SubMac

As maritime infrastructure expands, stabilising the seabed has become a critical challenge in modern engineering. To address this, SubMac offers a flexible, high-performance system designed for seabed stabilisation and shoreline protection. Constructed with a geotextile coupled with a geogrid reinforcement and ballasted with concrete blocks, SubMac® ensures long-term stability and durability. Its modular design, available in different sizes and thicknesses, allows for precise adaptation to specific project needs, making it an ideal solution for ports, offshore structures, and dredging operations. 

Tested in compliance with Det Norske Veritas DNV-RP-F107 standards, SubMac demonstrates exceptional resilience, resisting up to 100% greater than the maximum advised energy. This ensures superior performance even in demanding marine environments. With Maccaferri’s expertise in geotechnical engineering, SubMac ® provides a reliable, sustainable solution to prevent the displacement of sediment and guarantee stable seabeds for modern port facilities and offshore operations.
