An innovation culture in designing your project

Hydroplus’ constant investment in research and development is aimed at improving the performance of solutions and inventing new systems to increasingly widen its scope of applications. In order to address specific issues, Hydroplus is testing solutions within its own hydraulic testing laboratory, the Hydrolab, and is developing programmes in partnership with renowned French and international research centres and laboratories.

High-level skills

The high level experts in hydraulics, civil engineering and metal constructions of Hydroplus® optimise the design, methods and completion times, guaranteeing the costs, together with the Main Contractors and their Consulting Engineers and can rely on the engineering division of VINCI Construction Grands Projets, which gathers more than 200 specialists. This approach makes it possible to control project risks, avoid work hazards and optimise the quality of the work. Our teams are active members of several international professional unions and scientific bodies.

Establishments near your projects

Our permanent establishments in Europe, Africa, North America, South America, Asia and Oceania are available to aid you with your projects on all continents, with detailed knowledge of local technical and regulatory issues.


Customised innovations for your hydraulic structures

Hydroplus is a subsidiary of VINCI, the world leader in concessions and construction. For over 20 years, Hydroplus® has been inventing, designing, manufacturing and installing independent, reliable and economical hydraulic equipment worldwide, to meet the challenges of the growing demand for water (drinking water, hydropower and irrigation) and to protect populations and infrastructures from floods.

Hydroplus has invented equipment that increases the storage capacity and safety of dams, as well as providing better flood control for dikes°:

  • Classic Fusegate
  • Folding Fusegate
  • Smart Fusegate

Hydroplus distributes and installs Hydroliennes, which enable life to be quickly restored to eutrophic water bodies, in partnership with Aerolac, a Vinci company that designs them.

Hydroplus is distinguished by a customer approach based on consulting and the understanding of the technical issues and challenges of each project. The outstanding quality of its work is evidenced by numerous international awards.

Hydroplus offers Main Contractors and Project Managers the most advantageous solutions in terms of cost, performance and safety, from the project design stage to the installation of turnkey structures.


Technologies for the EnvironmentIncreasing the capacity of reservoir dams with Hydroplus systems makes it possible to delay the need to build new structures and thus reduces the social and environmental impact relating to the flooding of new land.

A greater protection of people and property located downstream from dams and dikes contributes to the strengthening of local economies and the safety of the population.

Hydroliennes replenish the oxygen and destratify eutrophic water bodies: they restore life to the ecosystem.

The systems set up by Hydroplus are independent and non-polluting, they require no energy other than the natural power of water and wind. Their manufacture is more carbon efficient than traditional solutions involving volumes of earth and concrete, or much greater quantities of metal materials.

An integrated partnership approach

The company has worldwide presence. Local businesses and communities are viewed as essential partners and are invited to participate in the construction and installation of various solutions. Our partner's staff and Owner's staff are involved and trained to the building and operation of the Hydroplus systems.

High Environmental Quality Standards

Our commitment to quality, environment and safety is guaranteed by design and worksite methods, geared at the management of risk, quality, people and property safety, and the environment. The combined practices of Hydroplus® and their subcontractors and suppliers are endorsed by ISO 9001, ISO 14 001 and ILO-OSH certifications which recognize the company’s adherence to highest standards.
