and an even stronger service experience for customers.

2020s
Throughout the 2020s, Aquagain continued its development as a modern environmental technology project and service partner. The technical department and project organisation were continuously strengthened in both Denmark and Norway to support larger facilities, new technologies, and increasingly complex customer needs.

2021
From January 2021, Aquagain became the sales and service partner for HUBER SE in Denmark. The partnership with one of the world’s leading manufacturers of wastewater equipment enhanced Aquagain’s product portfolio and service offerings, giving customers access to complete HUBER solutions with local consultancy, installation, and service.

2023
In 2023, Aquagain entered into a partnership with PyroDry for the sale, installation, and subsequent service of complete PyroDry pyrolysis plants in Denmark and Norway. The agreement marked a new technological direction for Aquagain, focusing on the future of sustainable sludge and resource management.

2026
In 2026, Aquagain celebrates its 70th anniversary. It marks 70 years with hands in steel, minds in technology, and eyes on clean water and reliable solutions. From the first tasks in 1956 to today’s projects and services across Denmark and Norway, we have grown alongside the industry — but one thing has remained unchanged: We make an effort.

The anniversary is an opportunity to celebrate the journey, thank customers and partners for their trust, and look ahead. With a strong foundation and decades of experience behind us, we are ready for the next chapter. Aquagain – Folding Smed A/S remains family-owned by the Skjøth family.
