Artelia has a portfolio of a dozen patents and the associated trademarks in key technologies resulting from the group’s research work.

These patents concern breakwater protection, marine energy and waste management. Royalties from patents and licences are largely reinvested in the group’s research efforts.

blocs artificiels monocouches de carapaces de digues en mer connus sous les noms : ACCROPODE™, ACCROPODE™ II, ECOPODE™ Brise-lames quasi terminés, qui protègent le Port de Pêche de Thengapattinam dans le Tamil Nadu. Ce Port de pêche et ses brises lames sont protégés par des blocs de ciment CORE-LOC™ de 2,0 m3 et 5,0 m3 .

The Artelia group’s most famous patents are in the field of single-layer artificial breakwater armour blocks known under the names ACCROPODE™, ACCROPODE™ II and ECOPODE™, the successors to the Tetrapod. A team of Artelia specialists provides each construction site with customised technical assistance, enabling them to address the specific needs of contractors and extremely diverse site conditions.


Licence contracts for these blocks are issued by Concrate Layer Innovations (CLI) , a subsidiary of the Artelia group. CLI also issues licences for the CORE-LOC™ block developed by the US Army Corps of Engineers. All these products benefit from industrial protection, which is a true guarantee of quality for clients.

The POSIBLOC™ system aids the accurate placing of armour units, reflecting CLI’s constant concern to improve the services offered to construction contractors. By monitoring the placing of each block in real time, this system improves quality and ensures greater efficiency. The system is produced and marketed by our partner Mesuris, which also provides technical assistance.

Wave energy converter

A hydraulic concentrator channels water into a raised basin that is vertically guided, enabling the system to adapt to tidal levels. The water in the basin is turbined to generate electricity. Artelia tested and validated the system in its hydraulics laboratory.

Other patents

Artelia has developed other patented technologies that concern, for example, the storage of solid waste under roads and protection against river erosion.

Furthermore, Artelia is licensed to use patents that it does not own but to whose development it contributed (for example the one concerning the confinement of underground pollutants).
