“Climate change is intensifying pressures on our oceans — rising seas, eroding coasts, and disrupted ecosystems are no longer distant threats, but urgent realities. Confronting these challenges requires not just awareness, but engineered resilience.”
Based on findings from the by the IPCC Sixth Assessment Report, 2023
Maccaferri offers a complete range of proven technologies for underwater protection, coastal resilience, and marine restoration. From scour and sealine protection to dune reconstruction and algae restoration, our solutions combine technical performance with environmental care.
RenoMac Plus is a prefilled gabion mattress designed for effective scour protection in port and harbour environments. Its robust structure and flexible design allow it to conform to seabed irregularities, ensuring stability around quay walls and jetties. Recent tests conducted at Deltares have demonstrated RenoMac Plus' superior resistance to turbulent flows, validating its performance in demanding marine conditions.
The ACBM is a flexible mattress made of interlinked concrete blocks connected by a rope. It is ideal for protecting subsea pipelines and cables due to its adaptability to uneven seabed profiles. Maccaferri’s patented mobile formwork allows ACBMs to be produced directly at the installation site, significantly reducing transportation costs and environmental impact
SarMac is a flexible, bitumen-filled mattress designed to anchor and protect pipelines and cables in underwater conditions. Its steel wire mesh core and geotextile wrapping ensure durability and safe deployment. Environmentally safe and highly ductile, it adapts to seabed profiles and offers impact resistance—ideal for pipe crossings, rigs, and jetty protection.
RenoMesh BIO supports the restoration of marine vegetation such as algae and seagrass by offering a biodegradable substrate that stabilizes sediments and encourages root anchoring. Designed for minimal environmental impact, it protects young plants during establishment and naturally degrades once the ecosystem is rebalanced.
PMM is a geosynthetic-based mattress solution designed to protect offshore structures against scour. It is made from polymeric geogrids filled with rocks to ensure protection of the seabed. PMMs are available with different types of geogrids, selected according to hydraulic forces, seabed conditions, and installation depth. Their low visual impact and corrosion resistance make them ideal for wind farm foundation
Remedial Filtering Mattresses are flexible and modular engineering solutions designed for protection, stabilization, and filtration in hydraulic or coastal environments subject to erosion or degradation. These mattresses are composed of filtering geotextiles and infill materials (such as sand or aggregates), providing separation and energy dissipation functions that help restore seabed or riverbed stability and reduce sediment transport over time. They are especially suitable for maintenance or enhancement works on existing structures—such as breakwaters, embankments, or coastal defense systems—where fast, simple, and environmentally low-impact installation is required.
MacTubes are high-strength geotextile tubes used to form the structural core of breakwaters, groynes, and dune restoration works. They are filled in situ with a sand-water slurry, creating a stable, cost-effective alternative to traditional rock-based structures. When used as part of a breakwater or shoreline barrier, MacTubes reduce the need for heavy rock, simplify logistics, and can be installed even in areas where natural resources are limited. Their cylindrical form allows for a more flexible and sustainable approach to wave energy dissipation and sediment retention, while minimizing visual and environmental impact
A portfolio capable of supporting every need.
