Dredging, known as capital dredging, involves the removal of large volumes of underwater material — sand, silt, clay, or rock — to support strategic infrastructure projects.

Key applications include:

• Creation of new waterways and navigation channels
• Deepening of existing routes to accommodate larger vessels
• Development of ports, artificial islands, and coastal platforms

The global dredging market is estimated at around USD 30–35 billion, growing at an average annual rate (CAGR) of 3%, driven by increasing maritime traffic, port expansion projects, and coastal protection initiatives.

Industry operators face complex challenges:

• Economic: high equipment and logistics management costs
• Operational: safe and efficient handling of millions of cubic meters of material
• Environmental: minimizing impacts on marine ecosystems and complying with increasingly strict regulations

Innovative solutions, such as flexible pipelines, advanced floats, and monitoring systems, are helping the industry balance productivity, safety, and environmental sustainability.

Safer and More Sustainable

In the mining industry, dredging plays a key role in the extraction, transport and management of sediments and minerals. It enables the recovery of resources such as sand, gravel, coal and precious metals, while efficiently managing tailings and waste materials from processing operations.

However, mining operators face increasingly challenging conditions: abrasive slurries, high energy requirements, complex maintenance and stricter environmental regulations. To meet these needs, Kiasma Group designs advanced dredging and discharge systems that combine technological innovation, operational reliability and environmental responsibility.

Our co-extruded HDPE pipes, with anti-abrasive and friction reducer layers, are specially designed for mining conditions. They offer maximum wear resistance, optimised hydraulic efficiency and long service life, reducing energy consumption, micro-particle dispersion and overall operating costs. Designed for mining, Kiasma Group systems integrate seamlessly with floating and land-based installations, offering a complete and sustainable dredging solution.
