Integrated dredging solutions
Construction of marine and coastal structures
At Dragage Maroc, we specialize in the construction of marine and coastal structures, providing effective solutions for coastal protection and conservation. Our experience ranges from the construction of dikes and breakwaters to the implementation of sustainable coastal defense structures.
Comprehensive solutions for the construction of marine and coastal structures
Coastal engineering, which encompasses activities such as land reclamation, port construction, estuary improvement, marine dredging, and coastal protection, often involves the construction of various structures such as seawalls, coastal revetments, breakwaters, and jetties. The primary objective of these works is to mitigate the impact of waves, tides, and storms.
Our services include:
- Construction of seawalls and breakwaters for coastal protection: We design and build seawalls and breakwaters that act as barriers against erosion and flooding, thus protecting coastal infrastructure and communities.
- Construction of breakwaters and jetties: We build breakwaters and jetties that stabilize beaches and improve navigation, thus contributing to the regeneration of coastal dunes and dune stabilization in coastal areas.
- Coastal Protection Structure Design: We offer customized solutions for the design of structures that integrate harmoniously with the environment, promoting the recovery of marine habitats and the protection of the ecosystem.
- Maritime infrastructure maintenance: we provide preventive and corrective maintenance services to ensure the durability and functionality of maritime constructions.
Piers and bulkheads
Dikes are used to protect people and the environment from flooding. Stacked geotextile tubes or earth structures reinforced with geogrids are used to reinforce the core of river dikes, whether natural or artificial. In addition, geotextiles stabilize and reinforce soft soils, which are common in dike foundations. Thanks to their high permeability, geosynthetic materials reduce pore water pressure and minimize wear on artificial dikes, significantly increasing the durability of these structures against flooding.
Jetties and piers
Maintaining or restoring reduced beach levels is effectively achieved by installing geotextile tubes, arranged perpendicular to the shoreline to form pillars or structures that promote beach regeneration. These structures interrupt coastal currents and promote sediment accumulation, thus helping to preserve the existing coastline. In addition, geotextile materials are designed to blend into the marine environment, promoting the growth of aquatic plants and attracting marine wildlife.
Breakwater
Breakwaters play a key role in coastal restoration and protection by dissipating wave energy and promoting sand accumulation on the beach. Compared to traditional rock barriers, geotextile tubes, made of polypropylene or polyester, are filled with locally available materials. This not only reduces the need to purchase external materials but also significantly reduces transportation costs.
Unconnected breakwaters
Unconnected breakwaters are primarily installed near the surf zone to mitigate fast-flowing water currents along the coast. Dragage Maroc uses local materials to fill high-strength geotextile tubes to an optimal height, adapted to the navigation conditions of different applications.
Dunes
Sand dunes, a natural feature of beaches, act as a protective barrier against flooding and erosion. Their formation can be achieved more effectively and stably using a geotextile tube, supplemented by a vegetated surface. This approach not only helps rehabilitate coastlines but also contributes to the enrichment of coastal ecosystems.
Submerged breakwaters and artificial reefs
Submerged breakwaters not only have a low visual impact, but are also a cost-effective solution for reducing strong water currents and protecting marine and coastal structures from erosion. They also act as artificial reefs, promoting the development of marine ecology and attracting a wide variety of organisms. Geotextile tubes enhance these structures by offering advantages such as ease of underwater installation, high cost-effectiveness, and reduced environmental impact.
Coastal protection
Protective structures are designed to protect slopes, hillsides, or cliffs from erosion. In coastal revetment construction, geosynthetics serve multiple functions, such as rockfill protection, filtration, drainage, and separation. These designs incorporate geotextiles or geotextile tube structures, supplemented by geotextile mats to effectively control and stabilize surface erosion.
Cofferdam
Temporary water barriers are economically constructed using geotextile tubes. These tubes are designed to withstand the forces of water acting on the outside of the cofferdams, preventing infiltration into construction areas located below the mean water level. In addition, these nearly impermeable structures facilitate effective beach reclamation.
Erosion-resistant spring structure
Structures installed in marine environments are constantly exposed to erosion, which weakens their foundations over time. To counter this effect, flexible geotextile tubes and bags fit around bridge piers and other monopile gravity bases, mitigating the underwater shear of the soil in their surroundings. These protective measures are reinforced by a protective geotextile cover, providing a complete and sustainable solution.
Pipe support
The weight of pipes can become a problem, especially when passing through poor-quality soils. This weight can cause the pipes to sag, leading to misalignment, opening of joints, and the release of potentially hazardous substances into the surrounding water and soil. To prevent this, geosynthetic supports are used under the pipes, which not only stabilize their position but also prevent corrosion, ensuring a safe and durable solution.
Pipe protection
Pipelines exposed underwater are exposed to risks such as damage from ship anchors or misalignment due to strong underwater currents. To address these issues, geotextile mattresses, filled with cement mortar, or geotextile tubes, filled with locally available materials, are used. These structures are placed over the pipes, acting as a protective and anti-flotation system to ensure their stability and durability.
Innovation and sustainability in maritime construction
We use cutting-edge technologies and high-quality materials to ensure our marine constructions are efficient and environmentally friendly. Our goal is to create sustainable coastal defense structures that minimize environmental impact and promote the conservation of natural resources.
Commitment to coastal protection
We understand the importance of preserving coastlines for future generations. That’s why our seawall, breakwater, and jetty construction projects are designed to provide sustainable solutions to combat erosion and protect coastal areas from the harmful effects of climate change.
With the growing importance of environmental protection, marine and coastal engineering projects are focused not only on infrastructure construction but also on the sustainable management of the marine and coastal environment. In this context, geosynthetic products are being integrated into many projects, offering effective and sustainable solutions. Dragage Maroc makes a significant contribution with approaches that prioritize cost reduction, ease of installation, and harmony with nature.
