Soudal – Experts in Sealants, Foams and Adhesives

Soudal New Zealand is a new name to many in the New Zealand construction sector. However, for over 20 years we have been the lead supplier of sealants, foams and adhesives to Holdfast NZ under the iconic Gorilla brand. In November 2018 that relationship changed when Belgium based Soudal proudly stepped in to become sole owner of the Holdfast business in New Zealand. That meant the products, brands and service our customers had come to know and love over 35 years were all retained, but we now had the resourcing and support of the global sealants, foams and adhesives giant that is Soudal.

The change has brought many benefits to our customers. With a commitment to quality that is unrivaled and a real focus on the New Zealand market we pride ourselves on creating strong relationships with our customers and providing tailored solutions to meet their needs.


Every week more than 4 million cartridges and 2 million canisters of PU Foam are manufactured in our state-of-the-art production facilities around the world.   All are manufactured to meet exacting quality standards. To maintain these standards, Soudal became the first company within the industry to achieve the IS0 9001 quality certification. Product consistency and full traceability are therefore ensured across the huge range of over 1,000 chemical formulations.


Soudal is proud to be leading the way in offering an outstanding range of high performance sealants and adhesives that are trade proven, environmentally friendly and get the green tick for;

  • Low VOC
  • ISO 14001 certified
  • Living Building Challenge status

Our commitment to sustainability and thinking green is further evidenced by global initiatives in our production and sales facilities to recycle, reduce and re-purpose waste, utilise sustainable energy sources and optimise the use of all resources fully.


At our sites across the world, our teams of highly qualified scientists, engineers and application technicians develop state of the art formulas, packaging and accessories to perfectly suit the demands of both the industry and end users. Driven by the will to continuously improve and to provide better and more environmentally friendly solutions for its customers, Soudal is leading from the front in product innovation.

From Holdfast to Soudal

but Gorilla is still King of the brands

When the Holdfast business kicked into life (over 35 years ago) in a Waikato garage, no-one would have dared believe that one day it would become one of the largest and most respected suppliers of sealants, foams and adhesives to the New Zealand construction industry.

But that is exactly what happened, and along the way the business won a host of awards, developed a legion of keen followers and grew a truly iconic kiwi brand, Gorilla!

And now under the ownership of Soudal, one of the world’s leading lights in this market, the Gorilla brand is set to even further enhance and strengthen its position of leadership.  Backed by the expertise, innovation and support of the Soudal global team the range of Gorilla branded products which have for so many years been manufactured by Soudal is set to further grow and develop to ensure New Zealand’s love affair with Gorilla continues for another 35 years and beyond.
