If Water Gets In — Or Out — Everything You’ve Built Is at Risk. A leaking roof. A failing expansion joint. A tank that seeps contamination into the ground beneath it. For property owners, facility managers and asset operators, water ingress — or unwanted outflow — isn’t just a maintenance issue. It’s a structural, financial and environmental threat to everything you own or manage. Prokol systems are sealing that vulnerability! Permanently! The Netherlands has managed, controlled and defied water for centuries. It is in our DNA. As a Dutch family-owned company with over 35 years of expertise, we bring that deep-rooted understanding of water behaviour to every product we develop. From raw material to finished product — we develop and manufacture entirely in-house, controlling every detail. This allows us to bring perfectly balanced systems to market that perform as a whole, not as isolated components.
