Flexiflow Gate - Floecksmühle Energietechnik GmbH

Floecksmühle Energietechnik GmbH, based at Bachstraße 62-64 in Aachen, Germany, designs and manufactures inflatable rubber dams and gate systems for water level control and sewage flow management. The company operates a vertically integrated model—handling design, rubber membrane fabrication, assembly, and maintenance from a single facility that includes a dedicated production hall and electrical workshop. Their primary product line is the Schlauchwehre (inflatable rubber dam) system, which uses air- or water-filled rubber membranes to regulate water levels in rivers, canals, and reservoirs. The Kanalschlauchwehr is a newer channel-specific inflatable weir designed for sewage and stormwater flow regulation in confined channel environments. All systems employ a modular assembly approach called Baukastenprinzip (building-block principle), allowing flexible configuration of weir fields to match site-specific requirements. Installations can feature multiple weir fields in a single structure, with overflow-capable water-filled configurations. The company serves both the German domestic market and international markets including the United States, where their products are marketed under the Flexiflow Gate brand.
