Hygienic interior specialists PolySto and Hydewa join forces

With Hydewa GmbH joining forces with us as a sister company, we’re combining decades of expertise in hygienic walls, ceilings and surface systems to deliver stronger, more tailored solutions for customers across Europe.

Hydewa is renowned for its long-standing expertise in premium fiberglass-reinforced polyester (FRP) panel solutions for clean and controlled environments. It excels at designing and manufacturing technologically advanced, hygienic surface systems. With this partnership, we'll operate as sister companies and join forces. This will strengthen our market position and significantly expand our ability to deliver high-performance, tailor-made hygiene solutions across different end markets. We're combining our vision of durability and quality. This will enable us to bring enhanced capabilities and a broader portfolio to the market.

In May 2025, we took an important step in our growth trajectory by attracting Sofindev Private Equity Partners — a reputable investment company known for supporting ambitious companies, entrepreneurs and management teams — as a shareholder, alongside our own management team. Today, together with our shareholders, we're reinforcing this commitment by supporting our continued growth and strategic ambitions, marking another milestone in our long-term partnership.

Hydewa: Specialist fulfilling the highest hygiene requirements

Hydewa, headquartered in Germany, has built a strong reputation as a pioneer in hygienic panel systems for environments with strict hygiene and control requirements. Best known for its high-performance, fiberglass-reinforced panels with exceptional durability and hygiene properties, Hydewa has become a trusted partner for industries requiring strict sanitary conditions. With a strong presence in key industry-leading markets such as Germany, Italy, Switzerland and Austria, Hydewa has become an established name across Europe. Over the years, the portfolio has expanded from specialized food processing and cold storage applications to fully integrated hygienic wall and ceiling systems for a wide range of sectors. With decades of technical expertise and a commitment to continuous innovation, Hydewa consistently delivers robust, future-proof products that meet the highest standards of hygiene, safety and performance.

About us: Strong international footprint in hygienic construction

We, PolySto Group, were founded in Belgium over three decades ago and have grown into a leading specialist in the design, production and installation of hygienic interior solutions for high-compliance environments. Our durable wall protection systems and turnkey hygienic finishing concepts are used across the food industry, pharmaceuticals, and other sectors where safety and hygiene are critical. 

We fully unburden our clients by offering a complete range of walls, ceilings, collision protection (including the patented CleanRock kerb) and accessories. In 2025, investment company Sofindev joined us to support our ambitious growth strategy, reinforcing our leading market position and enabling further expansion of our product portfolio and international reach. Today, we continue to build on our reputation as a proactive, solution-driven partner, guiding customers from concept to installation with practical, tailor-made hygiene solutions designed for long-term performance. 

Partnership based on quality and durability

With this strategic partnership, PolySto Group and Hydewa position themselves as European market leaders in hygienic solutions. At the same time, we're significantly expanding our presence in the global market.

Tyler Pinney and Harald Gradwohl (co-founders of Hydewa) and Martin Greiner (Managing Director of Hydewa) explain: “With PolySto Group, we have found a partner whose DNA and passion for durable hygienic solutions fully align with ours at Hydewa. Together, we will preserve the unique cultures of both companies while reinforcing our shared focus on customer centricity, always putting our clients and our people first. As we enter this next phase, Hydewa’s operational management will gradually transition to a new generation of leadership – supported by the founders and working closely with the management team of PolySto Group to ensure long-term strategic alignment.”

Jasper De Jaeger, CEO of PolySto Group, adds: “The partnership between Hydewa and PolySto will further strengthen our commercial presence both within and beyond the Benelux and DACH regions, leveraging each other’s geographical reach and market expertise. While we will operate together under one umbrella, both companies will continue to uphold their own identity, culture, and operational autonomy, while benefitting from the combined strength, complementary capabilities, and shared ambition this partnership brings.”
