Our solutions are designed to protect structures and riverbanks against erosion, scouring, and water-related stresses. This includes the design and supply of flexible and sustainable systems for:

• stabilizing riverbanks and slopes in wetlands against river or torrential erosion
• protection against scouring that may occur at the base of structures (bridges, docks, piers, levees, etc.)
• combating coastal erosion
• dissipating energy from waves and/or currents
• protecting subsea pipelines and networks.

Geobrugg’s solutions for hydraulic engineering and coastal protection are versatile and can be adapted to a wide range of structures thanks to their flexible, durable, and customizable design. They are used to:

• Protect against scouring
  The foundations of retaining walls, sheet pile walls, docks, piers, dikes, port structures, or foundations exposed to natural or propeller-induced currents.
  
  
• Coastline stabilization
  Protecting beaches, dunes, coastal structures, breakwaters, groins, piers/jetties, and areas subject to wave action.
  
  
• Combating bank erosion
  Stabilizing riverbanks, canals, rivers, and wetlands subject to high flow velocities.
  
  
• Protecting Subsea Cables and Pipelines
  Mechanical protection of conduits, cables, and pipelines laid on the seabed or riverbed.
  
  
• Creating or Stabilizing Mooring Buoys
  Use as flexible ballast for anchors, moorings, floats, or submerged structures.

Geobrugg employs maritime and coastal experts all over the world to support you in case of questions. We collaborate closely with you in many languages. We see our role as your reliable design support. If we find that our solutions will not be suitable for a concrete project or would not add significant value, we will always be transparent.

Marine environments expose structures to continuous dynamic loading, uplift, and erosion. The key challenge is controlling hydraulic energy while maintaining long-term stability under cyclic loading. Systems such as TECCO^® CELL and TECCO^® TRAPUNTA address these challenges by combining mass, flexibility and controlled energy dissipation.

Systems (mattresses) made of high-tensile wire mesh filled with stones form a porous and flexible structure: the voids dissipate hydraulic energy, while the mass of the fill and the strength of the mesh stabilize the assembly and prevent the materials from escaping.

High-tensile duplex stainless steel, e.g. 1.4462, offers excellent resistance to chloride-induced corrosion, fatigue, and mechanical loading, for example abrasion. This makes it ideal for long-term use in seawater, splash zones, and tidal areas. All TECCO^® maritime systems are designed to maintain structural integrity under aggressive marine conditions.

Our protective structures offer several major advantages. Their flexible, porous structure allows them to:

• Conform to ground movements
  They adapt to differential settlement or scouring without deteriorating or losing their effectiveness.
  
  
• Dissipate hydraulic energy
  The voids in the fill material absorb and reduce the impact of currents and waves, limiting erosion.
  
  
• Facilitate installation
  The components are lightweight when empty, can be shipped as a kit, and are quick to install.
  
  
• Provide a durable solution
  The high-strength 318 stainless steel mesh confines the stones and maintains performance over time, even in corrosive and abrasive environments.
  

TECCO^® maritime Systems offer several advantages in these areas:

• Exceptional durability
  Their high-tensile stainless steel mesh, which is highly corrosion-resistant, ensures remarkable longevity in marine environments (in accordance with Eurocode 3 1993-1-4), far surpassing that of traditional solutions.
  
  
• Natural Materials and Reduced Logistics
  The system optimizes material thickness and uses local natural stone fill of standard grain size, reducing transportation costs and limiting the carbon footprint. Its lightweight design (when empty) and kit packaging greatly simplify logistics: in some cases, a single container is sufficient for several hundred square meters of installation.
  
  
• Reduced environmental impact throughout the entire life cycle
  Their long service life, adaptability to changing conditions, low maintenance requirements, and the ability to reuse or remove them contribute to a more sustainable life cycle and reduced operating costs.

• Durable Stainless Steel Material
  All TECCO^® CELL products are manufactured from 1.4462 / AISI 318 stainless steel, an alloy that is highly resistant to seawater, chlorides, and corrosion. This ensures a long service life, even in areas exposed to sea spray or tidal action.
  
  
• No harmful emissions into the environment
  Unlike systems that use plastic or polymer materials, stainless steel does not release harmful particles into the natural environment, making it an ecosystem-friendly solution.

TECCO^® CELL is installed in situ and is ideally suited for shoreline protection, riverbanks, and sloped revetments where geometry varies, and natural integration is desired.

TECCO^® CELL MOBILE is a prefabricated system designed for hydraulically highly loaded zones, enabling rapid installation and consistent quality in areas exposed to strong currents or wave action.

In our TECCO^® CELL systems, stones are fully confined within high-strength wire cells. This creates a composite structure where hydraulic forces act on the entire mattress rather than on individual stones. Even under high wave impact or strong currents, the stones remain locked in place. Our prefabricated solutions serve as finite elements themselves, whereas TECCO^® CELL is conceived as a monolithic structure along the entire installation length with integrated small compartments.

The rhomboidal mesh geometry ensures uniform load distribution, high tensile strength in multiple directions, and stable stone confinement. Because of its diamond shape, the mesh does not elongate significantly under load, always keeping the stone infill in place. This setup is essential for maintaining hydraulic performance under repeated, multidirectional loading, which is typical in marine environments.

TECCO^® TRAPUNTA is a prefabricated heavy-duty mattress specifically designed for scour protection. Due to its high mass and robust construction, it is used around quay walls, offshore foundations, and port structures to protect against local erosion caused by propeller wash, waves, and currents.

TECCO^® MANTA is a prefabricated, large-area, heavy-duty mattress designed for surface weighting and protection. It is particularly suited for seabed stabilization, covering large areas efficiently, and providing both mechanical protection and controlled surface shaping in offshore and nearshore applications.
