GeoSwell®: The Ecological Submerged Breakwater Solution Against Coastal Erosion

Innovative submerged breakwater solution to protect coastlines from erosion. Gabion structure with GEOCORAIL® technology promoting marine biodiversity.

GeoSwell®

An ecological and sustainable solution against coastal erosion 

GeoSwell® is an innovative submerged breakwater solution, designed to protect coastlines from erosion while promoting marine biodiversity. 

Made from metal gabions filled with small riprap or shell waste, this structure acts by dissipating wave energy before it reaches the shore, thus limiting coastline degradation.

SEACURE's solution: GeoSwell® 

Designed, sized and installed by SEACURE, GeoSwell® offers an ecological, biomimetic and sustainable alternative to traditional concrete or massive riprap structures. 

Reinforced by the patented GEOCORAIL® technology, it benefits from a natural mineral coating that protects the metal structure from corrosion, while serving as a habitat for marine fauna and flora. 

This unique technology promotes the formation of an artificial reef and actively contributes to the development of local biodiversity, while ensuring the solution's durability. 

Thanks to its modular design, GeoSwell® can be adapted to each site and installed quickly, from project engineering to implementation and maintenance. It constitutes a tailor-made and high-performance solution for coastal protection, combining environmental resilience and technical efficiency.

GeoSwell® advantages : 

  • Reduction of coastal erosion and wave dissipation thanks to an effective submerged structure
  • GEOCORAIL® natural mineral coating: protection against corrosion and increased durability
  • Ecological and biomimetic solution inspired by natural reefs
  • Promotes local marine biodiversity (fauna and flora)
  • Modular structure adapted to each coastal configuration
  • 100% recyclable and carbon-neutral product thanks to the use of limestone as a natural resource
