Dyrhoff Ltd

Dyrhoff specialises in the custom design and supply of inflatable rubber dams and spillway gates, with a history in water control structures dating back to 1989. The company acquired Sumigate from Sumitomo Electric in 2003, a global leader in rubber dams, and has since been involved in the design, supply, and commissioning of over 100 rubber dams and spillway gates across four continents. Dyrhoff also serves as the main European agent for Obermeyer Hydro spillway gates, offering complete systems and steel component manufacturing.

With over 30 years of specialized expertise, Dyrhoff excels in providing tailored water control solutions. They offer flexible services, including full-turnkey options and impartial advice on gate systems. The company's rubber dams follow Japanese Technical Standards, and they are committed to continuous improvement through an active research and development program, holding patents for specific design features.

Dyrhoff operates mainly on a supply-only basis but provides on-site supervision to guide installation contractors through the entire process, from installation to testing and commissioning. Their global reach is evidenced by successful projects across Europe, the Americas, Asia, and Africa, demonstrating their capability to deliver complex water control structures worldwide.
