HYDRAULIC INHISA
The value of experience
We have been the leading Spanish R&D&i company in design, manufacture, assembly, commissioning and restoration of all types of hydro-mechanical equipment for dams for over 60 years.
We specialise in dam restoration and have extensive experience of renovating bottom outlets, intakes, spillways and replacing hydro-mechanical equipment for safety and regulation applications. Our work also focuses on underwater sealing techniques, so work can be performed without needing to empty the reservoir, and on boring new ducts under load for bottom outlets, middle bottom outlets and intakes for power generation, water supply or energy flows.
We design, fabricate and supply valves and gates, as well as other equipment such as floating intakes, pontoons, shields and dredging and sludge containment systems.
