Gacon is to become part of the SealteQ Group

Stadskanaal, the Netherlands – SealteQ and Gacon have announced that they are joining forces. Gacon, based in Nijmegen and with over 35 years’ experience in concrete renovation, metal preservation, synthetic flooring and waterproofing, is to become part of the SealteQ Group.

Gacon is a family-run business with around 30 specialists. They carry out metal preservation work both from their own workshop and on-site at project locations. In addition, the team focuses on large-scale projects such as synthetic flooring in industrial, non-residential and data centre settings, as well as the renovation of balconies, galleries, pumping stations and sewage treatment works. As a regular construction partner and subcontractor, they work closely with main contractors, large painting firms and property maintenance companies. This breadth of expertise makes Gacon a valuable addition to the SealteQ Group.

The team will continue to work from Nijmegen for their current clients, and will now also be able to draw on the shared knowledge and innovative working methods within the SealteQ Group.

Michel Gasseling, director of Gacon: “Right from the very first exploratory discussions, it became clear that Gacon and SealteQ are an excellent match. Not only because our activities are very similar, but also in terms of our approach and mindset. Selling a family business is a major step, but we are all convinced that we can continue to grow at SealteQ and that we are ‘in good hands’. The management team remains unchanged and committed to the company, and is looking forward to working with the group companies.”

Martin van der Leest, CEO of SealteQ: “With Gacon, we are strengthening our group with a versatile specialist. The combination of their expertise and our innovative strength ensures that we can offer our customers the best solution in every area.”

Together, Gacon and the SealteQ Group are continuing to build a future-proof and innovative service offering for the maintenance and renovation market.
