The Weholite family meets up in Vaasa (24.10.2019)

Ideas, experiences and news

The Weholite family meets up in Vaasa

Uponor Infra organised the Weholite seminar in Finland this September. At the seminar, almost all Weholite Licensees from Europe, Asia, Africa and Latin America met up in the coastal city of Vaasa.

During the two-day seminar, they attended many presentations about new products and heard about challenging and interesting projects carried out around the world.

Especially the new innovative products and structures developed with Wehopanel in recent years sparked plenty of interest and discussion. Among other projects, the seminar presented a fish farming facility delivered to FishGLOBE in Norway – it is the world’s largest plastic structure designed for marine conditions.

The seminar also focused on a wide range of issues related to quality, raw materials and recycling. Current themes highlighted by the visiting presenters also inspired lively discussion at the seminar.

Participants were very pleased with how well planned and organised the event was. They praised it as a valuable opportunity to share ideas, thoughts and experiences and to learn new things. In addition to the excellent organisation of the event, the participants appreciated its open, relaxed, enthusiastic and energetic atmosphere. In the words of many of those who attended: it was truly a meeting of the Weholite family!

Some comments from the participants

“I think this was a very well organised seminar. The Weholite Licensees have become a big family, learning together and sharing innovative, creative ideas with each other.”

“It was a pleasure indeed to meet you all at the Weholite seminar in Finland! The wealth of knowledge and experience within the group is immense and extremely valuable. We do hope that this interaction will continue and lead to more collaboration between the Licensees as well as with Uponor to help bring this technology to the world and build the Weholite brand around the world.” 

“Thank you everyone for all the energy that we shared together during these couple of days! I hope it will help each and every one of us to improve our commitment and performance, both within and beyond the Weholite family.”

“Thanks to the whole Uponor staff for organising the Weholite seminar! It was an eye-opening experience for us as a young Licensee in the Uponor family.”

“I think you deserve big congratulations for a fantastic seminar!”

“I would like to thank you for all the Weholite 2019 presentations! Most of the credit goes to everyone who gave such interesting presentations and to the Uponor team for all their hard work.”

Light, highly durable and easy-to-install Wehopanel structures can be dimensioned and equipped for various purposes, such as tanks, foundation slabs, support structures and pumping station buildings.

Replacing square concrete structures with Wehopanel solutions does away with the need for complex steel reinforcements, time-consuming mould and demolition work, and weather-sensitive concrete casting.
